Preventing Mapsource or BaseCamp From Truncating a Track
Outdoor GPS devices can accept tracks that are saved and/or created from either MapSource® or BaseCamp™ software. The tracks will transfer exactly how they are created in the mapping program unless the track is over 500 points. Once the track is over 500 track points, the device will truncate the track. In other words, the device will condense the track below the 500 point limit.
If you would like to send over a track that is over 500 points and do not want it truncated, then rename the track ACTIVE LOG in the mapping program. Right-click on the track name and choose Properties to rename. The Properties field will also show you the number of track points.
This will upload the track to the current track log instead of as a saved track. Ensure the current track is cleared out before sending the newly renamed track.
