How do i get rid of that "locked map when starting up "

Sounds like you did the keygen stuff wrong. put gps serial number in top block, press generate beneath it. Then below that Select Map product, use other, then enter 2281 in empty block press generate below that and paste 25 digit serial into the gmapprom.unl in the GPS. Both gmapprom.img and gmapprom.unl should be in the \garmin (older nuvi)or \garmin\.system directory (37xx) That is all that should be in the file. just the 25 digits you just generated - delete any other data in the file. it must have the same name as the gmapprom.img file except the the suffix is unl instead of img. That should fix your locked map problem.

What is the file "gmapprom.sum" "gmap3d.sum"
can they stay as the are after changing the "gmap3d.img" gmapprom.img ?
