Is there anyone using an iPhone with USA Spec's iPod adapter for the stock stereo?

I'll be doing this as soon as there is a 3G iPhone and I and wondering if there's any phone functionality that can use the car stereo.

What happens when you have the iPhone plugged in and are listening to music and you get a call? Does the ringtone come through the car stereo? Does the actual caller's voice? Any difference in speakerphone mode?

Thanks, and... is it awesome???

 

it says its not compatible but i have the musiclink in my car and when i use my gfs iphone it works okay, and when she gets a call the ringtone goes through the speakers, its kinda weird but itll work

 

On Crutchfield it says it works with iPhone and iPod Touch.

Good to hear that the ringtone comes through the speakers. I presume the actual call will not come through the speakers?

Have you tried putting the iPhone on speakerphone mode while plugged in?
Maybe (I wish) it would switch to put the sound through the dock connector... yeah, not likely.

Anyway.. anyone else use this setup???
