Hey there!

I would like to know is there a way to revert the firmware and/or software on the MK3 unit? It seems the previous owner has in a way bricked the unit, becuse the Service Mode is in basic mode (only 2 choices) and no GPS selection on the screen, even though the unit is in the back and seems to be working.

I can't even identify which firmware version i have, as it doesn't show it anywhere in the Service Mode (upper right corner usually), but i read that 3-1/32 should be the best fit for MK3 unit. Does anyone have a link for this FW?

Thanks for helping me out!
