Hey, so I was trying to decode what kind of files should I update, what kind of them are supported on my device. All I know is that it is Garmin for automotive.
What I am struggling with is:
What kind of JCV files are supported, becuase I installed some "random" ones and can't tell that they are working.
What should be gmapprom, and gmapsupp?
Can I tell somehow what kind of Garmin navi model ...
