2017 accord I had body work done incl attempted radio replace. New radio was w/gps no good (car did not originally have GPS)cannibalized touch screen and screen motherboard... nogo. Replaced original radio now get message “audio power off” (on upper lcd) radio will not start, lower lcd is blackout, car will not lock w/w/o fob (interestingly it will unlock w/fob & trunk works) seat memory gone and auto start not working. Radio and BU fuses are fine, no message re radio code. Really freakin baffled
ALSO battery died due to -27degrees->fuel froze in line 2 days prior to going to body shop
