I J POSITION DETECTION PRINCIPLE The navigation system periodically calculates the current vehicle position according to the following three types of signals. • Travel distance of the vehicle as determined by the vehicle speed sensor • Vehicle turning angle determined by the gyroscope (angular speed sensor) • The travel direction of the vehicle determined by the GPS antenna (GPS information) The current position of the vehicle is then identified by comparing the calculated vehicle position with map data, which is stored in the HDD (Hard Disk Drive) (map-matching), and indicated on the screen with a current location mark. More accurate data is used by comparing position detection results from GPS to the map-matching. The current position is calculated by detecting the travel distance from the previous calculation point, and its direction change. • Travel distance The travel distance is generated from the vehicle speed sensor input signal. The automatic distance correction function is adopted for preventing a miss-detection of the travel distance because of tire wear etc. • Travel direction The gyroscope (angular velocity sensor) and GPS antenna (GPS information) generate the change of the travel direction. Both have advantages and disadvantages as per the following descriptions. Revision: 2008 May K L M AV JSNIA0177GB O P SEL684V AV-19 2009 GT-R NAVIGATION SYSTEM < FUNCTION DIAGNOSIS > Type Gyroscope (angular velocity sensor) GPS antenna (GPS information) Advantage The turning angle is precisely detected. The travel direction (North/South/East/West) is detected. [BASE AUDIO WITH NAVIGATION] Disadvantage Errors are accumulated when driving a long distance without stopping. The travel direction is not precisely detected when driving slowly. Input signals are prioritized in each situation. However, this order of priority may change in accordance with more detailed travel conditions so that the travel direction is detected more accurately. MAP-MATCHING Map-matching repositions the vehicle on the road map when a new location is judged to be more accurate. This is done by comparing the current vehicle position (calculated by the normal position detection method) from the map data stored in the HDD (Hard Disk Drive). SEL685V There is a possibility that the vehicle position may not be corrected in the following case, and when vehicle is driven over a certain distance or time in which GPS information is hard to receive. Correct manually the current location mark on the screen. • In map-matching, several alternative routes are prepared and prioritized in addition to the road judged as currently driving on. Therefore, due to errors in the distance and/or direction, an incorrect road may be prioritized, and the current location mark may be repositioned to the incorrect road. If two roads are running in parallel, they are of the same priority. Therefore, the current location mark may appear on either of them alternately, depending on maneuvering of the steering wheel and configuration of the road, etc. SEL686V • Map-matching does not function correctly when road on which the vehicle is driving is new, etc. and not recorded in the map data. Also, map-matching does not function correctly when road pattern stored in the map data and the actual road pattern are different due to repair, etc. Therefore, the map-matching function judges other road as a currently driving road if the road is not in the map, and displays the current location mark on it. Later, the current location mark may be repositioned to the road if the correct road is detected. • Effective range for comparing the vehicle position and travel direction calculated by the distance and direction with the road data is limited. Therefore, correction by map-matching is not possible when there is an excessive gap between current vehicle position and the position on the map. JSNIA0180GB GPS (GLOBAL POSITIONING SYSTEM) Revision: 2008 May AV-20 2009 GT-R NAVIGATION SYSTEM [BASE AUDIO WITH NAVIGATION] < FUNCTION DIAGNOSIS > GPS (Global Positioning System) is developed for and is controlled by the US Department of Defense. The system utilizes GPS satellites (NAVSTAR), transmitting out radio waves while flying on an orbit around the earth at an altitude of approximately 21,000 km. The receiver calculates the travel position in three dimensions (latitude/longitude/altitude) according to the time lag of the radio waves that four or more GPS satellites transmit (three-dimensional positioning). The GPS receiver calculates the travel position in two dimensions (latitude/longitude) with the previous altitude data if the GPS receiver receives only three radio waves (two-dimensional positioning). GPS position correction is not performed while stopping the SEL526V vehicle. Accuracy of the GPS will deteriorate under the following conditions: • In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes. • The position of GPS satellite affects GPS detection precision. The position detection may not be precisely performed. • The position detection is not performed if GPS receiver does not receive radio waves from GPS satellites. (Inside a tunnel, parking in a building, under an elevated highway etc.) GPS receiver may not receive radio waves from GPS satellites if any object is placed on the GPS antenna. NOTE: • The detection result has an error of approximately 10 m even with a high-precision three dimensional positioning. • There may be cases when the accuracy is lowered and radio waves are stopped intentionally because the GPS satellite signal is controlled by the US trace control center.

