On my PC setup I got generator noise in the headunit when connecting the PC. I tried extra ground just about everywhere, but it didn't help. Then I started pulling cables from the computer. Turned out that when removing the 10.4 touchscreen LCD (not the touch controller, just the VGA cable) the noise dissappeared. I have two other LCD monitors in the car, they didn't create that problem. I tried running extra ground from the computer to the LCD monitor, but that didn't change anything. Removing the power adapter to the LCD did the same, but I didn't get anywhere changing power adapter or grounding that thing extra. Any viable suggestions (not "change monitor" or anything like that...) would be appreciated.
