I downloaded an update that added navigation for it too.
Garmin's GPS is way better than it however.
I went outside on the porch and it took about 5 minutes to lock on and get a GPS signal. Too long in my opinion. My wife's phone and our older garmin GPS get a signal in about a minute.
Another thing I don't like but can live with as it's not a huge deal, but the usb connection is not the regular mini usb but instead a micro usb connection so I can't just use any of the many usb cables I have laying around.
Micro is on the left and the mini connection is on the right like the phone uses for it's charger.
