If you have purchased a prior copy of our Western Canada Grid Map this update is available free of charge. If you have bought the previous version of our map without the BC NTS grid it will not unlock for you, however you can buy an update for $99 from us our one of our retailers.
To install the new map, simply download and unzip this file and place it in the Garmin folder on your SD card. It will replace the existing file and will have the entire BC NTS grid as well as a more detailed road grid and Points of Interest Database.
