Yeah I have the same problem but it's more obvious for me..

I have a JVC GigaMP3 DVD Player and a single DIN 7" panel wired together on the same power and ground. The two are flawless, music and movies are perfect!

When I turn the CarPC on no extra noise comes into the audio or video, but when I switch the DVD player to line in (for the CarPC) I can hear the noise (the difference in power source) and then when I display to the 7" LCD from the CarPC I can see the noise..

So now I need a PS that can handle the JVC, the LCD, and my CarPC!? Plus a ground loop isolation circuit for the amps that are powered from a direct power connection?! Ack! Almost tempted to live with the noise when using the CarPC for nav/email/games.. Almost.
