AV-368 < SYMPTOM DIAGNOSIS > [NAVIGATION WITH BOSE] NORMAL OPERATING CONDITION - Because calculation of the current location cannot be done when traveling with the ignition off, for example when traveling by ferry or when being towed, the location before travel is displayed. If the precise location can be detected with GPS, the location will be corrected. Vehicle Mark Jumps In the following cases, the vehicle mark may appear to jump as a result of automatic correction of the current location: • When map matching has been done - If the current location and the vehicle mark are different when map matching is done, the vehicle mark may seem to jump. At this time, the location may be “corrected” to the wrong road or to a location which is not on a road. • When GPS location correction has been done - If the current location and the vehicle mark are different when the location is corrected using GPS measure- ments, the vehicle mark may seem to jump. At this time, the location may be “corrected” to a location which is not on a road. Vehicle Mark is in a River or Sea The navigation system moves the vehicle mark with no distinction between land and rivers or sea. If the vehi- cle mark is somehow out of place, it may appear that the vehicle is driving in a river or the sea. Vehicle Mark Automatically Rotates The system wrongly memorizes the rotating status as stopping when the ignition switch is turned ON with the turntable rotating. That causes the vehicle mark to rotate when the vehicle is stopped. When Driving on Same Road, Sometimes Vehicle Mark is in Right Place and Sometimes it is in Wrong Place The conditions of the GPS antenna (GPS data) and gyroscope (angular speed sensor) change gradually. Depending on the road traveled and the operation of the steering wheel, the location detection results will be different. Therefore, even on a road on which the location has never been wrong, conditions may cause the vehicle mark to deviate. |
