I think what you are asking is the step by step for getting the entire locked image in Post 1 into your GPS? D/l the image. uncompress it. rename it to gmapprom.img if different. Hook up the gps using a usb cable. using Explorer or some other File Manager to get to the 8xx gps \garmin sub dir or 37xx .system directory. Copy the gmapprom.img on your GPS to somewhere on your computer hard drive so you have a back up copy of it. Once copied, then copy the new gmapprom.img you uncompressed back to the 8xx GPS \garmin directory or 37xx .system directory. It will ask to overwrite. Tell it yes. Once the file is copied to your gps, use a text editor like notepad to create "gmapprom.unl", an empty file on your PC. Then, using jm keygen v1.5, enter your GPS Serial Number in the top block, press Generate block midway down, then drop down to next block where it asks for what map, go to bottom map name drop down block, and hit "other", a block pops up and then you enter 2281 into this block (this mapset ID), hit enter, press generate block near bottom, copy and paste the serial number from the very bottom block into the gmapprom.unl file on your PC Copy this file to the same place you sent the new gmapprom.img file on your GPS. Done. Disconnect GPS safely. Map should now be unlocked and function OK when you turn GPS on. If all is well, map comes up meaning it is successfully unlocked, then try using voice command to Find Address. If GPS says locked map when starting up, then redo the key gen steps.. you entered incorrect serial or map id... If Find Address gives an error, then there are errors to look at like incorrect ASR files, and other things that seem to go wrong with these voice units.

Hi,
GPS says locked map when starting up. But the map is working and loaded . In the screen Info from the Map i have "City Navigator Europe NT 2011.30"
I have it installed as "gmapprom.img". I have the updated Unl file. Do i have to claen up the previous serial number in the Unl file ?
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.

thanks Vincent
