Keep the following limitations in mind when sending or creating files for your watch:

1,000 waypoints (saved locations)
30 courses or up to 1.5 MB of total course data
50 points per course
Unlimited points per fit file (limited only by storage space available on the watch)
Ability to add maps unsupported
Connect IQ supported (watch faces, data fields, widgets and apps); Connect IQ apps may fill available internal memory before file limitations are met

GPX files can contain a mixture of waypoints, routes, and tracks. If the GPX file containing a waypoint is deleted, the waypoint will no longer be available on the watch.

When utilizing routes, only 50 points can be used for on road navigation.
