I have an iPhone 4S, running 5.1.1 jailbroken. I recently bought a car stereo with a USB input which will also control the music app. Every time I use the stereo to skip tracks, the iPhone screen lights up for a few seconds. It is driving me crazy, especially at night. The stereo shows the track name so I have absolutely no need for the phone to light up every time. Does anyone know of a way to disable this?? I do jailbreak so if there's something in cydia that would help I am open to that.
