I have a 2014 Ford F150 XLT supercrew with a Kit 150, maestro rr, and a avic-8200ex. The maestro rr is currently flashed with firmware 2.9. I was wondering if I should flash the maestro rr with 3.1 firmware or keep the 2.9 firmware. The maestro rr and the avic-8200nex are working flawlessly with the 2.9 firmware.
