Help ! concert h/unit in b7 avant.
I'll try to be brief .My avant was (still is) fitted with a symphont h/unit and disc changer is kput so I got a concert h/unit with code of fleabay which came with the quadlock loom. Now everything appears wired correctly (non bose sys) but when in unit refuses to switch on so I can input the code.so is the head unit knacked or am I missing something,does something need changing/recoding in the vacom for it to power up or have I bought a duff.HELP !
P.S I have sorted the different aerial connecters with the help of audi dealer and srapyard.new double fakra block from dealer and an iso to fakra adapter from the scrapyard just need to know if they should fit a certain way round.:uhm:
