When sending or creating files for an Oregon 450(t) or 550(t), keep in mind the following limitations:

200 GPX files
2,000 waypoints
5,000 geocaches (There is still a limit of 200 GPX files on the device. A pocket query can be used to allow for a maximum of 2,000 Geocaches)
200 routes, 250 points per route
200 saved tracks
2,000 archive tracks¹
10,000 points per track
100 custom map tiles
250 BirdsEye Imagery files
Mapping segments² vary by model:
- Oregon 450, 550: approximately 4,000
- Oregon 450t, 550t: approximately 3,500 (due to internal mapping)

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 device.

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

¹Archive tracks do not count against GPX file limit; 1 archive track per gpx file.
