Here's a pic of mine. I can control the music on my iPhone with the Sony stereo deck. When a call comes in the song does a really quick fade out (1/2 second) on the music and you just slide to answer and hit speaker. Everything else is hands free. As soon as the other person hangs up (or you), your music does a really quick fade in to resume. Since it's connected with a USB cord (rather than an axillary input or FM transmitter) it has the best sound quality, charges the iPhone, and can be controlled from the deck.
