Recommend a HU For Me! - 2011 Edition!

So, I've read a lot of threads about HU recommendations, but many of them seem to be a year or two old. With today's technology, I'm hoping for some more recent recommendations.
Here's my situation: Anticipating buying a 2010 II soon and naturally, would like to replace the HU for increased audio output, and other fun additions. I'm looking for a double DIN with the following features:

*great navigation features that also work in Canada and that hopefully will NOT need a paid upgrade frequently, if at all. Which navigation company is the best? Garmin, NavTeq, Tom Tom?
*great-sounding audio, where I hopefully won't have to replace the factory speakers.
*DVD player that can hopefully be modified during installation to play while car is in drive (for my passengers, of course).
*Bluetooth capabilities that will integrate with the steering wheel options.
*Minimal lag time when loading during start-up, when syncing with ipod, transitions, etc.
*USB port and AUX on the face of the HU.
*Voice command for ipod features, navigation, and phone would be fantastic!
*Back-up camera ready.
*Reasonable price/on sale now! **Hopefully around $600-700.

I KNOW that's a large wish list. Let me know what's out there! Thank you kindly!

 

Thanks for the reply. Indeed, it was your thread about the Kenwood DNX6960 that inspired my research! Thanks for that rockin' thread! A few questions on that model, just to clarify, if you don't mind:
1. do you find the included Garmin adequate w/o needing updates? It doesn't require any monthly service, correct?
2. are you able to modify the DVD player so it actually will play when the car's in motion? I spoke with a local installer today who said that wasn't possible w/Kenwoods.
3. the lag time is a concern for me. The initial loading of ~20 sec is fine, but do you find a lag when using the ipod interface or the phone?

Thanks!

 

Sold! Just ordered via 6ave.com--thanks to your coupon code (AFL4COUPON) it was $623w/free shipping. I think I'll be happy with my purchase. Now I just need to buy the Pruis!

A couple more questions:
1. With the 2010 Prius II, when I do the install kit, will there be a space below / small storage tray like what you've got or will it fit in completely?
2. Do you mind quickly listing everything else that I'll need for installation (kit, steering wheel column attachments, wires, etc!)?
3. Can anyone recommend an affordable, great back-up camera and installation accessories?
Thank you!!!
