First look at Tesla 2022.12 software update

By Nuno Cristovao

Tesla releases a major software update approximately once every four weeks. The latest public update is 2022.8. About 65% of owners are now in 2022.8, while others are still in 2022.4 or 2021.44.

However, we now have a first look at what will be in the next major release, version 2022.12.

This update is likely an early access or internal release, as it is not yet publicly available.

TechAU has shared images on Twitter that show some of the features available in 2022.12.

This vehicle appears to be in Australia due to the Disney+ prices listed and the fact that it is a right-hand drive vehicle.

Additional bottom bar customization

Tesla adds additional ways to customize the bottom bar, known as the launcher. Additional customization will likely come in the form of more apps or buttons.

We expect Tesla to include some buttons that were previously removed, such as windshield wipers, window defrosters and possibly seat heaters.

For more information, check out our coverage of the additional launcher customization.


Disney+ is going to be introduced in other markets. Since its introduction, it has been limited to the United States, but with 2022.12 it will be added to other markets.

Child lock

Child lock is a function that prevents the rear doors from being opened from inside the vehicle. This is useful with young children, but it can also bring its own setbacks.

It’s unclear what the child lock upgrade will be, but Tesla may let you choose which door should have the child lock, instead of locking both from the inside.

Additional mobile app controls

We know that Tesla is adding additional climate options to the app. Based on code found in 2022.8 and a previous version of the app, we believe the additional mobile app controls mentioned here are the inclusion of dog mode, camp mode, and weather guardian in the mobile app .

Support for new languages

2022.12 will also include additional language support. Tesla recently started adding support for two languages ​​in the past. These are not yet available, so we see Hindi or Turkish introduced in 2022.12.

There aren’t many details about this upcoming update yet, but it looks like it will include some of the improvements we were hoping for.

Keep in mind that there may be additional features in 2022.12 that are not shown here.

Features are often only available in certain regions or for certain models. The patch notes for a particular vehicle may not include all features of the update.

Update: Release notes for 2022.12.1 are now available. Be sure to check out all the features in this version.

MCU2 compared to MCU 3

Tesla hacker and Twitter user @greentheonly speculated that it will not be possible to retrofit Teslas current MCU 2 (Media Control Unit) using Intel chips with the new and improved Ryzen processor used in MCU 3.

Upon close inspection of the internals of a new Model Y, Green said “retrofitting Intel cars definitely seems impossible – totally different horsepower and other unit beams and thicknesses.”

The news has not been confirmed or denied by Tesla or its CEO, Elon Musk, but if true, it would most certainly disappoint many MCU2 vehicle owners, who expected to be offered the opportunity. an upgrade, in the same way current MCU1 owners can upgrade their chips for a fee of $2,000 (plus tax).

MCU (Media Control Unit) is the computer controlling Tesla’s touch screen, processors, RAM (short term memory), nonvolatile memory (long term memory), audio subsystem, 5 amplifiers, WiFi, Cellular, Bluetooth, GPS, Ethernet bridge, several CAN bus communications, LIN bus, USB ports and many more.

It handles all software operations except full self-driving/autopilot, which are unaffected by the version of MCU a Tesla is equipped with. All Teslas built after November 2016 are capable of fully autonomous driving.

MCU2 was released in Spring 2018 (Fall 2017 for Model 3) as an upgrade to the NVIDIA Tegra 3 processor present in MCU1. All cars delivered after this date benefited from the improved responsiveness and additional features that come with the Intel Atom E8000 Series processor.

From a technical point of view, the two chips had totally different architectures. The release of the V10 software update highlighted the differences, as MCU1 owners were locked out of both Tesla Theater and Tesla Arcade. This is because MCU1 does not support Netflix, Hulu, YouTube or any other streaming services that may be added in the future. It also does not support any of the games added by Tesla. Moreover, the web browser on MCU2 is much faster and more capable as it is built on Google’s Chromium platform.

In the summer of 2021, Tesla launched the redesigned Model S with a more powerful infotainment processor MCU. At the time, no one knew if this was Tesla’s next-gen MCU or if it would carry over to other models.

Then, at the end of 2021, the first news of a new generation of Tesla MCU chips began to flood the web, with reports from China that a new AMD Ryzen-based computer was present in newly shipped Model Ys.

The new MCU is faster and brings noticeable improvements in responsiveness in the web browser, as well as when using video streaming services, such as Netflix and YouTube.

Model 3 and Model Y can gain rear screen for entertainment

It looks like the new Model 3 and Model Y will soon get a secondary screen. In a recent tweet from @greentheonlynewer Model 3 and Model Y models with AMD processors have been discovered to have second-screen capabilities.

The connectors on the circuit board of the AMD-powered Model 3/Y indicate that it has a connector to power a “2nd display”. It is possible that the second screen is at the rear of the car like the new Model S and Model X.

The new Model 3 and Model Y vehicles have a circuit board similar to the Model S and Model X, but they’re not identical, so it’s not just Tesla sharing parts between the two cars and leaving the 2nd display port remains unused.

According to Green, a similar situation has occurred before, where the Model Y PCB had unused USB3 ports which were later populated in later revisions.

It’s possible that Tesla will add a rear display to the Model 3 and Model Y as it becomes a big selling point for Tesla.

The rear display gives you convenient features such as the ability to turn on the rear seat heating and adjust the cabin temperature. It also lets you manage in-vehicle music as well as some additional entertainment options like playing games and streaming movies from Netflix, Disney+ and more.

And while games and movies on the vehicle’s main screen can only be used while parked, on the rear screen your passengers are invited to watch movies on the way to their destination.

This is a neat feature and would actually cost Tesla little to add since the 8″ display is powered by the same hardware as the center display.

Alternatively, it is possible, but unlikely, that the second connector will be used for an instrument cluster display including speedometer, temperature, GPS and battery information behind the steering wheel.
