backup video makes am noisy

2009 Kia Rondo Pioneer AVIC X710BT Boyo VTL351 Camera PAC SWI-PS Remote Interface Hooked everything up but my AM stations go to hell during the video feed. If I power up the camera but unplug the video the AM stations are clear. I tried grounding the antenna to chasis - no improvement Camera ground to antenna ground - no improvement Running out of ideas, might a filter for the video work? Thanks!

Try grounding the shield of the video RCA jack.

tried that too - no improvement

thanks for the response, 1. originally I wired the camera power to the reverse signal sensor on the pioneer (which will in turn connects to the reverse light - saving me one extra wire to pull to the back) - unfortunately the camera power seems to load down the input signal and the pioneer won't sense the 12v when applied. 2. decided to power the camera to the ign power instead (esp since the pioneer has an option to view the camera whenever the deck is on) - which results in AM static 3. will now pull the camera wire to the reverse light and live with the static.
