The DVD ROM there is only for installation purposes. I've got a USB DVD that I'll be using. I just have to figure out where I am going to mount it.
So, the work I did earlier today was to add more hardware.
I popped on my old Sirius reciever from my old computer and I put on a bluetooth adapter on it. I also hooked up my old 12V->5V to the terminal strip above to feed my external USB hub, which I also hooked up. Next will come the Powermate, then I'll hook up my new HD radio. It'll be nice to have AM/FM in the computer. That's new for me.
I had said that things won't fit in the dash without modification. Here's a bad picture of what it looks like behind there. The Double Din is only about 6" deep, maybe. I am going to have to pull it all apart again tomorrow and take some good measurements.
