following with interest- I have the same headinut in my estima hybrid G (2010). have just had some irregular issues with audio popping and seemingly muting the headunit. also lost feed do the roof screen in the rear, but that's back now. I notice what I assume is two amps under the passenger seat, one sat on top of the auto park computer. I've disconnected the teletry plug and the TV antenna as they dont serve any use to me. I don't suppose anyone has come across a wiring extension plug for the 10 pin aux plug? I'd much rather splice into a removable cable than the original if I can. Like Pillarama I'm installing a Raspi, but just want the audio feed, will put an additional screen infront of the steering wheel for carplay.
