Backroadmapbooks uses Garmin License technology to unlock and display the maps on your unit.The license files are used to unlock the maps on your device and can also be used to unlock the maps you have installed in Garmin Basecamp.
Currently the unlock code is produced by providing Garmin with the unit serial number along with the map product's registration or coupon code. I've never understood why they didn't just use the serial number of the map product instead having a separate registration code. Get the latest street maps and points of interest for all Garmin product categories: automotive, golf, marine, aviation, outdoor and cycling.
