MCU2 compared to MCU 3

Tesla’s MCU 2 likely won’t be upgradable to MCU 3

Tesla hacker and Twitter user Tweet embed It was speculated that it would not be possible to modify the current Teslas 2 (media control unit) MCU that uses Intel chips with the new and improved Ryzen-based processor used in the MCU 3.

On a closer examination of the new interior of the Model Y, Green stated that “retrofitting Intel’s cars certainly seems impossible — completely different power, harness and other thickness of the unit.”

The news has not been confirmed or denied by Tesla or its CEO, Elon Musk, but if it proves to be accurate, it is sure to disappoint a large number of MCU2 owners, who had expected to be offered the possibility of an upgrade, in the same way that MCU2 owners could. Existing MCU1s can upgrade their chips for a fee of $2,000 (plus taxes).

MCU (media control unit) is a computer that controls the Tesla touch screen, processors, RAM (short-term memory), non-volatile memory (long-term memory), audio subsystem, 5 speakers, WiFi, Cellular, Bluetooth, GPS, Ethernet bridge, multiple CAN bus connections, LIN bus, USB ports and many more.

It handles every software operation, except for fully autonomous driving/autopilot, which is not affected by the MCU version that the Tesla is equipped with. All Tesla cars built after November 2016 are fully self-driving.

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

From a technical point of view, the two tranches have completely different structures. The V10 software update release highlighted the differences, as MCU1 owners were excluded from both the Tesla Theater and the Tesla Arcade. Effectively, 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. In addition, the web browser on the MCU2 is much faster and more capable because it is built on the Google Chrome platform.

In the summer of 2021, Tesla released a redesigned Model S with the most powerful infotainment processor MCU. At the time, no one was sure if this was the next generation Tesla MCU or if it would carry over to other models.

Then in late 2021, the first news of a new generation of Tesla MCU chips began flooding the web, with reports coming in from China of a new AMD Ryzen-based PC in the newly delivered Model Y.

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

Model 3 and Model Y may get a rear screen for entertainment

It looks like the new Model 3 and Model Y will get a secondary screen soon. In a recent tweet from Tweet embedit was discovered that the new Models 3 and Y with AMD processors have the capabilities of a second display.

The connectors on the circuit board of the AMD Model 3/Y Trigger show that it has a connector to power a “second display”. Like the new Model S and Model X, the second screen could be at the back of the car.

The new Model 3 and Model Y vehicles have a circuit board that’s similar to those on the Model S and Model X, but it’s not the same, so not only are Tesla parts shared between the two cars and let the second viewport not be used.

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

Tesla will likely add a rear display for the Model 3 and Model Y as it becomes a big selling point for Tesla.

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

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

This is a compelling feature and it will actually cost Tesla little to add because the 8-inch screen works the same hardware as the center display.

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

Soon you will be able to connect to more Wi-Fi networks

Tesla is said to have begun testing a new feature for its fleet: the ability to connect to Wi-Fi networks provided by its Internet service provider.

Connectivity is an integral part of the Tesla experience, enabling vehicles to receive periodic software and navigation updates, access to entertainment options, as well as allowing the company to receive valuable datasets from the fleet, which is used to improve features such as autopilot.

Although Tesla initially offered free internet access, as the fleet evolved, the company began ordering a new paid Premium Connectivity package for the monthly subscription in order to access some of the more data-intensive services, such as music and video streaming. Tesla owners have had to choose if they want to pay $10 a month for premium connectivity since then.

Regardless of whether you pay for the premium connection, almost all of the features are available for free on Wi-Fi.

The automaker also continued to research alternative solutions for its customers, including a recent software update that allows owners to use their phones as hotspots while driving as an alternative to a calling package.

Tesla is said to be working on a new option that includes the use of Wi-Fi networks for internet providers. Analytic_ETHa Twitter user, successfully enabled the new option in their car:

New upcoming #Tesla feature: Free access to public hotspots from AT&T, Comcast, Orange, and more! Since late last year, there have been hints in the firmware that Tesla was looking to support ‘Public Hotspots’. I was able to enable this feature, and make sure Than it works!”

He went on to provide more information about the feature in subsequent tweets: “First – for this to work, Tesla needs to enable the feature in your car. Once enabled, your car generates a TPM-based private key for use on these Wi-Fi networks.”

After that, you can just select the relevant network and the car will negotiate the connection! In the background, the firmware flags Tesla’s Product Partners with a CA version for authentication purposes, indicating that this feature stems from an upcoming partnership”

According to Analytic, the current list of supported hotspot names includes XFINITY, xfinitywifi, CableWiFi, attwifi, att-wifi, AT&T Passpoint, ChinaUnicom, CMCC, ChinaNet, KPN, KPN Fon, Ziggo, Telekom, Telekom_FON, UPC Wi-Free, Upc, UPC WifiSpots, Orange, Orange_FunSpot, SFR, SFR WiFi, SFR WiFi FON, SFR WiFi Mobile, Telia wifi1x – all are many popular providers in North America, Europe and Asia.

Although these networks are often open to the public, connection to them usually requires that the customer be subscribed to the specific Internet service provider.

Tesla cooperates with Internet providers directly giving you the ability to connect to these networks seamlessly without having to provide credentials.

These networks can be choppy at times, but Tesla will have the ability to whitelist or blacklist individual networks based on your vehicle’s location and whether the vehicle is able to connect successfully.

For owners who don’t have a premium connection, this will give them more locations to stream music and video while waiting, while charging or waiting for someone near shopping areas.

Even more owners who sign up for Premium Connectivity, this will give everyone more locations to download software updates, which are usually limited to Wi-Fi.

According to Elon, Superchargers will also get Wi-Fi connectivity in the future, giving owners even greater access.

The ability to connect to an Internet service provider with Wi-Fi access points will be a very good plus for Tesla cars, as they receive more Internet-based entertainment features.
