My Pioneer radio just stopped working the other day. When I turn my car on the radio will start up like normal but once it reaches the screen that reads "Pioneer" and says loading underneath, it will freeze for a few minutes before flashing white and going back to the "Pioneer NEX" screen. After this it will flash a few more times before the screen completely shuts off. Right before this started I was unable to use the touch screen or volume buttons. Hoping someone knows how to fix this so that I don't need to buy a whole new radio
