Tesla infotainment system upgradeable from MCU1 to MCU2

My car was ready last night but I couldn't get my keys back until this morning. I got them early.

All of my Voice command issues are GONE. night and day difference. I would go as far to say that my MCU had to have been defective. Now could I get any money out of Tesla, I doubt it. Voice command was right on the first time. The Nav loaded it right up and ff we went,no more delay. This alone made the upgrade worth it. the response on everything is so much faster.

I will say driving during sunrise I am getting a lot glade on the new IC. That has been my only negative comment.

Music appears to be the same, but i want to drive some more time to test.

Got traffic lights and cones. Back up camera is instant also.

I want to post Zanary's post again since it is so many pages back and it is good list of changes.

DONE!

My Infotainment upgrade has been completed. Dropped off my Model S on Friday, and picked up a few hours ago. Here's my details writeup.

-----

Summary: This is possibly the best $2500 you will even spend on your Model S/X.


My Vehicle: 2017 Model S P100D, built and delivered in September 2017. It is equipped with MCU1, AP 2.5 and I have the Full Self Driving pre-purchased. It’s fully wrapped with a graphic wrap and had no issues with Tesla performing the upgrade. I was already running 2020.12 prior to the upgrade. Still running 2020.12 after the upgrade. I only noticed that they pushed out 2020.12 just once after it was all completed. I assume that the option codes were updated, so when 2020.12 was re-installed it added all of the new “stuff” that is supported on MCU2.

Here are the details that might interest some of you.
  • You do get a new MCU screen. Mine still had the plastic protective wrap on it which I remove when I got into the vehicle.
  • You do get a new IC screen.
  • All settings are retained except for. (1) WIFI settings/connections, (2) Bluetooth settings/pairings, (3) Web browser favorites.
  • Trip values, and custom labels are retained.
  • Seat positions, mirror positions, and driver profile settings for each driver remain.
  • Navigation history and favorites are retained.
  • Favorite audio stations are retained (Slacker, and Tune-In)
  • Historical audio stations are also retained.
  • The warning “beeps” that Joe Mode reduces are much louder than with MCU1. This may freak you out at first, but it's loud. It will sure get your attention.
  • Two type of vehicle calibrations are needed. (1) One for Autopilot basic features, (2) One for lane changes with/without notification. If you go into the Autopilot Settings you’ll that the second one only starts to calibrate once the first one has been completed.
  • Wifi appears much quicker
  • LTE appears much quicker. It still connects to 3G when out of 4G and LTE range. The bar visuals have no change, but connection is much quicker.
  • The games had to be downloaded for the 1st time. You need Wifi for this.
  • There was a required Navigation update that had to be done over WIFI.
  • Overall, the MCU is 100x quicker. HUGE improvement in responsiveness. HUGE improvement in refresh of data on the screen.
  • Visuals on IC2 are 100x smoother and more detailed than before. Animation is 100x better as well, and so smooth.
  • All visuals (garbage cans, cones, lights, road markings, bike land markings, etc…) all appear on IC2
  • I did have to re-enable Ambient Lights. Maybe they turned it off during the install.
  • The scroll wheels are hugely responsive. Each scroll now is recorded whereas before I would have to scroll a few times for it to reduce the volume or the temperature (both scroll wheels behave the same, so it was not a defective scroll wheels). Now, they operate so smoothly and with immediate response.
  • I have the Premium Audio (which was standard on my MS). Before the upgrade I had a EQ that went to 12. Now it only goes to 8. It also has Immersive Sound with three options, however I tested it out with a variety of music (classical, dance, gansta rap, disco, pop, and Spanish), and they all sound the same. I think before I had Off and Dolby Surround. Now I don’t see Dolby listed anywhere.
  • The release notes, manual all appears immediately. No issues with a blank screen anymore.
  • YouTube works perfectly (like your iPhone in portrait mode where the vide is on the top, followed by meta-data below it). Sound quality is impressive for YouTube.
  • I got my USB Drive working again. Just plugged it in. Before I dropped it off, I got the “USB Full” false positive error that everyone is reporting (even on 2020.12), but when I just plugged it in after the upgrade, it works perfectly. Not too sure why as I had 2020.12 before and after the upgrade. Very happy that it’s recording both Sentry and Dashcam again. It’s the S500 - TeslaCam SSD Extreme from PureTesla if anyone is curious.
  • There is no FM/AM/XM radio. We knew that, but I just wanted to confirm this finding in the event you were hopeful.
  • I did not get to keep the old MCU1/IC1. There was a $1000 core charge if I wanted to keep it.
  • I did not notice any sort of USB charging speed increase (in case you were thinking that the amperage might be increased).
  • Before you drop off your vehicle, turn off any Vehicle PIN you might have setup. You will need to re-enable it once you get your Tesla back.
  • When you re-pair your Tesla with your iPhone, the name will now change to Tesla Model S followed by the name of your vehicle. Before the default was just Tesla Model S.
  • When I re-connected my Tesla to my home WIFI, it shows up with a new MAC address, and the manufacture of the chipset appears to be LG Innotek now (previously it was Parrot SA). I’ve only noticed a 2.4ghz connection, but I’m sure it will switch to 5.0ghz when it needs to download something heavy (software, game updates, another navigation update).
Note: I mention x100 throughout the above bullets not as a exact measurement, but as a emotion statement to indicate that it's so damn quick. It's night and day!
 
