Audio input via
PAC AAI-GM24 allows 2 inputs and keeps all in the truck happy. I don't have the SWI-X interface (IR output from factory controls) so my rear radio buttons or steering wheel controls don't talk to my aux items now, but I could add that to control the computer via IR or any other items like if I decide to add a playstation or something. I have an IR serial interface for the computer, with volume, launch buttons, mouse emulation... just don't have it hooked up. I could mute the computer or launch applications without taking my hands off the wheel (and no aftermarket items are visible).
Rear seat or front passenger can watch (not legally) a dvd with the display in the center of the truck. They can all plug in headphones and watch the movie while I can use the stock CD changer or radio just like normal. (it shuts off rear speakers when headphones are plugged into factory rear control) I was also warned at one point that keeping the display low would help with glare, don't know how true that is.
Cops normally are pretty cool around here, but you never know. I normally don't have issues, but hate to give them another reason to hassle me. My front window tint is a bit dark, I don't want them to make me pull it off.
CPU pictures will have to follow. I only have 2.5" of height under rear seats (seats fold down for 8' truck bed which I use often) so the case had to be short. CPU will be shared with another car (shopping for newer honda accord now) but it can pop out quickly to drop into the honda trunk.
I think I will try and sell my drivers side sun visor:
My backup camera has been hooked up to that 5.8" screen for a couple years. I glued it in real well, so I can't pop screen out and put the mirror back in. Don't really need it now. Would have liked to move it over to the passenger visor, but too late now.
