Once you have a route planned and begin to travel on
an interstate, a box with a series of icons will appear
in the upper left corner of the screen. These icons
indicate what services are available at the next exit.
A smaller Interstate America icon will appear on the map
next to the referenced exit.
Tracking
Select this option to leave a trail showing where you
have been on the map. Your path will be represented by
bubbles that appear three-dimensional on the screen.
Tracking can be useful for the following reasons:
•
When tracking is activated, you can see where you
have already traveled.
•
When you wish to return to your point of origin
without planning another route, you can follow
the tracking bubbles back to where you started.
•
When you drive into an area with few digitized roads
listed in the DVD database, you can follow the
tracking bubbles back to a digitized area.
To clear the trail left by tracking, turn off Tracking by
pressing the TUNE/SEL knob. This will erase the
bubbles. You may then choose to turn Tracking back
on again, in which case your trail will begin from
your current location.
The maximum length of a tracking trail is
50 miles (80 km). Once you exceed this distance, the
bubbles marking the beginning of your route begin
to disappear as new ones are created at the end of
your trail.
