To all those thinking of upgrading, I recently swapped out my MCU1 emmc chip with a new one. MCU1 is performing better than new. No, I don't get any MCU2 specific features, like netflix or some games, but for me personally I couldn't care less (have MCU2 in my wife's car, never used any of the MCU2 features). The emmc chip I put is massively over-speced, but because of this, I can pretty much guarantee that it will provide this same level of fast performance for the next decade or two (it's expected life is 140+ years). As a reference, the original chip I pulled was reading at an average 17MB/s, the new chip reads at >100MB/s (sustain read speeds, burst is faster). I have zero desire to pay to get MCU2. Heck, I much preferred to have the separate IC still functional when the MCU1 was dead - you can at least charge/drive the car. At this point, I would not even pay $500 for MCU2 (I have AP1, if I had AP2.5 I might be tempted to pay $500).
