Hi I've had my C4 since December last year and have been looking for a active forum for the C4 since then, glad I've finally found one. I have a couple of questions which I cant find the answer to on the board... 1) Will any standard size head unit fit in the C4 without any modification? 2) While reversing at slow speeds when I brake the rear brakes make a loud noise, kind of sounds like a trumpet, does my head in. Has anybody else had this problem? I've not yet contacted Citroen about it but its driving my mad and is slightly embarrasing :D 3) Has anybody attemped a PC install in thier C4 (e.g - http://www.mp3car.com/vbulletin/showthread...?threadid=75290 )
