New vehicle part:  onboard media center!  (WIP, comments requested)

Because no post-apocalyptic deathmobile can ever have TOO many gadgets of questionable value, my latest project is the onboard media center.  The perfect thing for board passengers on long trips,  this little marvel has a gaming console, speaker system with pre-loaded music, and a multi-purpose radio system that can both listen to local stations and communicate with it's CB radio equipment.  It's high-gain antenna can even tell you which direction the signal is coming from.

This will probably be my most headache-inducing project yet, I have no idea if some of this is even doable.  In particular, one of my goals is for the music system in this to play via speaker instead of earbuds, so you get the morale boost if you're within a certain distance of the media center.  It would also be nice if some of these linked in to the vehicle controls the way headlights and horns do, as well.  It would be sweet to finally have cars with dashboard radios!

I could really use some advice if this idea is feasible and/or interesting, so please comment your opinion!
