I have my phone connected with Bluetooth and I'm using Android auto on it to control music. When I get a text message or hangouts message or Facebook I can press play and it plays the message back to me and I can respond by voice. The only problem is if I'm listening to Slacker it doesn't work I have to change the music source to phone wait a second play the message then switch back to Slacker which starts a new song. I guess it's safe to assume there's no way to have Bluetooth audio play over slacker or have slacker pause when Bluetooth is playing a message like in my other car right? Would be so handy since then I can use Google Assistant too in the car since the built in voice assistant doesn't do much.
