Off route events

During a trip, the 
NAV ONE system
offers help if a turn 
is missed or a side 
trip is taken from a
calculated route. It 
also allows changes 
to be made enroute 
— including detours,
changing route criteria
and trip plans, and
canceling navigation.

Leaving a calculated route

Within a short distance of the vehicle leaving a calculated route, the NAV ONE system will recognize the deviation and provide helpful
information. In the case of a missed turn or similar situation, the system will provide voice prompts, such as, “Please make a legal 
U-turn,” to return to the calculated route while the system remains in the active navigation screen.

If a longer deviation is made and the prompts to return to the route are ignored, the system will calculate a new route to the destination
— often a mini-route to intercept the original route at a later point — provided the auto reroute option is turned on. The new route will
be displayed in the active navigation screen and the voice prompts will adjust accordingly. If auto reroute is turned off, the system will
suspend guidance until the user takes some action such as [Detour] or [Cancel].
