C4 Headunit

[Greggors91VTS]

My sister has a c4, and the radio keeps on changing between FM stations by itself, I have heard it is a coommon thing in c4's. is there an easy fix? Would it fix it if i put my old c2 head unit in it?

I think the C2 mk2 and the C4 headunits are the same mate, couldnt hurt to try, you will see if it will fit straight away by the lead on the back but remeber you may need it re-coding
