Toyota Sienna Service Manual / Navigation / Navigation system / System normal condition check

1. CHECK 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 radio and navigation assembly may determine that a longer route is quicker.
Even when distance priority is high, the shortest route is not shown. Some paths 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 actual position. If the vehicle starts before the navigation system activates, the system may not react.
When running on certain types of roads, especially new roads, the vehicle position deviates from the actual position. When the vehicle is driving on new roads not available on the map disc, the system attempts to match it to another nearby road, causing the position mark to deviate.
