Maybe someone who is familiar with GPS units can help me out here. I have a Garmin GPSMap 60CS. Use it mainly for mapping routes and providing elevation data. I reset the trip odometer and elevation log before each ride. When I return from a ride and download the "track" file off the unit, the data on the track never matches the data on the trip or elevation "page". If my elevation monitor records 2000 ft. typically my "track" file will show 2200 ft., with all the supporting data hills ect. ect. (I am certain the "track" file I am reading only contains the data recorded from that ride.)

Which is the more acurate read? The actual trip elevation indicator, ("page"), or the "track" file downloaded upon completion of the ride?

Any help would be greatly appreciated.
