i have a jeep grand cherokee and was thinking the same thing
hrmm i observed it the other day and i was thinking if i could take the stereo out and move that somewhere. It is the infinity gold stereo, and it has the controls on my steering wheel. so location of the speaker wont matter.
now if i were to moved those 2 vents out,, a nice screen woudl fit right in there.
but damn, i dont know if i wanna move those vents..i wish i had a junk car to tear apart.
i gotta get some money and a good screen and a good spare puter before i try this task
