I was gunna post the same question tonite but saw this post on the front page! [Long time reader, short time member :-)]
I have an R34 with the popup TV and took it to a car stereo place to find out if it is possible to hook up a dvd player and australian tv tuner to the screen, but they recon it cant be done.
I cant see why not... when ya playin a cd the deck says "aux"...so surely it would be as simple as plugin the stuff in through the auxilary input...it is after all just a TV screen?!?!?!
As for the sat nav, dont think there is even the slightest chance of gettin that workin over here!
But the screen is still useful (for toss factor)...when ya play a cd the tv screen shows the tracks numbers and stop/play/fwd/rwd buttons...and ya use the sat nav joystick to move between em!
Maybe the HKS "CAMP" stuff could be hooked up to the screen at least...since both are japanese???

I only discovered the popup screen when I was on my way home from pickin up the car... "Damn where are my gauges on the top of the dash!!! hmmm...wonder what this 'open/close' button does....coooooooooooooooooool" :-)
