Anybody know the specifics of the protocol between the keyboard and the navi unit?
From the service manual it seems to be a serial protocol differential differential input output with 0==0V and 1==5V (RS422? or RS485?).
Does anybody have some specs?
Does anybody know if it is bidirectional?
Thanks.
