Only two downsides I am aware of with MCU2 upgrade are loss of FM and satellite radio and if using Light Harmonic aftermarket premium amp, it makes a popping sound on power-up and power-down with MCU2. My S has MCU2 and I have driven MCU1 cars - I would not be as satisfied using MCU1 on a daily basis, but suppose I could get used to it if I had to. I would still be worried about eventual failure of MCU1.
Is the MCU replacement just the chip or is it integrated with the MCU screen - such that the whole screen is replaced.
Also, & if so are the MCU@ screens less prone to yellowing ?
my 2018 came with MCU2, i chose it over an older car at the cost of $14,000 more, so i paid $14k for MCU2, still worth it to me
Even if true, it still would not mean that everyone thinks it's worth it. Worth is always relative "to whom". Personally I don't see $2,500 of value in the upgrade for my AP1 car (see this post if you're curious why).So many threads on this. No one has regretted the upgrade
I suspect you will find people who would gladly retrofit for you an MCU2 with an FM tuner for $11,500. Are offering to pay $11,500 for an FM tuner?But that $14K includes FM radio... whereas us $2500 upgrade people don't have that option.
Given the eMMC issues that are discussed in at least a dozen threads, I have concluded that it may be worth it just to get upgraded hardware that hopefully won’t have the eMMC issue, plus the four year warranty on those new parts. I previously was considering the expensive extended warranty but have concluded that since my battery, motor and new MCU2 will be covered another four years, I will skip the extended warranty and instead watch Netflix on my new screen while also enjoying the silky, smooth navigation screens. On the other hand $2500 ain’t cheap!Just want people's opinions whether MCU2 is worth the $2,500 upgrade.

You left out the free option. All of those assume that you NEED to replace your MCU1. Most of them are running fine, and it costs nothing to maintain what you have.
I shelled out around $2500 for a stereo upgrade and I think it was totally worth it. I am fine with my "slow" MCU1. I will consider an upgrade if it fails, but preempting it is not worth the money to me.
MCU2
- 4 year warranty
- you get fancy new features and lose AM/FM/XM radio
- much faster
- unknown reliability, likely better than MCU1 but worse than MCU1+swissbit
- Future proof(ish)
- $2500
...the EMMC should last somewhere between 100 and 200 years in otherwise ideal conditions....