Solution F G H I J K L M RELATED TO AUDIO • The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic interference, etc.). Check the symptoms below to diagnose the malfunction. AV • The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and operation of each piece of electrical equipment, and then determine the cause. O NOTE: • CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incorrectly mastered by the customer on a computer. • Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the “red book” Compact P Disc Standard and may not play. Revision: 2008 May AV-157 2009 GT-R NORMAL OPERATING CONDITION < SYMPTOM DIAGNOSIS > Symptom [BASE AUDIO WITH NAVIGATION] Cause and Counter measure Check if the CD/CF was inserted correctly. Check if the CD/CF is scratched or dirty. Check if there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) before using the player. If there is a temperature increase error, the player will play correctly after it returns to the normal temperature. Cannot play If there is a mixture of music CD files (CD-DA data) and MP3/WMA files on a CD, only the music CD files (CD-DA data) will be played. Files with extensions other than “.MP3”, “.WMA”, “.mp3”, or “.wma” cannot be played. In addition, the character codes and number of characters for folder names and file names should be in compliance with the specifications. Check if the disc or the file is generated in an irregular format, This may occur depending on the variation or the setting of MP3/WMA writing applications or other text editing applications. Check if the finalization process, such as session close and disc close, is done for the disc. Check if the CD/CF is protected by copyright. Poor sound quality It takes a relatively long time before the music starts playing. Music cuts off or skips Skipping with high bit rate files Move immediately to the next song when playing The songs do not play back in the desired order. Check if the CD/CF is scratched or dirty. If there are many folder or file levels on the MP3/WMA CD/CF, or if it is a multisession disc, some time may be required before the music starts playing. The writing software and hardware combination might not match, or the writing speed, writing depth, writing width might not match the specifications. Try using the slowest writing speed. Skipping may occur with large quantities if data such as for high bit rate data. When a non-MP3/WMA file has been given an extension of “.MP3”, “.WMA”, “.mp3”, or “.wma”, or when play is prohibited by copyright protection, the player will skip to the next song. The playback order is the order in which the files were written by the software, so the files might not play in the desired order. Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other sources, is not a malfunction. NOTE: • Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings blocking the signal. • Multi-path noise: This noise results from a time difference between the broadcast waves directly from the station arriving at the antenna and the waves reflected by mountains or buildings. RELATED TO VEHICLE ICON Symptom Possible cause This is because the quantity of the displayed information is reduced so that the screen does not become too crowded. There is also a chance that names of the roads may be displayed multiple times, and the names appearing on the screen may be different because of a processing procedure. The vehicle was transported after the ignition switch was pushed off, for example, by a ferry or car transporter. The position and direction of the vehicle icon may be incorrect depending on the driving environments and the levels of positioning accuracy of the navigation system. Because the new road is not stored in the map data, the system automatically places the vehicle icon on the nearest road available. Possible solution Names of roads differ between Plan View and Birdview™. This is not a malfunction. Drive the vehicle for a while on a road where GPS signals can be received. This is not a malfunction. Drive the vehicle for a while to automatically correct the position and direction of the vehicle icon. Updated road information will be included in the next version of the map data. The vehicle icon is not displayed in the correct position. When the vehicle is traveling on a new road, the vehicle icon is located on another road nearby. Revision: 2008 May AV-158 2009 GT-R NORMAL OPERATING CONDITION < SYMPTOM DIAGNOSIS > Symptom The screen does not switch to the night screen even after turning on the headlights. The map does not scroll even when the vehicle is moving. The vehicle icon is not displayed. Possible cause The daytime screen was set the last time the headlights were turned on. The current location map screen is not displayed. The current location map screen is not displayed. When using tire chains or replacing the tires, speed calculations based on the speed sensor may be incorrect. The map data has a mistake or is incomplete (the vehicle icon position is always misaligned in the same area). [BASE AUDIO WITH NAVIGATION] Possible solution Set the screen to the night screen mode using when you turn on the headlights. Push . Push . Drive the vehicle for a while (at approximately 19 MPH for about 30 minutes) to automatically correct the vehicle icon position. If this does not correct the vehicle icon position, contact an NISSAN/INFINITI dealer. Updated road information will be included in the next version of the map data. A B C D The location of the vehicle icon is misaligned from the actual position. E RELATED TO