When I did the initial research on the unit I assumed when I saw DVD on the description, I would be able to watch them on the screen. I've now come to find out it will only read the DVD nav disc. The only way to watch DVDs (I think) is to hook-up some external unit? No biggy I really don't plan on watching too much TV/DVDs while I'm driving or sitting in my car. That's what the big plasma @ home is for.
Pioneer's Z1 is their Mac Daddy nav, it has all the tricks, but it also runs @ 2Gz just for the unit. I only paid $750.00 for the unit, $250.00 for the rear camera and $50.00 for the iPod interface....CHEAP! Normally the unit itself runs $1500.00
I'm not too concerned about anyone breaking into my truck, I live/work in a good area, plus my car is always parked in the garage.
