I didn't get a chance to play with them this weekend, but I'll report after I get around to it. There's also the new version 1.12.0 and Bluetooth firmware version1.42.02 that are currently available for download on the Kenwood website.

I thought that was rather odd too, but not knowing much about the programming of these units, I opted to have them both in there. Same goes for the 3D map image file. Even thought the unit was advertised as a 3D map capable, apparent the feature was removed. I saw no difference in having the 3D map image file in my USB stick and not having it. I don't know if the unit selectively copies what it needs (although I doubt it because it copied much quicker without the extra files). Problem is, I haven't figured out how to access the system files to verify exactly what gets installed and what doesn't.

Perhaps this non-Garmin unit just needs to see such file types present regardless of their content during the loading process. If the map being loaded is locked and the files don't match it's FID or the Unit ID then no doubt the unit would display some message like 'Can't unlock/authenticate Maps' on boot-up.

@Neil: I'm think you are mostly right - it just need to see them, as long as the maps are unlocked. When I purchased the 2013.20 map, I loaded it on my unit without issues. When I went to load it on my wife's unit though, it went ahead and loaded and loaded everything. Once it was done though, it reported it was unable to unlock the map and the unit was left with no map to view. Once I replaced the image file with the unlocked 2014.30 map, it loaded and displayed fine on both units, using the same .gma and .unl files from my unit.

Perhaps a .gma and .unl file can be created with random identifier info, if someone care to try that and report.

Given the info provided so far by all of you helping, I'm beginning to suspect there's a hidden and locked directory on these units that do not allow certain files to be modified. An example of this is in the files that Lolypop000 found that make reference to keyboard file, text file traffic provider and time zone image file but these are not seen in the .xml file that the unit loads on the usb stick. If my research (aka my curiosity) drives me to brick my unit, I'll donate its organs to the cause lol!

You were able to load the map on your wifes head unit using the unl and gma file that was created for your own head unit? I might be willing to try if that is the case, I am worried about bricking the unit if the gma and unl are specific to your head unit. I have all the files, but would feel more confident that I will not brick it if you were able to use those files on a different head unit.

Thanks.

The short answer is Yes.

Does anyone know how to read the .gma file? When I open it with notepad, I can read "Garmin GMA" at the beginning and the rest looks like a gibberish cluster of characters. The .unl file is some kind of serial number or key. I used to have an SD card with the older map prior to 2013.20 but I seem to have misplaced it.

jdowney83: Would you mind trying to load the map without those 2 files? If it won't work, it should simply going to report that the map is not compatible and it shouldn't make any changes on your files - at least that was my experience. I'm curious if, since I had them in there when I loaded the map, if it created some type of association.
