Garmins are notoriously glitchy

I've had several - they've all done weird stuff at times. In particular, the thermometers can be really rubbish on them (but who cares about that, really...)

try logging on to Garmin Connect and checking for system updates though, if you haven't recently. Sometimes make a difference.

As for the heart rate - mine does similar. Just the act of riding on the road takes one's heart rate right up. 120 is completely 'normal' for casual road riding (though everyone is different on that score, of course). I wouldn't worry, anyway.
