Murv

Hi All, I'm a new member with a C4 2007 hatch. I want to fit an aux input, I've found a lead which I believe is fine and will work. I understand for the RD4 stereo to recognise the aux input, it needs to enable via Citroen diagnostics software. Is there a member out there in Leicester area who could activate the stereo for me? Regards, Jas
