Tesla's Elon Musk shares MCU1 retrofit target timeframe, estimates $2k upgrade cost
Elon Musk has provided new details about Tesla’s Media Control Unit (MCU) retrofits for vehicles that are equipped with older infotainment systems. According to the CEO, MCU1 to MCU2 retrofits may start in a few months, though he does not personally recommend it, especially considering its estimated $2,000 cost. Musk has instead suggested that Tesla will release an update to older cars that can optimize the performance of their existing MCUs.
Musk’s recent statements were shared on Twitter while the CEO was interacting with Tesla owners, some of whom owned MCU1-equipped vehicles. The limitations of the older hardware have become more prominent over time, particularly as Tesla rolled out media-heavy features such as the Tesla Theater and the Tesla Arcade. Similar to older hardware in mobile devices, MCU1 vehicles have become slower compared to the company’s newer vehicles like the Raven Model S and X, as well as the Model 3.
Elon Musk has previously stated that MCU1 retrofits would be offered to owners whose vehicles are still equipped with older hardware. The CEO confirmed this following the initial rollout of MCU2 vehicles, and the idea was reiterated after the release of the company’s new Tesla Arcade titles. That being said, a number of Tesla owners have been informed by local service centers that an MCU1 to MCU2 retrofit was not possible.
For the uninitiated, Tesla’s MCU1 is equipped with an Nvidia Tegra 3 processor, which is capable but a tad slower than its newer sibling. Meanwhile, the MCU2 runs on an Intel Atom E800 series chip and comes with a faster browser. The unit also renders videos with sound, giving it the capability of running new features such as the Tesla Theater, which includes video streaming apps such as Netflix and YouTube, as well as video games in Tesla Arcade. All Tesla Model 3s run on MCU 2, as well as Model S and Model X units purchased after March 2018. Customers who bought their Model S and X prior to March 2018 use the MCU1.
Many Tesla owners whose vehicles are equipped with MCU1 have been clamoring for an update to avail of features only enjoyed by those using the newer system. Tesla has not left those on MCU1 in the dark and has rolled out several updates to improve the performance of the older infotainment systems. That being said, the gap between the actual capabilities of Tesla’s MCU1 hardware and its MCU2 features such are growing, and it has pretty much reached the point where the infotainment systems of older vehicles are significantly slower than those in newer cars.
In a way, Elon Musk’s recent statements hint that Tesla’s current priority is the rollout of its Hardware 3, which is essential for its Full Self-Driving initiatives. Retrofits for HW2.5 vehicles have already begun, and HW2 vehicles are expected to follow soon. HW3 is Tesla’s custom-designed computer that replaces the old Nvidia computer used for HW 2.5. As noted by Tesla during its Autonomy Day presentation, Hardware 3 was specifically built to achieve true Full Self-Driving capabilities and can enhance the electric car’s processing capability by as much as 1,000 percent.
Nevertheless, it would be wise for Tesla to start rolling out its MCU1 retrofits for older vehicles, even if it’s later than expected. Considering that Tesla owners have shown a willingness to pay for the retrofit, and the CEO himself has confirmed that the upgrade is possible, it is in both Tesla and its customers’ best interest to make sure the vast majority of its fleet are able to enjoy the best that the company has to offer — even if it’s just for infotainment purposes.
Tesla owners have long griped about the wireless phone charger in the Model Y and other vehicles. It often turns smartphones into miniature ovens rather than reliably topping them up.
Software engineer and Model Y owner Michał Gapiński tackled this issue head-on with a clever DIY upgrade, swapping the cooled wireless charger pad from the China-made Model YL in for the one that came standard in his vehicle.
There are several key differences between the U.S.-built Model Y’s wireless charging pad and the one that Tesla has been installing in the Model YL. The one installed in U.S.-built vehicles lacks active cooling and relies on basic heat dissipation, leading to rapid temperature buildup during charging. In contrast, the Model YL integrates a small fan for active cooling.

