Mercedes Benz problem with AUDIO 20
Hello everyone,

I am looking for help because i have a problem with my car (Mercedes W212 E class with AUDIO 20 NTG5 ). After I updated the original SD card Garmin Map Pilot to the latest version, I put it in the audio system and after I turned on the navigation, a message "Cannot Unlock Maps" appeared. I tried different SD cards but the error still appeared. When I ignore the message and turn on the navigation no maps appear and the navigation can't be used. I tested the car with XDOS 07.2017 and SD C4. The error in the photo below cannot be deleted. Can someone offer any help, I would be very thankful?
