now that I have everything working with my in-dash monitor and dvd changer I am having a slight issue.

When I turn the car to the on position, the video gets interference. When I turn the key back down to the first turn (auxiliary position, I think), the video signal gets clear again.

Any thoughts? What could be giving me the video interference? I am pretty sure it is just from the video signal coming from the dvd changer, but I will check the other video inputs to see if the interference is happening with them also. I imagine this will help pinpoint where the interference is coming from.
