Hope somebody can help, don't have enough posts yet to PM Chris, so hopefully i can find a solution here.
I have added a rear view camera, and TV tuner via the JDM TV tuner spare input, as outlined on here by Frank350GT, and everything works fine when stopped, so i went looking for the speed input wire for the nav control unit, i found the correct plug and the right pin no, but the wire colour was wrong, manual said B/W but the wire was i think purple and red??
Anyway i sniped it, i also looked for some king of parking brake signal wire to the nav control unit, but i couldn't find anything??
I have tried gently pulling on the parking brake while moving but it still cuts off the screen, i presume due to it thinking there is an error, so it would do no good to just ground the signal wire.
So how do i find the correct wires to snip/ground so i can operate the camera all the time.
Any help appreciated.
