I installed a mobile dvd player and the video is fine,
but I tried installing the fm modulator and it gives a really loud high pitched hum. I tried different setups (at first i thought it was feedback from power inverter i had it connected to, but i also tried other power sources and same thing happens.)
the sound from dvd does work, but that high pitched humm is very loud too.
I've heard of getting a little static, but this is not that, it's pretty loud and steady. is it the radio causing this?
it's a sony deck that is connected to a cd changer, (the cd changer is made for the radio).
any way i could by pass something? maybe the switch to the fm modulator?

Where is the horn that was blowing? They have passed like rain on the mountains. Like wind in the meadow. The days have gone down in the west. Behind the hills, into shadow. How did it come to this?
oh, i should of told you guys,
I don't know which is a power 12v for the radio, so all i tried was a power inverter in my car and the other source was direct to the battery.
the ground i'm using is similar to my video monitor which works fine, but maybe i should try another ground too?
but ground makes it either work, or not work at all, right?

Does the FM modulator that you have need to be grounded ? If so make sure that the ground is solid and on a surface that is paint free & dirt free.
