I have this occationally. I'll leave the car and come back to find it pumping out music. I don't know how soon after I left that it woke up or what caused it but it is irritating and quite concerning.

If I had onw of my long playlists or the root playlist activated, I could come back to find the battery dead. Mind you this would take a while as I've found that I lose bass first, then the empeg starts slipping in and out of consciousness as the bass pulsates the battery voltage. But I am still able to start the car!

I would really like to know what sets it off.

I don't think, therefore I am not.
