I just picked up a "universal dock" through apple, since it has a remote that can be used with it. I plan on installing in my car, and using the line out to connect to my line in on my stereo. I haven't tested this very much, but if I do this set up, when I receive a call, I assume the music will fade to mute, and then I will hear my ringtone through the car speakers, right? Just like if I'm listening to a pair of headphones, correct? What happens if I accept the call, now? Will it be on a speakerphone through my car stereo and iPhone microphone? Finally, what will happen if I pull the phone from the dock to accept a call, and then place it back? Will I have to open up the ipod again, or should it resume from the last place regardless? I know when I pull my headphones out, I have to go back into the ipod, I believe. And finally, how will this work with a bluetooth ear-piece? If I'm listening to music and receive a call, will I be able to accept it over bluetooth and then go back to listening to music on the phone?