Radio doesn't appear, and the 10 radio stations I added as favorites just before I dropped off my Tesla for the upgrade are all gone. Looks like they covered all edge cases as part of this Infotainment upgrade.

But, Slacker/Tune-In works so much better. I know it won't give you your FM or AM stations, but the experience of everything working on MCU2 is just unbelievable... It's hard to explain, but it feels like Christmas in March!
I just realized a lot of the FM stations are available streaming. If you don't have a signal, you'd better have music on your mobile (I don't) or just be okay listening to the drive (I do.)

I have a car with 4G that I paid $1600 for the instrument cluster recently, maybe when the MCU dies again I can save the cluster for the other Model S, unless that MCU dies first.

The new MCU won't crash because the flash memory is full, is that correct?

Flash memory of any type has a finite lifespan. The difference is with the MCU2, there is more flash storage (I recall reading 64gb vs. 4gb but I am not certain) and the writes/rewrites are randomized more so the same section of the flash memory is not being overwritten time and time again. The thinking is that the memory should easily outlast the life of the car.

So can it? Sure. Will it? Most likely not.

64G vs 8G

that said two weeks ago I got my first mcu2 board with dead emmc in the mail. It was dead in a very strange way. Just turned readonly (According to the logs - shortly after a firmware update). Worst part - getting a replacement appears to be hard. I have not yet found any place that would sell you less than a lot of about 1000 (at ~$85 per piece). The good news is it's definitely still under warranty.
 
I didn't catch my typo on my post above. I should be I was catching a lot of Glare on my IC driving away from the sun.

I didn't loose my home link connections. Only had to reset Wi-Fi and Bluetooth connections. I haven't caught any other setting changes.

Radio change from Dolby to the Immersion sound, I can't hear any difference yet, so probably not an issue as feared.

IT was trash day in the neighborhood and i think the display showed everyone of them. Funny how it picks up the trash cans but ignores the parked cars, you would think they would be just as important. Getting all the stop signs, traffic lights, stop bars, turn lane arrows, and traffic cones.

Defiantly worth the upgrade. The processes are that much faster as noted above.

I had my upgrade yesterday. On the drive home the cellular data would connect and disconnect over and over again. Any idea what procedure was missed that would cause this behavior?

Yes I did reset the computer several times.

Maybe I should do a factory reset.

It may be that one of the antenna wires was not fully seated to your cellular card, loose wire would cause connection to drop off and then try reconnecting again as the wire end cap touched the card connection point.

That is what I thought as I was driving too. Of course I only drove a few miles and returned to the SC expecting them to reseat a connector, but that didn't happen.
 
Still a hard -NO- on the right coast.

Factory reset is just personal data, doubt it would do anything to help this, does sound like a mechanical issue unfortunately.

Where on earth do you keep getting MCU2s?
