I purchased "Garmin City Navigator Europe NT" for my new Garmin nuvi 2597.
However after installing the SD-Card into my device and turning it on,
it displays "Cannot unlock maps"
"Maps are corrupted and cannot be used. Go to www.garmin.com/express to download the latest maps."
I've installed all possible updates by Garmin Express,
but yet the above messages still appear and the device don't recognize the European maps at all.
Garmin Express don't even show the European maps.
I need those maps really urgently.
Please help.
What can I do in order to resolve it ???
