Clarion NX500: Any experience with it?

I can't stand the wimpy stock stereo any more in my 2010 Access cab. I ride around with it displaying MAX VOLUME and can barely hear over wind noise with the windows down. Looking to upgrade the head unit first, then speakers and add a subwoofer.

So far in my search, the Clarion seems to be the best bang for the buck. I want:
in dash navigation
Ipod controls that work with the Iphone 3G
integration with steering wheel control
bluetooth.

My budget is about $700 for the head unit with any adapters and other add ons, so far this seemed the best unit I can find within my budget and with what I want it to do.

Does anyone have any 1st hand experience with this unit?

 

I sell that unit. I have installed it in 5 or 6 customers cars and have never got one back. I personally prefer pioneer or eclipse but there isn't anything wrong with the clarion stuff.
