Garmin Nuvi 65LMT "Can't Unlock Maps"

Former Member

I am using my device after a long time and the last time i used everything was working as it should. I have 3 maps on my memory card out of which one map results in an error "cant unlock maps" upon booting the device. This is the map for UK. I installed Basecamp which shows all the maps on the device and on memory card without any problem. When i goto Map - Manage Map Products", it shows all the maps with the one i have a problem with as "unlockable". I dont know what the problem is. All was well, the last time I used it. I tried updating Garmin express but no luck.
  • If you've purchased the map for that device you don't need any unlock as it will come with the necessary file. How did you get the map?

    Hi. I have purchased this unit second hand, which came with all the maps .AUS/NZ, US north on the device and Europe, Middle east on the memory card. I am giving up on this issue and decided to buy the maps. I am using NUVI 65. I see maps with the suffix it NT and NTU. What is the difference? Are they both compatible with my device? Thank you for all the help
  • Your device would normally use the NTU version.
