Hi @ all,
Joining your forum for the first time, I’m having exactly the problems you are discussing. I am using a Samsung GT-S 7562, also called Galaxy S Duos. “Duos” stands for Dual SIM and I am using that kind of Samsung Phones since the days of SGH-D 880.
The Samsung runs on Android 4.0.4. My car is a Volkswagen Golf Variant, I think you call it Jetta Wagon in the States. It is equipped with a Radio, which is called RCD 310 here and with a Premium Bluetooth Kit (VW Phone).
This works together well when it comes to telephone audio and media audio via BT and it struggles a little with Phone Book Application Protocol (PBAP), but this is a known issue and I had it already with the previous phone.
I got to know Waze occasionally and I think I like it a lot. I first of all fully agree with what Venatius writes:
-
I do not have a “Prefer Bluetooth” button on the “Sound” page
-
I do have a checkbox “Route sound to speaker” on the “Sound” page
-
If I check the box “Route sound to speaker” and the Galaxy is not connected to VW Phone telephone audio and media audio in the car, the prompts are coming via the phone speaker.
-
If I check the box “Route sound to speaker” and the Galaxy is connected to VW Phone telephone audio and media audio in the car, no prompts are coming via phone speakers but if I have the Galaxy MP3 Player on, the music is interrupted wherever a prompt should be.
-
If I do NOT check the box “Route sound to speaker” and put the BT-Audio of the car on, I hear the prompts via the car VW Phone media audio, but if the MP3 player is on as well, I hear music and prompts simultaneously as the music is not paused. So I cannot understand the prompts.
Principally all this makes perfect sense and is not a bug so far. As Alan rightly says, Waze is probably meant to work like this. The user shall usually keep the box “Route sound to speaker” checked. And as some of you can see with iPhones the sound is now meant to go via the telephone audio and not via the media audio. At the same time MP3s are interrupted in order not to miss anything.
This way has the huge advantage that you can listen to the regular radio and get the prompts. You even can leave the radio off and the prompts will come through.
The disadvantage is it does not work with Android 4.0.4. The prompts don’t come via VW Phone telephone audio. I have tried it all but I have no idea what’s up. Maybe I have forgotten to get a setting right but I am afraid that the usage of BT telephone audio service under Android 4.0.4. is buggy indeed.
I would be grateful for recommendations to get this solved. I will post this report also as a ticket to support.

EDIT: Yesterday evening we tried the same with my wife’s Galaxy S III, running on Android 4.1.1. Exactly the same effects… Interesting by the way: The S III can connect via Remote Sim Access Protocoll (RSAP), which means that the car borrows the SIM from the cellphone and establishes the telephone connection on own hardware. At this moment the cellphone looses network connection and cannot do Internet anymore, which causes Waze to show “Searching Network Connection” and to be unable to calculate the optimum route. Is this the same with all smartphone navigations or Waze specific?
AND… I learned in the FAQ that Waze wants us NOT to check the “Route Sound To Speaker Option”. So my theory that they want to send the prompts via the telephone audio seems to be wrong. They want to send them via the media audio.
In that case you cannnot hear regular radio and you cannot leave the radio off. But then they really have a bug as they should at least stop the MP3 player when it is in use as long as the prompts are announced, like they do, when the box is checked.
Bottomline: The BT subject still needs some attention…
