Catmag:

Thank you so much for your very fast respond. Actually I already ran a GARMINUNLOCKER.EXE and it said unlocked successfully.... also, i make a file call GMAPSUPP.UNL with the unlock code already but still could not get it going.

here is what i have:

1. Garmin Nuvi 200W
2. GMAPSUPP.IMG ........I just copy this file to my garmin nuvi inside GARMIN directory.......... file size of 9.73MB ...... this is for Cambodia
3. I put this file the same directory of the GMAPROM.IMG because it has enough room for it.
4. when i reboot the unit, i saw the Green bar ran from left to right seem it load the map... but after i press accept... the message was : "CAN'T UNLOCK MAPS"
5. I also used the Jetmouse to get the unlock code ..... and i made a file called GMAPSUPP.UNL with the code inside this file.

what else do you recomment me to do?

I have not try this new software you gave me yet.... I will do this when i get home today.

thanks so much for your help.
