Hi,
New to the forum so hopefully someone can help me, I've an audi a4 s line 2005 model. love the car and never change for anything. anyway cutting a long story short my audi concert cd radio was draining my battery. when i turned off car and locked it there was a faint buzzing coming from my speakers. i went to an electrics guy and he told me the problem was with the radio or the steering wheel controls. anyway i sorted the draining problem by disconnecting the connecter D( reading "tel mute, tel+, -nf, nav +, -nf, and nav. con etc) from back of stereo. this stopped the battery drain but now ive no telephone or sat nav. it's still reading the phone through bluetooth but i can't talk through my speakers, the nav is also working but the same thing, it won't talk through the speakers. the electrics guy told me to get a new radio and i would if i knew for definitly it would sort the problem. just wondering can anyone help me on this problem as i'm lost without my phone

Thanks,
upset Philip
