Feel like I've been living with this through a few software updates + resets of the entertainments system. The pattern isn't 100% but definitely happens more than you 75% of the time. After arriving at a location and exiting the car and running into somewhere for a few minutes, when I come back to the car and get ready to take off, the audio will automatically mute itself (the volume indicate on the screen shows the little "x"), and then a few seconds later it comes back to whatever the setting was. Doesn't matter if it's on the radio or streaming, and isn't related to going on/off a location w/ wifi as it happens when i go to the grocery store. Not a huge deal but it is annoying if you're listening to a news story on the radio and miss a 15 second chunk when it's something interesting. Have waited a few software updates to see if it'd resolve itself and I've done a bug report right after it happens but wanted to see if anyone had the same issue or if it was something people brought their car in for.
