Hi guys
I've just purchased an audie a4 1.9 tdi sport avant and want to change the head unit to my sony bt unit and have bought the pc9-404 and the 410 cable came with it from halfords as I have rear amp but when I removed the concert stereo I noticed two lots of brown and black connectors on the loom which looked like a loop if that makes sense but unplugged the set from the back of the concert and plugged them into the pc9-404 and am getting no power to the sony head unit as I thought the pc9-404 should be plug and play but have notice a red wire (ignition) wire coming out of the new iso connector.
Any ideas guys?
Many thanks max
