That may be easier said than done. Modern cars tend not to have standard
euro sized radios but things shaped and sized to fit the dash, at least on
the outside.

I'd look for an intermittent supply connection fed via the aux position of
the ignition switch, (loose/corroded fuse). There is normally a separate
supply to maintain the memory/code.
