Reverse camera interference

[BMGBMG]

Hi all, I'm wondering if anyone can help with an install problem on my car. I fitted a reverse cam to a 2002 Range Rover along with a android head unit. I spliced in to the loom at the rear and took a feed from the reverse lights and all worked well, that is until I switch the cars ( xenon ) headlights on and this makes the screen jump around.
Any ideas on what I could do to fix this ?
Thanks

might benefit from a relay... coil energised by reverse lights. contacts to power camera. i have a somewhat similar problem. evry time i turn on LED headlights, i get RF that swamps the radio on weak stations. (my reversing camera is powered from the rear screen demister (which is kaput anyway)so it's on when i want it, not just when i'm going backwards).
