As with most people who have one, I just use my Garmin 205 to record the race or training run (especially good after night runs to see where I actually went). Wouldn't really want to use it for navigation - what would be the fun in that?, although I must admit to using it a couple of times in the clag during an O event yesterday to estimate distances run, e.g., I expect to come across a stream in 1/4 mile.
Mostly actively use it during road races for pacing.
