Can anyone advise on a problem that I have got with the Alpine head unit in my 156. It is the standard head unit supplied by Alfa in their pre 2001 cars. It has worked flawlessly until recently when it refused to play a cassette - it clunked a lot and then tried to re-wind it, back and forth. I tried it several times with the same results, but when I took the tape out and put another one in and it worked fine so I asumed it to be the cassette that was at fault. I later swapped cassettes again. This time it loaded, clunked a few times and then spat out reporting "no tape". It now does this on all cassettes including the one that had worked previously, and a head cleaner.
The radio/CDs play fine.
Any suggestions as to whether this is a user fixable problem, an engineer fixable problem, or a sling-it-in-the-bin type problem. Any comments gratefully received as my son is missing his nursery rhym tapes!!
