PRE-CHECK

1. TROUBLES UNDER NORMAL CONDITION OF THE NAVIGATION SYSTEM

a. Voice guidance is not performed even though the system is in normal condition when:
1. The destination is not set up.
2. The vehicle is not driving on the set route. (The remaining distance is not displayed at the lower left of the map screen that tells the current position of the vehicle.)
3. "Guidance in Other Modes" is not set up. (In this case no voice guidance is given except on the map screen.)

b. The vehicle icon turns around arbitrarily on the screen even when the system is in normal condition. If the ignition switch is turned to the "ACC" or "ON" position while the vehicle is turning around on the turntable, etc., the Navigation System memorizes the angle speed of that moment as the standard figure. To solve this problem, at the vehicle speed of 0 MPH (0 km/h), turn off the ignition switch, and then turn it to the "ACC" or "ON" position again to see whether any trouble occurs again.

2. INSPECTION OF THE LOCATION WITH TROUBLE OCCURRENCE

a. Check whether the vehicle icon is displayed wrongly in a certain location or in several locations.

HINT: It is difficult to determine the accurate vehicle position when driving on a freeway, a looped road or a road which runs in parallel with another, and immediately after going out of a parking area. In such cases, it is possible that the location of the vehicle icon is displayed incorrectly on the screen.
