Certainly! I drive a Fusion, so have figured out most of this, I think. There are issues with app/iOS which muddy the situation. Here's some info/tidbits, hopefully helpful stuffz:
1. iOS only allows the phone to output sound via one method at a time. Each output type (speaker, headphone, BT, dock) has its own volume setting iOS stores.
2. Make sure your phone and Sync and paired and that BT is enabled on both
3. Waze should have "Always output to speaker" and "Prefer bluetooth" options under Device/Prompts volume sliders. These two options are mutually exclusive. You cannot turn both on at the same time.
4. Waze's "device volume" doesn't update when another app changes the volume when Waze isn't running for the selected output method. Therefore, the speaker volume could be set very low or near zero and the device volume slider may not show that. The only way to adjust the audio up within Waze is to have Waze play a sound, such as activating voice commands, and while the sound is playing use the volume+ button to increase the volume.
5. When both "speaker" and "prefer BT" are off, Waze will use whatever output was last used, or whatever output is currently in use by another audio-outputting app like Music, Pandora, etc. In this mode, iOS will fade the other audio app output and allow Waze to overlay the other audio program. This will happen even if the other app is outputting to the speaker.
6. When "speaker" output is selected, iOS will force any app currently playing audio to stop playback and then play the Waze sound outputs. This will happen even if the other app is using the speaker.
7. When the iPhone is outputting audio/music to Sync, this is almost always via bluetooth streaming, but could be via the dock connector.
8. Dock connector, Waze, and iOS do not play well at all together. Long-term user Shorty-CM from BC, Canada, has been diligent in documenting issues with each beta release of the app.
9. "Prefer bluetooth" will send Waze sounds through the bluetooth "headset" mode (whatever that's called, I forget), which will make Sync see this as an incoming call, which will interrupt whatever audio is currently playing on the car stereo. This option also allows giving voice commands to Waze via a bluetooth headset or Sync.
