E39 Radio turns off every 20 minutes
There is this luxury feature with the BMWs where the radio will play for 20 minutes without the key in the ignition. That's all fine and good. But, my radio has the same timer when the car is on. Every 20 minutes, the radio turns off, as if the car was not turned on. I have no idea how to fix this.
Car is a 2001 530i with business cd radio package.
