Recently bought a 11 year old TT, lovely car but came with the Concert Cassette player, found a second hand Concert CD player model 4B0 035 186G. Had this fitted by professional car-audio company who at the same time added Ipod interface. Ipod works fine but CD unit only powered rear speakers, after a while decided would prefer all speakers and could just use ipod racther than CDs, but cassette player does not recognise Ipod.

Any thoughts wher I go from here, either CD unit with all speakers or cassette with Ipod!
