GPSDrive *never* displays the altitude.  It always displays "n/a" in
this area.

The GPS itself is a Garmin GPSMap 60 CSx which has a barometric
altimeter, can see 10 satellites at the time and is itself displaying
altitude and '3D' in it's own status.

Here is a sample from connecting to gpsd now.
