Well after alot of research I installed a dvd and monitor in the stock location, overhead bin. Everything went pretty well except I don't have the factory dvd harness in the console. I never did check the birth date but its an 04, bought in Dec. It doesn't have the Bose radio so I wonder if that's the reason the harness is not there or if they just quit putting it in the late 04's. Anyway, I just wired it to the aux. jack behind the dash. Works ok but I've got that volume problem. I'll have to put in a line amp I guess. The real problem I have is you can't seem to select AUX on the rear audio console for the headphones. As long as you have the rear speakers on, it shows AUX on the overhead but if you select headphones, it will only go AM, FM, or CD. I haven't checked the owners manual yet. Maybe you just can't do it that way, I dunno. Anyboy got any ideas why this might be happening? I'll try to post some pics later. I don't have a digital so it may be a while.
