Hi all,

I finally managed to fix the interior lights on my Passat at the weekend -
problem was the joins on some of the cables from the CCM had corroded
(inside the tape covering vw had put on, so problem wasn't immediately
visible). So thanks to everyone who pointed to where the problem had to
be.

However, my radio problems (only receiving very strong signals, no power
to
CD changer) remain.

I've got the head unit out (VW Gamma (Blaupunkt version)) - can anyone
confirm that the antenna amplifier is powered via the coax antenna cable?
Should I expect to see any significant voltage on the radio's antenna
input
(I don't)? If not where is the antenna amp powered from? The pin outs for
the Gamma radio are shown he

I have got 12v going out to the CD changer, so the problem there must be
with the adapter/cabling (it's a Sony CD changer), but it's a bit of a
co-incidence that both problems occurred at the same time.

cheers

If it's only receiving strong signals, then the most likely thing is that
the antenna is not powered. Yes, it does get a phantom supply on the co-ax.
If the radio is not supplying this then you can get an adapter from places
like Halfords which goes in the co-ax line, and you connect a source of 12v
to it.
Can't help on the CD player, but it sounds like an interface problem.
