I love my 62st, ya I know the "t" is basically worthless and not worth the added cost. The only problem, or irritant I have with mine, is if you do not save and turn off tracking before you shut it off, the next time you turn it on you will have straight track lines going from where you turned it off to where you turned it back on again.
In my case they went from Puyallup to Trout Lake to Winthrop, back to Puyallup, over to Wynoochie, and back to Puyallup.

I did not realize it would do this until I uploaded all my tracks into Base Map.
There are tons of people complaining about this on the Garmin forums (this affects all Garmins with the new software load)
To resolve this, turn off tracking before you shut down, then remember to turn tracking back on when you start it back up.
