Hey, my first forum post. So far I'm enjoying using Waze, and it's even dissuaded me from buying a new Garmin Nuvi…but I digress.
My questions concern how sounds get routed from my iPhone 4 through my car's dock connector and AD2P Bluetooth headset (Plantronics M50). Right now, either everything gets sent to the dock connector, or everything gets sent to the BT headset.
What I would like to happen is to be able to send the Waze navigation prompts and phone calls to my BT headset and have my iPhone 4 audio sent through the dock connection into my car's stereo. Can this be done, and if so, how?
I listen to a lot of Audible.com books on my 45 mile one-way commute every day, so the above scenario would be great, however if it's not possible, is there a way to have the Waze prompts pause the Audible.com player during announcements, then have Audible start up after the announcement?
Going through Settings-Sound presents me with a Volume slider first - is this the volume for the Waze prompts, independent of the destination? The second selection, "Navigation guidance" is self-explanatory. The third and fourth are a bit cryptic: "Play sound to phone speaker" and "Prefer Bluetooth". Does this mean if I select "Play sound to phone speaker" to "On" that the sound will be sent to the phone's speaker only, or that the iPhone's speaker will be active in addition to the dock and/or headset? And what the heck does "Prefer Bluetooth" mean? Preferred by whom, or by what? What is the meaning of "On" and "Off" in this case? Does "Preferred - On" mean that, given multiple output streams, Bluetooth will be chosen if it's present? I'm confused.