ROUTE CALCULATION AND VISUAL GUIDANCE Symptom Waypoints are not included in the auto reroute calculation. Possible cause Waypoints that you have already passed are not included in the auto reroute calculation. Route calculation has not yet been performed. Route information is not displayed. You are not driving on the suggested route. Route guidance is set to off. Route information is not provided for certain types of roads (roads displayed in gray). The auto reroute calculation (or detour calculation) suggests the same route as the one previously suggested. Route calculations took priority conditions into consideration, but the same route was calculated. Possible solution If you want to go to that waypoint again, you need to edit the route. Set the destination and perform route calculation. Drive on the suggested route. Turn on route guidance. This is not a malfunction. F G H I This is not a malfunction. J A waypoint cannot be added. Five waypoints are already set on the route, including ones that you have already passed. A maximum of 5 waypoints can be set on the route. If you want to go to 6 or more waypoints, perform route calculations multiple times as necessary. Reset the destination to a main or ordinary road, and recalculate the route. Set a more distant destination. Divide your trip by selecting one or two intermediate destinations, and perform route calculations multiple times. Set [Use Time Restricted Roads] to off. K L Roads near the destination cannot be calculated. The starting point and destination are too close. The suggested route is not displayed. M The starting point and destination are too far away. AV There are time restricted roads (by the day of the week, by time) near the current vehicle location or destination. The part of the route that you have already passed is deleted. A route is managed by sections between waypoints. If you passed the first waypoint, the section between the starting point and the waypoint is deleted. (It may not be deleted depending on the area.) If there are restrictions (such as one-way streets) on roads close to the starting point or destination, the system may suggest an indirect route. The system may suggest an indirect route because route calculation does not take into consideration some areas such as narrow streets (gray roads.) O This is not a malfunction. P Adjust the location of the starting of the starting point or destination. Reset the destination to a main or ordinary road, and recalculate the route. An indirect route is suggested. Revision: 2008 May AV-159 2009 GT-R NORMAL OPERATING CONDITION < SYMPTOM DIAGNOSIS > Symptom The landmark information does not correspond to the actual information. The suggested route does not exactly connect to the starting point, waypoints, or destination. Possible cause This may be caused by insufficient or incorrect map data. [BASE AUDIO WITH NAVIGATION] Possible solution Updated information will be included in the next version of the data. Set the starting point, waypoints and destination on a main road, and perform route calculation. There is no data for route calculation closes to these locations. RELATED TO VOICE GUIDANCE Symptom Possible cause Voice guidance is only available at certain intersections marked with? In some case, voice guidance is not available even when the vehicle should make a turn. Voice guidance is not available The vehicle has deviated from the suggested route. Voice guide is set to off. Route guidance is set to off. The guidance contact does not correspond to the actual condition. The contact of voice guidance may vary, depending on the types of intersections at which turn are made. Possible solution This is not a malfunction. Go back to the suggested route or request route calculation again Turn on voice guidance. Turn on voice guidance. Follow all traffic rules and regulations. RELATED TO TRAFFIC INFORMATION Symptom Possible cause The traffic information is not set to on. Possible solution Set the traffic information to on. The traffic information is not displayed You are in an area where traffic information is not avail- Scroll to an area where traffic information is able available You have not subscribed to XM NavTraffic or, your subCheck your subscription status of XM NavTraffic. scription to XM NavTraffic has expired. The map scale is set at a level where the display of icons is impossible. Check that the map scale is set at a level in which the display of icons is possible. The automatic detour search is not intended for avoiding traffic jams. It searches for the fastest route taking into consideration such things as traffic jams. Observe the actual road condition and follow the instructions on road for detour when necessary. If the road closure is for certain, use detour function and set the detour distance to avoid the closed road section. Observe the actual road conditions and regulations. Always observe safe driving practices and follow all traffic regulations. With the automatic detour route search ON, no detour route is set to avoid congested areas. The route does not avoid road section with traffic information stating it is closed due to road construction. Traffic information displayed differs from information from other media (e.g. radio). There is no faster route compared to the current route, based on the road network and traffic information. The navigation system is designed not to avoid this event because the actual period of closure may differ from the declared roadwork period. Other media may use different information sources.

