The files you receive depends on the "PartNumber" tag in the "GarminDevice.xml" file. Changing to a a PartNumber as for example to a nüvi 3790T with "<PartNumber>006-B1101-00</PartNumber><SoftwareVersion>250</SoftwareVersion>" will make the GarminMapDownloader to pick the additional files even for a non compatible Garmin device. nüvi 3790 download gets a larger photo-realistic JCV file that's probably not useful in other JCV capable units.
Hmm... now that's interesting.

I know it's possible to change the XML file with the XML editor and "fool" the garmin servier for registration purposes and the date of the first sat.fix, so I guess you could do the same thing with the part number in the xml file in order to make the server D/L the update that has ALL of the files one may ever need... including the ASR, JCV and others.... correct ?
