Hi there,

I've recently bought a 1998 Passat with Gamma head unit and boot
changer.

The documentation with the car has a correct CD-changer supplement,
but the main "Sound System Gamma" manual appears to be for a different
model than the one in the car!

I can't seem to switch the head unit to CD. It will happily select AM,
FM and CC (compact cassette) but pressing the CD selection button out
of the 4 does nothing.

Sounds like the CD button is broken as there should be some display
response, TIM is Traffic Information Memory which records RDS travel reports
while the ignition is switched off.
