What to do if I see ERROR-19 on my Pioneer Car Stereo System?

If you encounter ERROR-19, it indicates a communication failure. Try turning the ignition switch off and then back on. Alternatively, disconnect and then reconnect the USB portable audio player or USB memory. As another option, switch to a different source and then return to the USB portable audio player or USB memory.
