I installed City Navigator Europe 2015.20 ( FID 3466) and unlocked it in MapSource using Unlock MapSource Directory. Then, after selecting map set, I transferred it to my Nuvi 660. I assume, that since maps are unlocked in MapSource, there is no need for unl file. MapSource said that transfer completed successfully, but when I turn on my nuvi, it says 'can't unlock map' .
Any help will be appreciated, thanks.
Just my two pence.
1. City Navigator Europe 2015.20 ( FID 3466) present now in Unicode version only and this version is fully not compatible with Nuvi 660!
2. Nuvi 660 have a very obsolete SW and it do not know about gma. Garmin have a loyalty program for owners of oldies
