I wish this was true, but I highly doubt they are going to upgrade MCU1 to MCU2 even if you bought FSD. They can't afford it. They will likely find a solution to get MCU1 to work but it will take time, or ask us to pay for the MCU upgrade.
I hear you and I’m cautiously optimistic. He made it clear that the screen would remain and that they were just swapping the mcu behind the screen. Not sure that would be so expensive. There weren’t that many cars built in the time period and far less who purchased FSD. If they don’t figure it out it’s going to cost them more. Meanwhile what great good will that would show and they would be standing behind what they said about these 2.0 cars. Let’s hope they get this figured out in short order.
