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 turn-by-turn navigation, or 250
points for direct navigation.
** Archived tracks do not count against GPX file limit; 1 archive track per gpx
file.
*** Total BaseCamp + Map Manager satellite imagery files. Up to 100
satellite imagery files can be downloaded via Map Manager on the handheld.
