Just so you know... incase you don't... the D2 does not have a DVD drive. It has a separate drive for your nav disc so you don't have to take it in and out like you would with a N3, but to play DVDs you have to have another source.
BTW, be careful online. All these companies selling these Z1s for 1500 are pretty sketchy. I can tell you right now that 1500 is not even $100 over dealer cost.... and it retails at $2200. Plus if something goes wrong, you have to send it back to them and thats even if they warranty it. Pioneer probably does not offer a warranty of them they are just claiming that it does. Most companies will not honor any warranty unless the item is professionally installed and purchased from an authorized dealer, so beware. And you can find all this on every manufactures website.
