No audio when car is off over night.

really. i've owned several bmw's and i've never had one mute the radio on start-up. furthermore, my '07 x5 started manifesting this issue only recently & it occurs regardless of the time interval between start-ups & disappears as soon as i charge it. i'm not stating that this is an intentional programming feature or that it makes sense; i'm simply stating what i've experienced.

My problem is not the muting. I've made sure it's not on mute. There's just no audio until 5-10 minutes into the drive. It turns by ON automatically after that.

none of my previous bmw's ever automatically muted the radio on start-up & my current x5 never did either, until recently. i realize your problem is different than mine, that's why i started my reply with the statement that my issue might be unrelated to yours. my point was simply that our issues are similar (not exact), both vehicles are 2007's, & these vehicles have been known to exhibit odd programming quirks, especially when the battery begins to wane. only trying to help.
