I sold my old symphony head unit to a guy with a B6 cab, all fitted end entered the code, all worked apart from the radio, wont pick up any signal, even our local radio station,
any reason to why? worked fine in my car,
Just stick a small screwdriver into the aerial socket on the HU. That should allow it to pick up a good FM signal and proves the HU is functional. If that is the case then it's an aerial issue on the B6 cab, either a faulty connection or the aerial amp is not getting any power, although that would normally allow FM reception albeit not brilliant.
