Any one install one of these? I want to find out where is the best place to mount it on the roof. I would like to do this with ut pulling the whole headliner out. Also, is it possible to hook the audio out the the factory bose 6 disc radio? Never installed a dvd player before so any tips would be greatly appreciated. Thanks in advance...

I had mine installed in front of the dome light assembly and ran the wires down the b pillar. Luckily there was a steel cross member there to mount the unit to. I did not have to drop the headliner down. I just fished the wires through with a big zip tie. I also used an fm modulator to play the audio through the stock radio.
