    Thumbs down Cannout Authenticate Maps

    I'm trying to install Europe 2011 maps to my nuvi 3790t. I unlocked the maps with jetmouse keygen, and checked that the maps are unlocked in mapsource.

    But when I transfer them to my device i get the message "Cannot Authenticate Maps"

    I've read something about unpluging the gps instead of ejecting it after the transfer is completed, but it didnt work...
    I can see the file (gmapsupp.imb) in my Map directory, and i dont have a .unl file, but i understood that if I unlocked the maps in mapsource there is no need to have one.

    Any hint?

    Thanks in advance, great site!

    Excellent!!!
    I missed the final step, to unlock the map generated by mapsource, the gmapsupp.img, with the fast img unlocker.
    I used the version 1.7, it unlocked the map inmediately.
