I have a Drive + Play hooked up in my car. The power source is hardwired into the car, and when I had the power adapter plugged into the cig lighter it still made the same sound. My head unit does not have an aux jack, so I bought the drive + play fm modulator. When I tune the unit to the fm freq I want I get a constant buzzing sound on every station I tune too. Any suggestions?

what you are experiencing is a feedback from the ignition of the car.
check your ground wires really good, and try a few diffrent locations.
this could also be the engine/chasis ground wire.
hmm ok. What should I move? The ground, or the actual brain of the harmon kardon?

you need to check the ground wire between the engine and the chasis.
also try a spot or 2 on the location of your harmon kardon ground.
