not sure if thats hr wright word, but when ever my iphone is linked to car i can here a winding up noise through the speakers when i get on the gas.anyone have this prob.cheers

 

Otherwise known as alternator whine due to poor grounding somewhere in the system. Sometimes here it when phone is charging through a cigarette lighter adapter.

 

yep thats the noise reminds me of when i hooked up old stereos in my first cars lol.i have only had the car about a week and it never seemed to do before it just started .and its never plugged in for charging

 

Yes, it just started to happen on mine as well.
Previously , no problem. Could it be the cold weather?
Now when I plug my iphone in and play either music or mini connected is saying something, I hear it.
Grrrrrr!
Any solutions?

 

Well i took my car in to dealer back in December and of course they couldn't hear anything.Finally had great weather today and took the car out and its making that noise still. So i turned my bluetooth of on my phone and turned the stereo of and its still there. When i accelerate it get a little louder....? guess its going back to dealer.....

 

Is your girlfriend in car? Excellent source of hiss.
