The basics... 2013 Prius Two This morning, the USB panel of the MFD/stereo was frozen. No response to buttons or touchscreen. All other stereo and modes worked fine. Turned off stereo and pulled USB drive. Waited a few seconds and reinserted it. Still frozen. Turned car off and repeated...still frozen. Tried it one last time, now the stereo did not come on nor could I turn it on. No Toyota logo. At this point, I accepted it wasn’t going to right itself and prepared to carry on. Suddenly, the Toyota logo appeared and the sound system was 100% back to normal. It was as if it rebooted itself, but I don’t see why that doesn’t happen at every power up of the car. Anyone seen this happen before?
