Finally figured out how to unzip the 21.9 file, have to use 7zip and open the archive to then unzip it, anyway now trying to reload the maps but cannot get the radio to react. Anyone else find a way to reload the map files after losing them during an upgrade? I am at the 39.6 version currently and trying to downgrade to the 39.5 with the 21.9 maps it errored out with 01.
There really should be more mentions about UAQ upgraders to add map files surprised no one really talks about it. Given how the AA works 50% of the time whether its the device not supported or simply doesn't acknowledge the plugged in (dozens of cords and 10 different hubs, still same) I need the nav as a backup, I drive all over the East coast and better part of the country regularly so nav is very important.
