Hacking Blaupaunkt CAN Interface RCI-4A interface
i have a 2005 Golf Mk5 which uses CAN bus for just about everything.
so in order to integrate with the carpc better, i purchased a Blaupunkt CAN Bus interface RCI-4A-VW in an attempt to hack out the Acc, Illuminiation, reverse & speed pulse signal.
everything works as plan except for the illumination signal. the strange thing is that it seemed to be a pulse signal at 1kHz and it doesn't work with my car pc as a result. i know i can just pull a illumination line from the ashtray light, but i really hate lose ends.
anyone has any idea?
