Nice. In my 2007 FJ Cruiser, I bought an iPod controller that allowed me to use the stock head unit w/ an iPod and use the steering wheel controls. It was about $100

That was great until I got tired of listening to my iPod, even though it was full of 80 GB of music.

I then got a sturdy phone mount for my iPhone, similar to this.

Works great because it fits both my blackberry and iPhone. Similar to this, it mounts on the stock bolts in the car so no drilling and it's solid. Now I never even use the iPod functionality on my iPhone except for podcasts. I use Pandora and now Spotify (AWESOME) in the car.
