I dont know shit about car audio.... nothing at all. I want a new head unit for my viggen that can play MP3s but every time i get the balls to go to the store they are like uhhhh saabs.... your radio is hooked up to your computer.... you cant do it or we dont have the kits or somthing always happens. so whats the deal? can i put one in myself? where do i get an install kit? etc.
