Tesla infotainment system upgradeable from MCU1 to MCU2

Its not that the current MCU 1 Ultra Premium Sound isn't good. I've heard the sound in MCU2 Ultra Premium sound cars and it sounded better. Rationale I've heard (perhaps incorrect) is that MCU2 offers the immersive option (better codecs?) that MCU1 isn't able to support.

Good to know. I'm guessing that the issue for the error message you quoted could be due to fogging up of the internal front camera. You are in a really cold place and being winter.... I have had the same temporary problem and error message on rare occasions and that was the reason.
No it doesn't. If you want your parts back, you need to inform them before the repair is performed and they can notify you then if there's any additional cost associated with them not keeping the parts. A core charge is a fee charged when when you buy a part, that's refunded if you return the old part.
Probably a bit too soon in their lifespan for many MCU2 failures, but I believe wk057 has written here that he suspects the MCU2 may eventually suffer a similar fate as MCU1. When he speaks, I listen. But I do intend to buy the MCU2 anyway, so I sometimes listen and then let the good info sneak out my other ear. However, my uncertainty is causing me to consider buying the expensive extended warranty when I have to decide in ten months! (Not sure whether the MCU2 might have a warranty extending longer than those ten months.)

Or even different speakers and amps by this point. It has been years since MCU1 Ultra Premium.
standard parts warranty on new MCU is 4 years:

don't forget that you also need to somehow route radio (and xm) antennas there.
The 50 year old FM radio.So now that the infotainment upgrade is confirmed, what are we going to b**ch about for another 140 pages?

The display and MCU are 2 different parts.
I dont think you will get both replaced.
When i upgraded to MCU2.5, they did not change the display.

Having experienced both the MCU1 and MCU2 premium sound, the MCU2 is much better. I also think it's due to the levels of immersion vs. the Dolby surround of the MCU1. Speakers and amps may be different as well but that is pure speculation.
The MCU is the big screen in the center of the dash. That's what this thread is about. There is no MCU 2.5 - only 1 and 2.
I think you're confusing it with the self drive computer, which is either HW1, HW2, HW2.5 or the new self drive computer HW3. Your car based on the year you list in your sig would already have MCU (Display screen) 2 and if you have every option minus rear seats then you would have started with HW2.5 with an upgrade to HW3.
and someone would pay for it, then pay the labor to pull the old one out and put the new one in. Then forgo their warranty.
Sounds like around $2500 for it, and the labor alone.
or pay telsa for MCU2 and keep their warrenty.
I understand what he's saying kinda (minus 2.5). The actual screen and MCU are 2 different parts, which brings up a good point. Will Tesla be separating the screen from the MCU and putting your old screen on a new MCU, or will the MCU/screen be replaced as a whole... and my question still stands (i believe)... will we get our old MCU1 back after the upgrade or will Tesla try to steal it?
The MCU1 processor should be capable of displaying the FSD preview visuals - and likely could support many of the features that are now running only on MCU1.
The reason why we don't see those features on MCU1 is likely more to do with software resources than any MCU1 hardware limitations. With MCU1 an increasingly smaller portion of Tesla's vehicle fleet, it's becoming harder to justify expending any resources on adding new features to MCU1.
For now, FSD on MCU1 loses the improved visualizations - and it's very likely that list of missing features will grow longer over time.
When we get the infotainment upgrade e-mail, will schedule the appointment and request the MCU2 radio to be installed - and if the Service Center can't do that, we'll cancel the infotainment upgrade, at least until they can find a way to provide the stations we listen to on our radio today.

MCU 2 also runs on a eMMC, all emmc will fail once it's life has been used up. The eMMC is a lot bigger, however it will be interesting if they cache video for smooth playback. Repeated writing of high res video is a great way to use up a large chip.
MCU2 requires a new IC the old one will not work. I suspect the old ones are kept as part of the upgrade as they will use those to refurbish for future replacements. You should ask if you can keep yours before work begins.

Actually the MCU1 wouldn't be displaying the FSD preview visuals. That would be handled by the IC1 computer, which may not be up to the task. With the MCU2, at least in new vehicles, the IC is just a second display on the MCU2 instead of being a separate computer.
