I have 90 Multivan with AM/FM Cassette standard VW factory setup for this
year.  It plays cassettes tape without any problems but I lost my radio
function.  What I have discovered is when I press the eject button all the
way in and hold this button in the radio will come on.  There must be some
internal switch that is malfunctioning.  The way the system is setup is
when the radio is on and you insert a tape the radio automatically shuts
off and the tape plays, when you eject the tape the radio automatically
comes on.

Questions--does anyone fix these things?  Are factory radios available and
any idea how much?
