I've had mine since it was first introduced. Love it for driving. It's a little complicated to transfer cache files, you have to convert them first. The biggest dissapointment is that there are still no topo maps availabe and the topo basemap is not adequately detailed. Also, it's really not waterproof enough for serious trail or marine use. If you put it in a dry box it's bulky and you can't operate the touchscreen. Other than that it's great:) Seriously, had I not purchased it I would never have known how much I would use a streets GPS.
