Thread: Quick Question

I'm going to be building a car pc in a few months but i have a quick question?

I want my car pc to be like a factory installed type unit, Like all i really want is to have navigation and to play my audio files, that's it.

So what specs would i need to be able to do this nicely and it run smooth and things, and i want to be able to have sirius sat radio, so any help would do, im totally new to this.
