Alpine roof dvd interference

[C12jwalls]

Just installed a alpine roof dvd, but having a issue when the van is running I get loads of horizontal lines going across the screen, but when the van isn't running all is good and crystal clear.

Do I need some sort of relay to stable the current if so which one would I need links would be helpful

Many thanks

Chris

Does the power lead have a ferrite ring/bead attached to it? They can often help in cutting electrical interference. Most laptop cables have them so I would expect the Alpine to have one too, but you never know.

if your van petrol Engined the spark plug leads might need suppressors

If it hasn't you can just buy a ferrite ring and wind the power cable through it, cheap way to see if it works. One of the simplest interference fixes out there.
