My Garmin GPS 12 has a field on the main position page that can be set to
Trip distance, Average speed, Max speed or Elapsed time and another which
has Altitude, Trip time, Elapsed time or Trip distance. I keep them set
to Trip distance and Altitude.
The accuracy of altitude is generally about a half that of position or
distance, if the EPE on the satellite page is 10m altitude will be ~±20m.
We discussed this in February in the thread 'Ping: Tom Tom One Users'.
