I updated a few days ago and experiencing the dreaded "Touchscreen Unresponsive" error on the MCU. It happens usually during the day or first thing in the morning. I turned off Energy Savings (kept always connected ON) and seems to fix the issue, however, my vampire drain is significantly increased.
the trick is to start the car first THEN reboot MCU by pressing both scroll wheels. otherwise, you'll be holding both buttons down for a long long time. nothing you can do now but to wait until the next update to fix this bug.
