I do not believe that any app can output over multiple connections simultaneously, it can only be one. I wasn't trying to give the impression one could choose multiple simultaneous outputs.
Not sure if we'd wandered off topic, but I wasn't trying to output to multiple connections from one app - I was hoping to have several apps outputting to separate connections: Waze to the BT headset; Audible.com to the dock connector; iPhone output to the BT headset...

Alan, thanks for the clarification, but in providing it, you've confused me. The way I've read it in other threads, this is how things work:
Prefer Bluetooth on: Music fades out. Music pauses. Instruction plays through audio connection. Music resumes. Music fades in.

Prefer Bluetooth off: Music fades out but continues to play. Instruction plays over music through audio connection. Music fades in.

These scenarios assume that music is playing through a USB audio connection and that a Bluetooth handsfree device is connected.
is this not correct?

Why not rename these options?
Or remove them if they don't seem to do anything (prefer bluetooth)?
Or add some text to explain the options?

"Play sound to phone speaker" sounds to me like that if this is turned of Waze sound not send any sound to phone speaker. Bur clearly that's not what it does.

What I find very strange is that Waze overrides the silent switch (on iPhone at least).
In my opinion this is very much unwanted behavior.
Silent should be silent.
Some things that may be relevant:

* In general with Navigation application the silent switch is not going to impact voice directions. You need to disable or mute the directions in the navigation application.
* Play sound to speaker seems to work if you have another option 'connected' for audio. For example if you have the iPhone in a TomTom dock with it's own speaker - if you configure Waze to use play sound to speaker it will continue to use the iPhone speaker vs. directing the sound to the TomTom speaker. I believe it works the same if you have headphones plugged into the iPhone. Waze will continue to send sound to the iPhone speaker vs. to the headphones.
* I believe Bluetooth is only relevant if the Bluetooth device has is a stereo Bluetooth A2DP compliant device. I have not tested this so I may be incorrect.

Here is some information from a competitor, MotionX-GPS Drive regarding the iPhone silent switch:

"When I enable my iPhone's ring/silent switch, should voice prompts and iPod music be muted?

As is standard for most navigation programs, voice and music will play regardless of the ring/silent switch setting. Button presses and any other sound effects will be muted, however."

I thought I would give my ten cents worth as well. Yesterday I managed to get the Waze navigation and voice calls to work through my bluetooth headset and music through my car's speakers. What I did was to connect the iPhone to my bluetooth and tested that Waze and voice calls works. Then I connected my dock and tested that music plays through car speakers. It worked and I was very happy because that is just what I wanted. It worked perfectly for about 80 miles and then all of a sudden switched all Waze notifications and Voice calls to the car speakers. When I got to my destination I disconnected my phone from the doc and turned off the bluetooth and tried to set it up again as I explained above but could't get it to work. Everything went through car speakers. When I got home I tried it again without ant luck.

Does anyone know if the iOS API gives an app that level of control across different outputs all at the same time?

I didn't phrase my original question very well. This is exactly what I was trying to get at.
