Well, too bad. I had the same response from Pioneer. I did the complete reset of the 8000NEX and also a factory reset on the Navi app part. Of course that cleared all my previous settings, sound measurements, 3D Calibration et. al. After a while, the 3D calibration/initialization completed again, but all of it DID NOT FIX the problem. Randomly, there is simply no response or a very delayed response to keyboard or button touches. But worse, now I have a new problem relating to the speedometer indication on the Navi screen. It lost its accuracy - remains stuck on the same value for several secon
