When I am talking on the handsfree, I hear a low whinning that follows the engine. The dealer said they did the fix :-( i think it is whinning the same if not more. I have tried two different phones and carriers. Any Ideas?

it works work for me fine

 

its interference from the alternator, the dealer should check the grounds and wires for the HFL unit

 

is this bad for any components? mine does it also but I'd rather deal with it then let the dealer touch my car.........

 

The audio system is stock. The dealer is telling me that this does not reproduce and next time they need my phone.
