When your destination is set and you travel off of the planned route, the system will automatically begin to reroute you. You will see the new route highlighted on the screen.

Traveling Across Regions

If you plan to drive across several states, you may have to change the selected region to represent the area you are traveling to.

There are two ways you can 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 when you get closer to the area you are traveling to. See "Setting the Search Area" under Maps .
  2. Enter your destination and route settings. See Enter Destination for more information.

If you do not want to use the first method, keep your currently selected search area region and enter your destination. This method allows you only to select a destination 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 you are traveling in or to Canada and you cross the regional border, 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 area you are traveling to. See "Setting the Search Area" under Maps for more information.
