Funny, but I for one think that this place could do with more silly and fun questions to beat the boredom and / or break the ice for new users. It'll probably get more engagement than 5 or so hyper specific questions a day at least. But to answer your question, I didn't see the need for both a TV and an air hockey table.
I do not. Pimp My Ride did not pick my 2006 Carolla and I never got to meet X to the Z Xzibit. Really set the tone for the rest of my life unfortunately.
...i disassembled the factory radio in my 1990 geo prizm and soldered an auxilliary cable onto the pre-amplification stage traces; it worked pretty well suspending a portable CD player from the rearview mirror for shock protection back in the days before memory buffers were a thing, even better with those little vinyl bands installed around the disc edge for additional gyroscopic stability...
I have an aftermarket double din headunit running windows ce. I beleive it does have a tv tuner as well as dvd/gps/usb/micro sd card. I didn't hook up the brake switch so you could watch movies while driving if you wanted. I only use it for bluetooth and backup camera.
In the mid 2000s I had a little TV with a PlayStation 2 console, but going over bumps scratched the games so I took it all out. It was fun for a while.
