Take Garmin's popular GPS 120, add the best-selling GPS 45's user-friendly operating system, include a host of new features, and you've got Garmin's newest fixed-mount GPS for mariners. With a large, 4.25" diagonal, three-level backlit display and dedicated zoom keys, the GPS 120XL is an ideal navigation solution for boaters and fishing enthusiasts who want more than a handheld—without the cost, complexity, and large footprint found in typical fixed-mount units.

The GPS 120XL retains many of the same characteristics that made its predecessor the most affordable, full-featured fixed-mount GPS in the marketplace, while updating a host of software enhancements. These include compass navigation in addition to Garmin's customary highway page, an EZinit prompt for quick-and-easy first-time initialization, and TracBack® navigation for retracing your steps without having to manually create waypoints along the way.

For boaters and fishermen who wanted an affordable, effective, and easy-to-use fixed-mount GPS on their boat, the GPS 120 was the perfect choice. Now the GPS 120XL continues this tradition of excellence while maintaining Garmin's commitment to providing consumers with innovative products.
