Same question. I have an S4 and there is no Prefer BT option. I have not be able to get the Waze App to play in the car via BT.

When you are listening to another source, you must select "prefer BT" in the Waze sound settings. This will allow it to "break into" the audio playing on the car stereo using the BT headset connection like your phone does for phone calls.

Can this be done in the Android version as well? Mine doesn't have a "prefer BT" option in the sound settings.

When I hit "prefer bt" every time it goes to tell me directions it connects as if my phone is calling someone! Any clue how to fix this?

,my BT works as a phone call but there is always a delay on my dedicated Bluetooth speaker or my headset if the source is not set to BT which causes me to miss some directions from Waze. Very annoying

I have virtually the same issue as Ed not having Waze break in like the phone or car's Nav program if I'm docked:

I have an iPhone 5S. I also have a 2007 Mercedes E350. I have a Viseeo Bluetooth device which pairs with my phone for calls only (it is instead of the MB brand Bluetooth device that does the exact same thing). For my dock I have an iPhone 5 style plug attached to a cradle with a 30 pin connector on the the other end. That plugs into a 30 pin cord that splits to a USB cord (for power and is attached to a cigarette lighter plug) and a standard headphone like jack that goes into my MP3 port in the glove box. That way, I can power my phone and get "line out" quality from my iPhone played through the stereo when it is set to Aux. It is also more convenient as the plug to the iPhone is at the bottom of my holder, so I only have to slip the iPhone into the cradle.

Regardless if I'm listening to my Sirius radio or the regular radio, if a call comes in the BT picks it up and plays through the speakers, albeit at telephone quality, not music quality. So, I know the iPhone and the BT are connected. (The car's built in Sat/Nav will also break into Aux, Radio or Sirius)

Likewise, if I do not have the iPhone in the dock and I'm using a navigation program, like Waze or Google Maps, it will interrupt the radio and give me the instructions over the same telephone connection. Again, that means the iPhone and the BT are connected for the Nav program as well.

If I have iPhone in the dock (cradle) and I have the Benz stereo set to Aux the Nav program plays through the stereo with much better quality than the normal BT/Telephone quality. That is all fine and good.

Here is my problem: when I put my iPhone into the dock the Nav programs will then only play the turn announcements if I have the Benz stereo set to Aux. For some reason they do not/cannot detect that even though I'm in plugged into the stereo (Aux), that is not the selected source and should therefore use the BT.

Are there settings I'm missing to have either of those Nav programs use the BT for the turn announcements even if docked, but the dock is not the currently selected source on my stereo?

I did make sure that "Prefer Bluetooth" is on in Waze and it doesn't make a difference.

Is there any Nav program that will work as I want?

Thanks,

Stuart
