There are numerous rising cases of users willing to figure out a method for unlocking a PIN requiring Garmin Nuvi.
Although there are countless methods described over the internet, most of them won’t succeed, thus it’s about time to provide an actual, fully working unlock process for a Garmin Nuvi that’s locked with a PIN code.
The only method to unlock the gps is also the one offered through official channels and it requires you to be the real owner of the device.
You will have to provide an acquisition receipt or invoice for the device you want to unlock, and then you will be guided on how to unlock the PIN locked gps.
If you can’ provide an acquisition proof of your Garmin Nuvi, there is virtually no other possibility to unlock the navigation system. No reset methods works and no update attempt will solve the issue. The reason this happens is that Garmin assumes you have come across the device in illegal ways, since you don’t own any justifying documents.
If you can prove yourself as the rightful owner of a PIN locked device, the situation will resolve; otherwise, you will have to acquire a different navigation system.
