Auto Reroute

When the destination is set and you travel off of the planned route, the system automatically begins to reroute. The new route highlights on the screen.

Traveling Across Regions

If driving across several states, the selected region might have to be changed to represent the destination.

There are two ways to plan a destination when traveling across regions.

The following method is suggested and provides the most route guidance and map display functions:

  1. Change the selected search area region as you get closer to the destination. See "Setting the Search Area" under Maps.
  2. Enter the destination and route settings. See Enter Destination for more information.

If not using the first method, keep the currently selected search area region and enter the destination. This method allows a destination selection from the easy planning route method or from the All Points of Interest (POI) categories with the "All Search Areas" comment for US Only. For example, Tourist is a category that features this comment. See Enter Destination for more information.

If traveling in or to Canada and the regional border is crossed, the only map scale views available are 4 mi, 8 mi, 31 mi, and 128 mi (8 km, 16 km, 64 km and 256 km). Change the selected search area region when you get closer to the destination. See "Setting the Search Area" under Maps for more information.
