    I have my phone connected to my aux input in my car. Works great. However, if I plug in the car charger, there is a loud hum coming though the car speakers. I have tried a different charger but the same results.

    Has anyone run into this before? Wondering if there is a filter is could get to eliminate the noise. Thanks.

    Is your stereo grounded correctly? I have no problems using mine. Hooked up to my eclipse with one of the newer pioneer radios. Also check your ground where your cigarette lighter hook up is. Wish I knew more to help you.

    Is there any hum when just using the cat charger and not hooking it up through auxillary?

    Thanks for the reply. I assume it is grounded correctly, it is the factory radio in the car. How would I check the ground?

    No, if I don't have a cable plugged into my phone, I don't hear the hum.

    It may be your auxillary cord. Although if two of you have the problem then its likely interference. You would need a filter between your phone and the unit. I have never needed it so I couldn't tell you which one. Goodluck guys

    Does it have the noise if the device plugged into the aux jack is being powered by a car charger?

    Hmm, sounds like there is a problem with the stereo. This isn't too expensive. You might try it to see if it solves the problem:

    It could be that the radio input is a "floating" ground, which means that it is the ground in the radio circuitry but not connected to the car's ground. Is it actually a hum or is it a whine that varies in pitch with the engine speed?
