User Data Limitations of Oregon 450(t) or 550(t)
When sending or creating files for an Oregon® 450, 450t, 550, or 550t handheld, 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; 50 points turn-by-turn routing
200 saved tracks
2,000 archive tracks1
10,000 points per track

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 the device.
When utilizing routes, only 50 points can be used for turn-by-turn navigation on roads or trails.
1 Archive tracks do not count against GPX file limit; 1 archive track per gpx file.
