Hi

You will need to reset your unit - to do this follow this procedure;

1) With unit off - press down with your finger in the lower right corner of screen

2) Keep your finger on the screen and power the unit on. You will see a screen pop up saying "Do you really want to erase all user data"

3) Select yes and then follow the on screen instructions.

4) Your unit will reboot and should now be able to open the maps.

Hope this helps. Please do rate my answer. Many Thanks.

Garmin NUVI 205 when turned on says can't unlock maps!?!


Whenever Garmin Nuvis have map problems, I recommend performing a hard reset of your Gamin Nuvi 205. Also, use Garmin's WebUpdater service to make sure you have the latest software on your device.

I hope that helps.
