Ford Fiesta Rsd 4500 Replacement

[gwilym]

Hi, My 4500 RSD radio in my fiesta mk 6 2002, has gone T*ts up and won't hold a channel (keeps searching on FM) so I want to replace the unit with a 'normal' radio with bluetooth etc. The garage here in Spain has quoted me €85 just for the fitting and making good.

Can anyome advise me if I can do this myself and if so, how and what parts do i need.

Thanks in anticipation
