navigation system will recalculate a new route automatically.
<Detour Menu>
<Avoid Part of Route>
You can change your route via four functions as follows:
• Avoid part of route
Make a detour to avoid some part of existing route.
• Avoid roadblock
Make a detour to avoid a roadblock. You can set 100ft, 300ft, 500ft, 1mi,
2mi, or 3mi as a length of roadblock. For example, if you are stuck in traffic
because of a construction site or a car accident ahead of you, you can apply
the relevant distance to roadblock, and the navigation system will make a
detour to avoid that roadblock.
