I ask because I suspect that Garmin has some updating schemes that they just started, that "may" require you to log onto the Garmim server to get an update.. but the server will look for a bonafide GMA file to be present on the GPS unit or SD card before it sends any updates.
I can't say for sure... but it's just a suspicion I have at this time about this GMA file check.
Well, i hope not...brrr! But best to always leave your legit preloaded map only on the unit with its .unl & .gma, and take out the sd containing anything else before updating. That's good practice anyway in my opinion.
