Bought the 67i last week. Been playing around with it for a bit, kinda wonky interface. Seems buggy to me. Did all the updates I could but still buggy.
Kept having to do hard resets to clear out old/incorrect navigation points. First hard reset where I held the power button for 15-30 seconds seemed ok, but then I did another one a few minutes later and now device is totally dead. Won't turn on, won't charge, can't connect to USB.
So far my whole experience with my first Garmin device is pretty sour. Guessing I'll have to get a warranty replacement.. Fingers crossed the next one isn't such a disaster!!
