Best after market head unit for iphone?
 

Looking for a head unit that works seamlessly with the iphone. I'd like one that I can play my mp3's and podcasts on, and also use as a phone over the car's speakers without having to do much. All while charging. And not something TOO high end. I want to use the iphone gps so I won't need a $1k unit that has that feature. And I'm not an import tuner, I'm not looking for anything too heavy duty to build a 'system' off of.

What are you guys using and recommending?

So far I'm looking at the Alpine CDE103BT. Looks like it does everything I need for a reasonable price.

I have the Dual xml8150 and I love it. It was simple to install and sounds great.
