This version also behaves very poorly in relation to music playback and car stereo connections. If I forget to exit Waze and disconnect from the car stereo before starting the vehicle back up it makes the whole device act strangely. Music playback doesn't begin. Forcing it to pause/play doesn't help. The device acts like something is caught in a horrible loop and gets incredibly unresponsive, requiring me to shut down and reboot the device, *if* I can even get it to respond well enough to get it to shut down.
It's incredibly frustrating when I start the work truck back up and notice that I forgot to exit Waze, and the "Kaaaaaaaahn!" -style NOOOOOOOO! begins echoing around inside the truck, haha.
I don't know how the connection/communication differs when starting the vehicle versus simply plugging the device into the stereo that's already up and running, but I don't think I've seen this unresponsive loop behaviour in that scenario. But I think 9/10 times when I do this if Waze is running the music won't start playing. The stereo goes through the normal 'reading' phase and then brings up the current track's name but is blinking as though playback is paused, which it shouldn't be. When this happens, sometimes simply exiting Waze will automatically start playback again. Sometimes it does not, and I have to disconnect the device from the stereo and plug it back in again. 1/10 times pressing pause/play will start playback again in that scenario, but it's usually faster just to unplug and replug rather than try hitting pause/play over and over and hope it works.
As a result, my usual routine when getting out of the truck is to grab my phone and exit Waze so that when we're getting back in and taking off again it is already out of Waze and obviously disconnected from the stereo. If I connect to the stereo first, and wait for music playback to start, and *then* fire up Waze everything will be just fine for the duration. But if Waze is running before connecting, whether or not the vehicle was already running, it is just going to be a disaster of some sort.
A version or two ago seemed to have all the volume and music playback problems sorted out, so I don't know what has changed, but it is once again broken, and is worse than ever in some respects. At least the volume problems haven't returned, so that part still works properly.
