Garmin - StreetPilot c330 GPS Receiver —
The Garmin StreetPilot c330 GPS receiver is an economical and portable. It tells you when to turn and in which direction, but doesn't name the street. It has an SD memory slot which allows you to install additional maps or new waypoints. The biggest problem with this GPS is that the suction cup doesn't stay attached to the windshield for more than an hour or two before it comes unstuck. The dashboard attachment disk (a smooth disk with an adhesive backing) did not stick to the dash at all.
