NAVIGATION SYSTEM (for Navigation Receiver Type) OPERATION CHECK


  1. CHECK NAVIGATION SYSTEM NORMAL CONDITION


    1. If the symptom is applicable to any of the following, it is intended behavior, and not a malfunction.

      Symptom Answer
      A longer route than expected is chosen. Depending on the road conditions, the navigation receiver assembly may determine that a longer route is quicker.
      Even when distance priority is high, the shortest route is not shown. Some routes may not be advised due to safety concerns.
      When the vehicle is put into motion immediately after the engine starts, the navigation system deviates from the correct position. If the vehicle starts before the navigation system activates, the system may not react.
      When driving on certain types of roads, especially new roads, the vehicle position deviates from the correct position. When the vehicle is driving on new roads not available on the SD card (disc player disc), the system attempts to match it to another nearby road, causing the position mark to deviate.
      Expected arrival time is earlier than current time, or time different from expected arrival time is displayed. If a destination is set to a point where a different time zone is used, the system displays an expected arrival time corresponding to the time zone of the destination. If a location on the sea is set as the destination, the system may display an expected arrival time corresponding to the time zone setting of the vehicle. Check which communication is not used for displaying traffic information.

      The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor or navigation receiver assembly.


      1. The current position mark may be displayed on a nearby parallel road.

      2. A01EXBG

        Immediately after a fork in the road, the current vehicle position mark may be displayed on the wrong road.

      3. A01EYGR

        When the vehicle turns right or left at an intersection, the current vehicle position mark may be displayed on a nearby parallel road.

      4. A01EYIB

        When the vehicle is carried, such as on a ferry, and the vehicle itself is not driving, the current vehicle position mark may be displayed in the position where the vehicle was until a measurement can be performed by the GPS.

      5. A01EUY5

        When the vehicle travels on a steep hill, the current vehicle position mark may deviate from the correct position.

      6. A01EW2A

        When the vehicle makes a continuous turn (e.g. 360, 720, 1080 degrees), the current vehicle position mark may deviate from the correct position.

      7. A01EVXB

        When the vehicle moves erratically, such as constant lane changes, the current vehicle position mark may deviate from the correct position.

      8. A01EX8P

        When the ignition switch is turned to ACC or ON and the vehicle is turned on a turntable before parking, the current vehicle position mark may not indicate the correct direction. The same will occur when the vehicle comes out of the parking garage.

      9. A01ESVS

        When the vehicle travels on a snowy road or a mountain path with tire chains installed or using a spare tire, the current vehicle position mark may deviate from the correct position.

      10. A01EUR4

        When the tires are changed, the current vehicle position mark may deviate from the correct position.

      • As digital TV is a terrestrial broadcast, the digital TV antenna cannot receive the signal in places where the signal may not reach the vehicle, such as mountains or tunnels.

      • Even in areas where digital TV broadcasts for households can be received, the in-vehicle digital TV may not be able to receive the broadcast.


      1. Select "Recheck" to start the DTV reception check.

      2. Check the result displayed when the DTV reception check is complete.

        Tech Tips


        • Do not depend solely on the reception level as a reference value as it may vary depending on the signal conditions such as wave interference.

        • If the result changes after turning the vehicle around, it is not a malfunction, but is caused by a local weak electric field.

        • If the reception level is abnormal, the antenna system or navigation receiver assembly may be malfunctioning.
