11) Preview a route (starting from a different location)
It is possible to preview a route that starts from somewhere besides your current location. For
example maybe in a couple days you will be traveling from Nashville to Chicago, but your are
not in Nashville right now. You can tell the 7700 PRO to start from Nashville.
1. Enter the destination address as you normally would, and then tap on ROUTE OPTION
2. Tap on CHANGE START POSITION
3. Now enter the starting address and then let your unit calculate a route.
