Hey everyone. I am in the process of getting everything I want togther to do my car pc system. I know how to install the touch screen, I know how to hook the screen up to the PC and I know how to get power to the pc through a dc adaptor but I just do not know how I am going to hook the pc up up my headunit to play the music through my car speakers. Do I have to get a certain sound card or what. I am pretty knowledgable when it come to computers in general but when putting them in a car. BUMP THAT!!!!!!! Please help me out. Do i have to get a headunit with a specific input or what??? If anyone has a drawing or anything of how they have theres wired and what not that would help a great deal. If I choose not to do this, I might just get the screen and a indash dvd/cd/mp3/wma player and say forget it..... I really want to do the pc though.
