On my first road trip with my new Droid I eagerly hooked up an 1/8" stereo cable between my Droid and car stereo with great results. Then I plugged in my car charger (brand new "RocketFish" from Best Buy) and there is a ton of audio interference. As I rev the engine of my car there is a high-pitched whine that is almost the same pitch as the RPM's of the engine. Has anyone else with a RocketFish car charger have the same problem? Has anyone else had this problem with an official Verizon car charger? Has anyone else had this problem at all? Thanks!
