2011 factory prius This has been going on for a few years. At times the factory stereo display will go out (the background is lit but the led channel information is out), pressing one of the preset buttons may turn off the device, the on/off power button does not work. When this happens, if you wait a few days things will go back to working correctly for a while. It doesn't last. Is this head unit bad? Thanks for any feedback.
