This tiny keychain Mini Roadmaster is a bare bones GPS navigation device which makes no pretensions to being a full mapping system. Instead you get a basic but useful voice navigation system which will guide you to a nearby point of interest that you need, like a gas station, restaurant, or hotel. It also offers a simple city to city navigation service, but it’s not going to replace Garmin or Tom Tom any time soon. But then again look at the price! $12.97.
Just select the closest highway exit or mile marker and this talking keychain tells you the closest gas station, restaurant, rest area and more. Also recites city to city directions and travel phone numbers (motels, airlines, car rental and road help). An invaluable resource to have on hand all the time!