I J POSITION DETECTION PRINCIPLE The navigation system periodically calculates the current vehicle position according to the following three types of signals. • Travel distance of the vehicle as determined by the vehicle speed sensor • Vehicle turning angle determined by the gyroscope (angular speed sensor) • The travel direction of the vehicle determined by the GPS antenna (GPS information) The current position of the vehicle is then identified by comparing the calculated vehicle position with map data, which is stored in the HDD (Hard Disk Drive) (map-matching), and indicated on the screen with a current location mark. More accurate data is used by comparing position detection results from GPS to the map-matching. The current position is calculated by detecting the travel distance from the previous calculation point, and its direction change. • Travel distance The travel distance is generated from the vehicle speed sensor input signal. The automatic distance correction function is adopted for preventing a miss-detection of the travel distance because of tire wear etc. • Travel direction The gyroscope (angular velocity sensor) and GPS antenna (GPS information) generate the change of the travel direction. Both have advantages and disadvantages as per the following descriptions. Revision: 2008 May K L M AV JSNIA0177GB O P SEL684V AV-193 2009 GT-R NAVIGATION SYSTEM < FUNCTION DIAGNOSIS > Type Gyroscope (angular velocity sensor) GPS antenna (GPS information) Advantage The turning angle is precisely detected. The travel direction (North/South/East/West) is detected. [BOSE AUDIO WITH NAVIGATION] Disadvantage Errors are accumulated when driving a long distance without stopping. The travel direction is not precisely detected when driving slowly. Input signals are prioritized in each situation. However, this order of priority may change in accordance with more detailed travel conditions so that the travel direction is detected more accurately. MAP-MATCHING Map-matching repositions the vehicle on the road map when a new location is judged to be more accurate. This is done by comparing the current vehicle position (calculated by the normal position detection method) from the map data stored in the HDD (Hard Disk Drive). SEL685V There is a possibility that the vehicle position may not be corrected in the following case, and when vehicle is driven over a certain distance or time in which GPS information is hard to receive. Correct manually the current location mark on the screen. • In map-matching, several alternative routes are prepared and prioritized in addition to the road judged as currently driving on. Therefore, due to errors in the distance and/or direction, an incorrect road may be prioritized, and the current location mark may be repositioned to the incorrect road. If two roads are running in parallel, they are of the same priority. Therefore, the current location mark may appear on either of them alternately, depending on maneuvering of the steering wheel and configuration of the road, etc. SEL686V • Map-matching does not function correctly when road on which the vehicle is driving is new, etc. and not recorded in the map data. Also, map-matching does not function correctly when road pattern stored in the map data and the actual road pattern are different due to repair, etc. Therefore, the map-matching function judges other road as a currently driving road if the road is not in the map, and displays the current location mark on it. Later, the current location mark may be repositioned to the road if the correct road is detected. • Effective range for comparing the vehicle position and travel direction calculated by the distance and direction with the road data is limited. Therefore, correction by map-matching is not possible when there is an excessive gap between current vehicle position and the position on the map. JSNIA0180GB GPS (GLOBAL POSITIONING SYSTEM) Revision: 2008 May AV-194 2009 GT-R NAVIGATION SYSTEM [BOSE AUDIO WITH NAVIGATION] < FUNCTION DIAGNOSIS > GPS (Global Positioning System) is developed for and is controlled by the US Department of Defense. The system utilizes GPS satellites (NAVSTAR), transmitting out radio waves while flying on an orbit around the earth at an altitude of approximately 21,000 km. The receiver calculates the travel position in three dimensions (latitude/longitude/altitude) according to the time lag of the radio waves that four or more GPS satellites transmit (three-dimensional positioning). The GPS receiver calculates the travel position in two dimensions (latitude/longitude) with the previous altitude data if the GPS receiver receives only three radio waves (two-dimensional positioning). GPS position correction is not performed while stopping the SEL526V vehicle. Accuracy of the GPS will deteriorate under the following conditions: • In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position changes. • The position of GPS satellite affects GPS detection precision. The position detection may not be precisely performed. • The position detection is not performed if GPS receiver does not receive radio waves from GPS satellites. (Inside a tunnel, parking in a building, under an elevated highway etc.) GPS receiver may not receive radio waves from GPS satellites if any object is placed on the GPS antenna. NOTE: • The detection result has an error of approximately 10 m even with a high-precision three dimensional positioning. • There may be cases when the accuracy is lowered and radio waves are stopped intentionally because the GPS satellite signal is controlled by the US trace control center.

