I'd like to have the ability to do something, but am starting to question whether it's even possible. I would like to have my phone set up via A2DP to my car stereo (currently an X710BT, but I tested with other models, include the Z series, and can't get it to work), and have it interrupt whatever the current audio source is if something comes in over the phone (eg, texts, emails, notifications). In other words, I'm listening to FM, and I receive a text or an email, I'd like the phone to be able to interrupt the FM, read the text/email (via an app on the phone, which I currently have), then
