When I hook my DROID up in my car using just the headphone jack to my cars AUX jack things work fine. Once I also connect the vehicle charger I start to hear engine noise. The noise increases in frequency as I rev the engine.
How do I resolve this issue? Is this a grounding issue in the car? If so, how would I get them to fix it since the car is under full warranty.
Do I get a DC power filter, a different brand car charger, a audio cable with a Ferrite core? I love using my DROID to play music using either the built-in MP3 player or Pandora, but on long car trips this becomes an issue.
I am open to suggestions and look forward to your responses.
Thank you in advance!
