A longer route than expected is chosen.Depending on the road conditions, the navigation ECU
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.
