Well just thought that I would ask you guys what you think would be the best head unit to buy.
There are only a few limitations. It has to be be a double din, navigation deck with ipod integration, 24 bit DAC, High Volt Preouts. Basically the best SQ deck you can get with all the cool DVD Nav, IPOD and as many toys you can add option : )

Sorry I am leaning toward the Eclipse AVN-6620 unless anyone can recommend better

Eclipse sounds good. I'm going to try and work an Eclipse 7200 into my budget if I can. I've used pioneer, kenwood, and eclipse, and now that I've used and really like eclipse, I don't really want anything else (even though there are a lot of great decks out there). I am not into the dvd set ups though so I am not sure if there are any better options for you or not. Sounds like a great choice though.

I went and checked out that 505 today and it only has 2 volt preouts

So I went with the Eclipse AVN-6620

Can't complain about that choice

So after it was all said and done I ended up with a DNX-8120 by Kenwood.
All I can say is what a sweet deck.
I recommend it to anyone
