what cables did you need to change from factory to your headhunt, Ive got a Sony head unit. Halford want 30quid, Im damn sure the cables will be about 3quid on eBay lol
@George Websdale no. The mpg info stays the same. I just had a new head unit installed. Halfords ripped me off though. Aparently u can change the settings via the control stick on the steering wheel by pressing the top and bottom shoulder buttons simultaneously but mine didnt work
