I've hesitated to post this because I feel I must be missing something obvious. But after asking a few friends, and spending some quality time with both my car and the manual, I've come up blank, so here goes. How do I keep the audio system from auto-playing when I return to the car? As far as I can tell there is no distinguished "off" setting for the audio system as there is on – dare I say – any normal car. If I stop the audio by pausing it, the pause doesn't stick when I return to the car after having been away from it. Of course I can reduce the volume to zero, but that's an ugly kludge. Surely there must be some way to do this. What am I missing?
