Okay, I checked drdru76's method of reinstalling everything from scratch and everything should really be 100% okay only the XXL hangs at startup displaying the startup image.
I know it's no guarantee but the map works in TTH which at least proves that the activation has succeeded. Ttgo.bif shows the map and map shares are downloaded.
I sent him the BNL map (which I know is okay) and it's the same thing with that map.
The drive has been checked for errors and clear flash has been run several times.
Honestly, I can not think of any reason for the device not starting up correctly.
Last thing I suggested was (
click) was to remove the currentmap and position which TTH had created and restart the XXL then.
I'm out of idea's...
