We have both MCU1/HW3 and MCU2/HW3 vehicles - and both vehicles are experiencing some software glitches with recent releases, causing crashes and blank displays.
Wouldn't necessarily blame MCU1 for those issues.
We've also noticed that a recent update has caused both MCU1 and MCU2 to take an extremely long time to restart (when pressing the steering wheel controls).
Not sure if this is still an issue - the navigation software used to have problems when the destination history list got long, slowing down the processor (even when not in the navigation app); clearing or reducing the size of the list restored performance. If this "feature" is still present, that could also explain difference between MCU1/MCU2 performance after the Infotainment Upgrade, since the upgrade likely loses the navigation destination history.