Solution RELATED TO AUDIO • The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic interference, etc.). Check the symptoms below to diagnose the malfunction. • The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning. Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and operation of each piece of electrical equipment, and then determine the cause. NOTE: • CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA) or could be incorrectly mastered by the customer on a computer. • Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the “red book” Compact Disc Standard and may not play. Revision: 2008 May AV-322 2009 GT-R NORMAL OPERATING CONDITION < SYMPTOM DIAGNOSIS > Symptom [BOSE AUDIO WITH NAVIGATION] Cause and Counter measure Check if the CD/CF was inserted correctly. Check if the CD/CF is scratched or dirty. Check if there is condensation inside the player, and if there is, wait until the condensation is gone (about 1 hour) before using the player. If there is a temperature increase error, the player will play correctly after it returns to the normal temperature. A B C Cannot play If there is a mixture of music CD files (CD-DA data) and MP3/WMA files on a CD, only the music CD files (CD-DA data) will be played. Files with extensions other than “.MP3”, “.WMA”, “.mp3”, or “.wma” cannot be played. In addition, the character codes and number of characters for folder names and file names should be in compliance with the specifications. Check if the disc or the file is generated in an irregular format, This may occur depending on the variation or the setting of MP3/WMA writing applications or other text editing applications. Check if the finalization process, such as session close and disc close, is done for the disc. Check if the CD/CF is protected by copyright. D E F Poor sound quality It takes a relatively long time before the music starts playing. Music cuts off or skips Skipping with high bit rate files Move immediately to the next song when playing The songs do not play back in the desired order. Check if the CD/CF is scratched or dirty. If there are many folder or file levels on the MP3/WMA CD/CF, or if it is a multisession disc, some time may be required before the music starts playing. The writing software and hardware combination might not match, or the writing speed, writing depth, writing width might not match the specifications. Try using the slowest writing speed. Skipping may occur with large quantities if data such as for high bit rate data. When a non-MP3/WMA file has been given an extension of “.MP3”, “.WMA”, “.mp3”, or “.wma”, or when play is prohibited by copyright protection, the player will skip to the next song. The playback order is the order in which the files were written by the software, so the files might not play in the desired order. G H I Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other sources, is not a malfunction. NOTE: • Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings blocking the signal. • Multi-path noise: This noise results from a time difference between the broadcast waves directly from the station arriving at the antenna and the waves reflected by mountains or buildings. J K RELATED TO VEHICLE ICON Symptom Possible cause This is because the quantity of the displayed information is reduced so that the screen does not become too crowded. There is also a chance that names of the roads may be displayed multiple times, and the names appearing on the screen may be different because of a processing procedure. The vehicle was transported after the ignition switch was pushed off, for example, by a ferry or car transporter. The position and direction of the vehicle icon may be incorrect depending on the driving environments and the levels of positioning accuracy of the navigation system. Because the new road is not stored in the map data, the system automatically places the vehicle icon on the nearest road available. Possible solution L M Names of roads differ between Plan View and Birdview™. This is not a malfunction. AV O Drive the vehicle for a while on a road where GPS signals can be received. This is not a malfunction. Drive the vehicle for a while to automatically correct the position and direction of the vehicle icon. Updated road information will be included in the next version of the map data. The vehicle icon is not displayed in the correct position. P When the vehicle is traveling on a new road, the vehicle icon is located on another road nearby. Revision: 2008 May AV-323 2009 GT-R NORMAL OPERATING CONDITION < SYMPTOM DIAGNOSIS > Symptom The screen does not switch to the night screen even after turning on the headlights. The map does not scroll even when the vehicle is moving. The vehicle icon is not displayed. Possible cause The daytime screen was set the last time the headlights were turned on. The current location map screen is not displayed. The current location map screen is not displayed. When using tire chains or replacing the tires, speed calculations based on the speed sensor may be incorrect. The map data has a mistake or is incomplete (the vehicle icon position is always misaligned in the same area). [BOSE AUDIO WITH NAVIGATION] Possible solution Set the screen to the night screen mode using when you turn on the headlights. Push . Push . Drive the vehicle for a while (at approximately 19 MPH for about 30 minutes) to automatically correct the vehicle icon position. If this does not correct the vehicle icon position, contact an NISSAN/INFINITI dealer. Updated road information will be included in the next version of the map