i have 98 one of these myself and my radio was faulty, i got one out of a scrapyard, citroen zx radio's are the same but that soon stopped working. i then just removed the top pocket and fitted a standard radio or cd player the wires in the back of your existing radio are standard fitting so should be simple enough. hope this helps.
ps: is your diesel or petrol, if petrol do you know where the oil coolant is :-)?
