I know this is going to sound like a dumb question but I am having the hardest time trying to get maps on my Garmin c330. I have 2GB SD card and was able to get the file gmapsupp.img on to the card in the garmin directory. I got the maps on the SD card through MapSource's option of "Send to Device". I've used the v1.3 keygen from this post and made the gmapsupp.unl and sw.unl files and put them in the garmin folder on the SD card too, but when I put the card in the GPS it keeps saying "Can't Unlock Maps". I upgraded to the newest fireware (5.70). I also got City Navigator North America NT 2008 from TPB. I've read the comments and a few different methods to get this working and none have worked so far. I tried using the SD Card ID number (in a hidden menu on the GPS) instead of the Unit ID in the keygen. I've tried changing the unlock code in the gmapsupp.img file with a hex editor. None of it works. I've tried simple and I've tried hard. Anyone have any idea what I'm missing?? Any help would be appreciated!!
