I have a non Bose 8L S3 and have just bought a second hand Pioneer Avic-F30BT. After reading various posts about what I need to get it going, I think I have everything required. I was just going to test it tonight and fit it properly at the weekend so hooked up a PC9-404 harness (blue connected to bulleted remote on from Pioneer) and a CT27AA05 for the antenna (blue connected to remote on from Pioneer) and switched the yellow and red on Pioneer harness. I was expecting it to come on with that, possibly requiring a manual turn on. I tried swapping the red and yellow back to normal but still nothing.
Head unit and car fuse are both ok. Do I need to piggy back an ignition on from the fuse box even to test it? I thought that was just to tell it to turn on and off with the ignition, so by inverting the red and yellow leads I would at least power the unit on?
