there's now a new "tuner2" connector on the new MCU. But The old connector is still there (no idea if it's connected to anything).

Audio components on new MCU and all related setting referenced to harman in firmware, I guess it's because sn1 was acquired by Harman Kardon, I'm not sure if actual hardware is different but quite possible
Couple of new connectors on MCU2. One new ethernet connection facing passenger side. One new radio tuner connector on the back side.
(The black one on the backside is for "Tuner2" as @verygreen points out. 'Das schtimmt' with the wiring diagram. Should be the new tuner that Model 3 has.)
No clue about that ethernet connector!

Just had my MCU replaced 2 days ago on my car. They were back ordered. Waited over a month. I wonder which version i got?
More then likely the old one, but simply look at your service invoice for the final answer.
I had my screen replaced earlier this week by a mobile tech. During our conversation I asked what happens when the memory chip in the MCU dies, and he said they replace the whole unit. He further said that they don't have the old MCU units anymore so they install the new unit with an adapter harness that mates to the existing harness in the car, as the new MCU is missing one connector that is found on the original MCU.
My car is a 2013. Thinking about it after he left, I'm not sure if he meant the new MCU is the new MCU2 or if he was possibly referring to a revised MCU1.

Go to this website The HTML5 test - How well does your browser support HTML5? on your Tesla browser. 500+ points if it is MCU2.

This sounds like the “AP2 MCU1” compared to the original MCU. It would be awesome if they started replacing with MCU2 but we would’ve heard something by now. MCU2 is so monstrously fast especially when it comes to maps that there’s no way one wouldn’t notice it.
MCU1 before 2018.14 only scored 120 points.
After 2018.14, MCU1 should reach 300 points.

If I was going to keep this mistaken purchase, I’d seriously consider upgrading to MCU2. For futureproofing, similar to the 3G to LTE upgrade for the last car, if nothing else. Although it may still be years before we get any cool features for which MCU2 is capable.
Yeah, MCU2 isn’t really ‘missing’ any connectors compared to the facelift MCU1. (Rather it adds to them, ref. pics above.)
Facelift MCU1, however, is quite different connector wise compared to the original (let’s call it ‘MCU0’). For example MCU0 has a big, fat, black one on the top row, that the MCU1 does not have.
A swap from MCU0 to MCU1 would therefore very likely need adapters. A swap from MCU1 to MCU2 doesn’t seem to require that
Current MCUs are not MCU2 at least for Tesla , MCU2 whatever it's have not been released yet, I would assume MCU 2 sites in model 3.
All references to current MCU in firmware call it mcu_transitional

The probably want to sandwich it all together like m3 MCU to decrease the intrusion vectors and cost cutting / ease of manufacturing

Should also consider that MCU2 uses the Vector maps and the new Google color skin, which MCU1 cars doesn't yet. The MCU1 will be a bit faster when the Vector maps are pushed out to older cars. Not MCU2-fast, but the delta will be way less.
I'm not sure if they going to push vector maps to MCU1 cars, maybe after some improvements. The performance of vector maps on MCU1 is super slow, I get 0 FPS sometimes and they constantly crashing
I’ll remain skeptical — the satellite view is not vectorized in either platform and the speed difference there is pretty astounding.
Routing is another huge difference — plotting a route from San Francisco to Phoenix takes a whopping minute on MCU1 and only about 5 seconds on the Model 3.
Oh, that's unfortunate
I assume that you have rooted your car so that you can test this?
Thought I've seen some yt-video from someone testing the vector maps on MCU1 and it did run very smooth. But I might have been dreaming then..
Thanks anyway for input!
