Unlocking Maps in Garmin Basecamp [PC]

If you skipped the .gma file during the initial map installation, you can manually import it to activate the maps. 
 
 
 1. Download the .GMA Unlock Key 
 
 
 
 Source 
 Where to Find It 
 
 
 
 
 From a device 
 Insert your microSD card → open the Garmin folder on the card → locate the .gma file (e.g., gmapsupp.gma ). 
 
 
 From your account 
 Log in to your Backroad MapBooks portal → download the .gma file you received during purchase. 
 
 
 
 
 
 
 
 2. Launch Basecamp 
 
 Start Garmin Basecamp . 
 If Basecamp detects any locked maps, a dialog will appear automatically.
 
 Click Unlock maps to begin the process.

 If the dialog does not appear: 
 Open the Map Manager manually: 
 Maps → Manage Map Products in the menu. 
 
 
 
 3. Import the .gma File 
 
 
 In the Map Product Manager window, click the Unlock Regions tab (top‑left). 
 
 
 
 Click Import . 
 
 A file‑open dialog appears. 
 At the bottom right, change the filter from .ucx to .gma . 
 
 
 
 
 Navigate to the .gma file: 
 
 If you keep the key on your microSD card, browse to E:\Garmin\ (or whichever drive letter your card is assigned). 
 If you downloaded the key, go to the folder where you saved it. 
 
 
 
 
 Select the file and click Open . 
 
 
 Verify success – the map entry should now show something like “Region unlock code from …” next to its name. 
 
 
 
 
 4. Refresh Basecamp 
 
 Restart Garmin Basecamp. 
 From the Maps menu, choose Backroadmapbooks to load the newly unlocked maps.
