While driving the low-mounted touchscreen went black. Pulling over and restarting the engine did not help. The high-mounted touchscreen froze.
While troubleshooting I remembered I inserted an USB stick to upload the music content, removing the USB stick and restarting the engine again solved the problem.
Clearly the software/firmware stumbled over the upload action (while driving).
