In Sept I fitted a Sont Mp3 Head Unit to my 53cc. No probs other than strereo controls by steering wheel no longer worked.
I have recently had new speakers fitted and a 'Stalk' lead installed to enable me to use controls again.
Major Problem - my head unit is now draining my batery and unless I use cc every day for a long period it drains the battery. HELP!! I have had to take out the HU untill I can get car booked in.
