Yeah, 06+ M (including Y51 '11+) the car shuts all electronics off after 20 min or whatever, even radio. Kinda pisses me off because I sometimes like to turn my iPod on in the car when I'm working on like the oil or brakes or something...problem is the car is 6ft in the air on my lift when the power gets cut lol.Larz wrote:If I'm not mistaken, the car has a feature that will shut off certain lights left on after a period of time in order to protect the battery. It still could be an issue. When I dismantled my trunk liner to add sound proofing, the trunk interior lamps shut off after about 20 minutes automatically.
