Have a 98 Ghia X. Get ERROR 5 on head unit and it looks like CD is stuck in the multichanger If the changer is U/S any ideas on cost effetcive replacement which keeps as much of the original stuff like speakers and more importantly the remote control on the steering wheel. I'm not sure what's behind the original unit, perhaps there is a separate amp, if so, can I get another head unit and plug it straight in Not bothered about replacing autochanger, single CD input at the front is more convinient. Thanks for yor help Jim
