what do you meen by changing the screen. car have a working color display.problem is that i cant see the board computer on the screen(can see only date , time and electrical failures sometimes). BC can be switched on only by switching BC on the original headunit. but i replaced it. how to switch on BC without original headunit? sorry if i have understood wrong something.
I have replaced original stereo ncdr 2011 to a different stereo.original headunit has boardcomputer switch on it. i know that boardcomputer works without headunit. question is, what wires i must connect to get boardcomputer on the display?
