I agree that the MCU upgrade is starting to become valuable, as the list of things you gain is much bigger than just a few games.
Tesla MCU 1 what it's missing/what you will gain
- Some games (Not that important)
- Netflix/YouTube (Can live without it)
- Caraoke (Really nice but not a deal breaker)
- Back camera for sentry (now it starts to get serious)
- Snappier menu's & zooming of Maps (important every day, every time you interact)
- Faster route calculation (Definitely a plus)
- Release notes will always work instead of staying mostly blank (Kind of nice)
- Internet/web browsing will become usable again (it's in there and should work right?)
- Will connect to my 5Ghz WiFi (performance will likely be better)
- Improved Bluetooth
- Latest emcc chip (kind of important if you're out of warranty, might turn out to become the biggest bonus of upgrading)
- Will receive future software features that are deemed impossible for MCU1, no longer left out (This is a big plus)
