I tried using the Stop Track function and the unit stopped adding to the current track. It also erased the part of the current track that was there before I selected to Stop Tracking. When set to Start Tracking, the unit started a new current track and did not use any data from the old current track that was made before I set the unit to Stop Tracking. Make sense? So I don’t think that the unit is remembering any trackpoints once you set it to Stop Tracking, but I don’t know if it is still internally tracking or not. That would take the Software Engineer who wrote this part of the program to answer that question.
