    Just an update on what's been going on:
    I moved the PSU to the front of the car about 4ft. away from Mac Mini, and the flickering has decreased. The PSU was originally in the trunk about 10ft away from mini. I recently moved it even closer to the mini, now about 1 feet away; the flickering now is worse than it was before.

    I think that it maybe the connections on the power cables leaving the PSU to the mini. Perhaps my connections are bad that is why it has become worse now that it is much closer to the mini. Playing with the wires changes the frequency of the flickering.

    Those of you who are experiencing issues, are you using the macpack or did you make the connections from psu to mac mini on your own? Because, right now it seems that getting a macpack may solve my issue. I have also noticed that unplugging the USB decreases the flickering as well, but that is most likely due to using poor wires.

    any other news on this? i've had this same problem on my windows based carpc for years, but never really did much to solve it... now that i'm about to move to a mac based setup (specifically a ppc mini for now), i'm definitely more interested in getting this lil problem fixed.

    The ppc version never had the issue. The intel does. I've tried multiple different things, and it just seems that the intel mini is not getting regulated power so it causes image on the video out put to flicer. My macbook connected to the car screen has no issues. Household power to the macmini using the car screen also has no issues. So it's related to the way the mini is being powered in the car.

    Right, i have now got the Xenarc screen installed, and using the cables i have the power source is well shielded from everything else, athe vga cable i am using as an extention is excellent quality, and again shielded from all other electrical equipment....!

    The ONLY flickering i get is when the usb cable is plugged in for the touchscreen....

    Disconnecting cured the problem, and when i shielded the extention cable for the usb it went completely...!

    Maybe we should be asking Carnetix about it to see if they've had any reports?

    I am having the same problem. I was a 60hz and increased to 72hz and the problem went away entirely for a few weeks then came back. It drives me a bit nuts.

    I spoke with carnetix and he said the PSU has nothing to do with it. Which is true. It really has to do with the intel processors.

    I had some paper between the LCD screen and the wiring and electronics behind it. I took the paper out and the lines got a lot worse. When I get a chance I will try to use some different materials back there to see what helps the most.
