Alright, I am getting ready to start my third CarPC project and this is by far the most technical I have got with an install. I am using a CNX-P2140 with a Dell SX270. My first question is, what is the benefit of running my touch screen off the secondary +12v power on the 2140 instead of hooking it right into my acc. wire that used to go to my radio? I have a lot of other questions but I will bring them up as I go. Thanks a lot in advance.
