I have a Garmin nuvi 40LM and i updated the maps and software via Garmin Express ,it detected my sd card got the option to instal the new updates there , all went smoothly until i started the device again , i get the message " Cannot unlock maps ". Now i search the forums but i did not found the solution for my problem. There were some fixes on the forum but i have no details link under myMaps, if i hover my mouse over it i get the unit ID also i can see my serial number but thats about it no link and unlock code . Please help me , anyideas will be much appreciated.
Thank you.
