when you approach or reach your destination.
If you deviate from your course
The unit notifies you with an alarm and the course deviation indicator. The GPS
key's light flashes green and red if you deviate from your course. The indicator gives
you the information of the direction you are travelling in (track) versus the direction
to your destination (course) so that you can check if you are heading in the right
direction. This information is called "cross track error."

(see table on the right).
