Every laptop I’ve used in a car gets engine noise thru the car power adapter it’s really annoying. a car PC with roadrunner installed and a good 7in touch screen is awesome, but it’s a big mod and there’s a lot of setup involved. You can buy a car pc power supply that puts the pc into hibernation when the cars shuts off and it brings it back up fast when it’s turned on. I’ve maid a custom roadrunner interface for my laptop I’ve been toying with the idea of installing a car PC.
