New reciever buzzes

[CGlasel]

I just installed a Dual XDM6830 stereo headunit in my 2003 3500. I wanted a hook up for my iPod, and the factory unit was eating CDs.



So the Dual is great except that there is a high pitched humm or buzz while using FM. Engine running or not. Crutchfield replaced the unit and the new one does it too.



Any thoughts? When I unplug the FM antenna the buzz seems to go away, but so does FM reception.

Find a Ham / Short Wave radio shop in your area , they should be able to fix you up with the right filter , how about parking truck in a different spot , with the engine not running , it shouldn't be the truck , its best to fix the source of the issue if you can .