data. The location of the vehicle icon is misaligned from the actual position. RELATED TO ROUTE CALCULATION AND VISUAL GUIDANCE Symptom Waypoints are not included in the auto reroute calculation. Possible cause Waypoints that you have already passed are not included in the auto reroute calculation. Route calculation has not yet been performed. Route information is not displayed. You are not driving on the suggested route. Route guidance is set to off. Route information is not provided for certain types of roads (roads displayed in gray). The auto reroute calculation (or detour calculation) suggests the same route as the one previously suggested. Route calculations took priority conditions into consideration, but the same route was calculated. Possible solution If you want to go to that waypoint again, you need to edit the route. Set the destination and perform route calculation. Drive on the suggested route. Turn on route guidance. This is not a malfunction. This is not a malfunction. A waypoint cannot be added. Five waypoints are already set on the route, including ones that you have already passed. A maximum of 5 waypoints can be set on the route. If you want to go to 6 or more waypoints, perform route calculations multiple times as necessary. Reset the destination to a main or ordinary road, and recalculate the route. Set a more distant destination. Divide your trip by selecting one or two intermediate destinations, and perform route calculations multiple times. Set [Use Time Restricted Roads] to off. Roads near the destination cannot be calculated. The starting point and destination are too close. The suggested route is not displayed. The starting point and destination are too far away. There are time restricted roads (by the day of the week, by time) near the current vehicle location or destination. The part of the route that you have already passed is deleted. A route is managed by sections between waypoints. If you passed the first waypoint, the section between the starting point and the waypoint is deleted. (It may not be deleted depending on the area.) If there are restrictions (such as one-way streets) on roads close to the starting point or destination, the system may suggest an indirect route. The system may suggest an indirect route because route calculation does not take into consideration some areas such as narrow streets (gray roads.) This is not a malfunction. Adjust the location of the starting of the starting point or destination. Reset the destination to a main or ordinary road, and recalculate the route. An indirect route is suggested. Revision: 2008 May AV-324 2009 GT-R NORMAL OPERATING CONDITION < SYMPTOM DIAGNOSIS > Symptom The landmark information does not correspond to the actual information. The suggested route does not exactly connect to the starting point, waypoints, or destination. Possible cause This may be caused by insufficient or incorrect map data. [BOSE AUDIO WITH NAVIGATION] Possible solution A Updated information will be included in the next version of the data. Set the starting point, waypoints and destination on a main road, and perform route calculation. B There is no data for route calculation closes to these locations. C RELATED TO VOICE GUIDANCE Symptom Possible cause Voice guidance is only available at certain intersections marked with? In some case, voice guidance is not available even when the vehicle should make a turn. Voice guidance is not available The vehicle has deviated from the suggested route. Voice guide is set to off. Route guidance is set to off. The guidance contact does not correspond to the actual condition. The contact of voice guidance may vary, depending on the types of intersections at which turn are made. Possible solution This is not a malfunction. D E Go back to the suggested route or request route calculation again Turn on voice guidance. Turn on voice guidance. Follow all traffic rules and regulations. F G RELATED TO TRAFFIC INFORMATION Symptom Possible cause The traffic information is not set to on. You are in an area where traffic information is not available You have not subscribed to XM NavTraffic or, your subscription to XM NavTraffic has expired. The map scale is set at a level where the display of icons is impossible. With the automatic detour route search ON, no detour route is set to avoid congested areas. The route does not avoid road section with traffic information stating it is closed due to road construction. Traffic information displayed differs from information from other media (e.g. radio). There is no faster route compared to the current route, based on the road network and traffic information. Possible solution Set the traffic information to on. Scroll to an area where traffic information is available Check your subscription status of XM NavTraffic. Check that the map scale is set at a level in which the display of icons is possible. The automatic detour search is not intended for avoiding traffic jams. It searches for the fastest route taking into consideration such things as traffic jams. Observe the actual road condition and follow the instructions on road for detour when necessary. If the road closure is for certain, use detour function and set the detour distance to avoid the closed road section. Observe the actual road conditions and regulations. Always observe safe driving practices and follow all traffic regulations. H I The traffic information is not displayed J K L The navigation system is designed not to avoid this event because the actual period of closure may differ from the declared roadwork period.
