These modern marvels track the car's position using the Global Positioning Satellite system and digital maps in the unit's memory, and provide directions to the driver to get to their pre-established destination. Given the fairly steep price of these units, and the variation in features and quality, ratings will be helpful for those making a purchase for that directional-challenged driver in their family! This list includes OEM and after-market auto and motorcycle mounted units, but NOT handheld or marine units which are covered in a separate list. Please feel free to add units to this list, which is not comprehensive.
