500 custom map tiles
250 BirdsEye Imagery files
15,000 mapping segments
Each GPX file can contain a mixture of waypoints,
geocaches, routes and tracks.
If the GPX file containing a waypoint or geocache is deleted, the waypoint will
no longer be available on the device.
When utilizing routes, only 50 points can be used for on road navigation, or 250
points for direct navigation.
*Archived tracks do not count against GPX file limit; 1 archive track per gpx
file.
