I have a 98 Passat Estate with Gamma radio (Gamma on cassette flap) and
Sony
CDX-T69 CD changer fitted in the boot. Problem is that although the CD
changer has power (magazine loads and ejects OK), the radio reports "No CD
chnager" when the CD button is pressed - except for this the radio appears
fine. I understand that there will be an adapter somewhere (AVGS003MK2).
At
the radio end this is a blue connector that fills half the upper socket
(of
three) - the CD end has a round connector and two phono-type connectors.
All
look OK. I don't know whether the CD ever worked as the first thing I did
after buying the car was to replace the battery. So,


Has the radio been removed? Perhaps the connections have become loose as a
result?
I'm assuming somewhere in line there will be an adapter, the end at which
it's at is most likely to be behind the radio hidden behind the dash if the
lead at the changer end is a round pinned type (using Sony lead as opposed
to VW lead)
I'd check the lead going from the back of the stereo, my guess is that at
the point where it converts from Sony round pin and phono's there'll be and
adapter, perhaps the connection is loose.

I used to have a similar set up but got rid as there were some functions of
the changer I could not use such as scan and repeat, the vw changer seems
less prone to jumping, but that's just my opinion.
