I just bought a Garmin etrex 20 and I've been able to to everything to get it setup (install topo maps, transfer a pocket query) except calibrate the compass. I follow the quick start instructions which tell you to go to Compass>menu button and then to select calibrate compass. When I follow those instructions, the option to calibrate my compass isn't there. The compass doesn't even appear to be working - there is no arrow and it does not move around as I change directions. I'm getting plenty of satellites with good reception.
Anyone have any ideas?
