One big thing I use my moto droid for is pandora or last.fm in my car and use a radio with an auxiliary input. But i started to get a lot of feedback and the feedback would get louder as i accelerated...i started trying to figure it out by changing wires turning wires..and came accross its when i have my droid pluged in charging and pluged into the radio..so im assuming the car electricity is going through the phone and into the aux output.. is there anything i can do to prevent this because i want a clean sound and the feedback is extremely annoying...any tips will be greatly appriciated. Should i try a different car charger? i use a usb-microusb then plug it into a usb-car adapter. thanks!!!!
