Map Unlock
 

Locking regions of BlueChart® marine cartography allows us to provide you with only the map data you need at a lower cost. If you want to navigate to another offshore area that’s not covered in the region you selected, simply purchase an unlock code for another region at www.garmin.com/unlock/.

Your unlock code is valid for use with 1 Garmin device. A separate unique unlock code is needed for each device you own. If you own more than one device or upgrade to a new device, you will need a separate code for each device. If you own 2 devices, you are allowed a second unlock code for the same BlueChart region for your own personal use at no additional charge. Simply repeat the unlock process for the second device. No more than 2 devices may be unlocked with the purchase of a single unlock code. A new unlock code must be purchased if you have already unlocked 2 devices. Please see our unlock FAQs for more information.
