Touchscreen zūmo navigation system with low fuel warning. - Model: Garmin zumo660 - Features: SD music playback - Navigation functions: Map display, route guidance - Operation: Touchscreen This is a set of the zumo660. It includes the main unit and accessories (mostly unused, see images). It also comes with a DVD map software and instruction manual, so you should be able to use it easily. Please ask if you have any questions. The battery is starting to get unreliable, but I used it mounted on my bike with constant power. I have confirmed the basic functions before listing it.
