I assume the answer is "no", but I'll throw it out here anyway.

Is it possible for the Z1 to pause the AV source instead of mute when a phone call comes in?

I'm using the Z1 with iPod adapter and Bluetooth adapter and it sure would be nice if the song on my iPod would automatically pause upon receiving a phone call.

If not automatically, does anyone with the steering wheel remote know if you can pause the track manually whilst on the phone?

Thanks...Mark

There is no pause button on the remote, but you can just turn off the source (holding the source button down), when you press it again, it will return to where it was.
