I have a 1996 Vectra with factory-fitted Philips CAR400 radio-cassette(ISO).
I've added a Blaupunkt 4x25w amp but now I'd like to install a CD/MP3 tuner
as well(still need access to the tapes at the moment). My question is: is it
possible to "cascade" the radio-cassette with the CD/MP3 tuner via a
splitter cable or similar? I've looked at buying a CD unit with an aux in
input at the front(was thinking of connecting a walkman there) but they all
seem a bit pricey.

Jim.
