I've got the head unit from my dad's A4 out of the car, and on a bench for inspection and repair (of cd playing problems). Got a 12V 5A DC power supply feeding it, it turns on, SAFE is displayed, I enter the code correctly and the display switches to display bands and station numbers only for a split second.
The unit then dies, and needs powering up again and the process repeating.
The pinout diagram shows a K BUS pin, does this need to be connected to the car? If not, what am I doing wrong??
Thanks for looking, and hopefully you can provide some help!!