This design maintains lower temperatures even in warm ambient conditions, though it does not support faster Qi2 charging on iPhones. The connector matches exactly, making physical swaps feasible on compatible consoles, but coding is required to enable full functionality.
Owners in the U.S. have complained about the wireless charging pad, with many reporting that overheating is fairly common. Within 20 or 30 minutes of placing a phone on the wireless charging pad, many have reported overheating messages on their phones, which halt charging and essentially turn the pad into a fancy place to rest your phone.
Many owners have opted to simply plug their phones into a charging cord. Tesla has acknowledged the problem by releasing several solutions for owners, including a relatively new feature that allows you to simply turn off the charging and simply act as a holder for your phone while driving.
Gapiński said that he sourced the cooled pad affordably from China, and it cost under $200 for the part.
He removed the existing console charger, swapped in the new unit, confirming a perfect connector fit, and handled the trim differences. Since the parameter isn’t fully secured, he enabled it through custom coding outside official Toolbox.
Connector is identical, she fits, now time to code it. https://t.co/Y9idgDrpCq pic.twitter.com/uwwgq6blg7

The fan activates quietly, blending with AC and seat cooling. He reported the installation was effective and the wireless charging pad worked perfectly; it even kept the phone cool as it stayed at just 86 degrees Fahrenheit. Many times, the wireless charging pad will bring the phone’s temperature well above 100 degrees, sometimes even being relatively hot to the touch.
The retrofit worked, no issues. First Model Y with a cooled wireless charger! No QI2/faster charging on the iPhone but it does not boil the phone even when it is 30 degrees outside.
The fan kicks in, it is not audible especially with the air conditioning and seat cooling. The… https://t.co/JOyR8Tb1Yo pic.twitter.com/kJcYhQIlYq

This retrofit highlighted an elegant, owner-driven solution to a factory shortcoming. It is expected that Tesla will begin installing the cooled charging pads into new cars in the U.S. soon, and hopefully, it will offer some sort of retrofit service or kit to owners here who want to use the charging pad effectively.
For those who love to tinker, it’s an accessible upgrade, proving that innovation thrives beyond the production line.
The Tesla Roadster unveiling could be coming “in a few weeks,” according to the company’s Chief Designer Franz von Holzhausen, who said at the Tesla Takeover Europe Event in Austria that the all-electric hypercar could finally make its way to the production line after years of anticipation.
Von Holzhausen delivered the news just days after The Information reported that Tesla planned to push the Roadster unveiling to August. It was slated for both April and May of this year, but now it seems the company is leaning toward a late Summer event to cap off the heat with perhaps its most anticipated vehicle of all-time.

Franz has been with Tesla since 2008, and has played a pivotal role in the iconic design language the company has utilized with its vehicles. Speaking to the crowd in Austria virtually, von Holzhausen’s comments injected fresh excitement into a project that has been plagued by delays for nine years.
The second-generation Roadster promises to redefine supercar standards. Tesla’s website still highlights ambitious targets: 0-60 mph in under 1.9 seconds (with optional SpaceX thruster pack potentially achieving 1.1 seconds or less), a top speed exceeding 250 mph, and a range of about 620 miles.
Equipped with a tri-motor all-wheel-drive setup delivering over 1,000 horsepower, the four-seater aims to blend blistering acceleration, everyday usability, and innovative features like cold gas thrusters for short-hop capabilities, technology that will combine the project with SpaceX.
But years after the company promised to start production, which was slated for 2020, the timeline for the Roadster has continued to shift.
Tesla has strung along those who have put $50,000 deposits down, as well as fans and enthusiasts of the company who have been long awaiting the company to bring forth a car truly designed for the human driver, and not autonomy. The Roadster is more than just a halo vehicle for Tesla; it showcases the company’s ability to push the boundaries while incorporating synergies from other Musk companies.
However, it has to make it to production, which is something Musk and Co. have pushed back repeatedly.
As Tesla navigates Robotaxi development and broader autonomy goals, the Roadster serves as a reminder of its performance roots. If von Holzhausen’s timeline holds, fans could witness this engineering marvel by late June or early July 2026. Whether a full unveiling, demo, or initial deliveries, it marks a milestone for electric supercars.
Tesla has reportedly pushed the unveiling of the Roadster once again, but there are also evidently new details about the event that the company plans to show off.
The Information reported this morning that Tesla will now unveil, for the second time, the next-generation Roadster in August, a further delay from the multiple timeline that the company had previously stated.
The report has not been confirmed or denied by Tesla at any capacity.
It also states the unveiling event will take place in Texas, the same place that Tesla executives revealed in May would be the place of manufacture for the company’s highly-anticipated supercar, which boasts a top speed of over 250 MPH and 650 miles of range, according to its website.
Tesla is also expected to showcase the SpaceX package, which will be used for faster acceleration and potentially hovering capabilities, at the unveiling event, the report states. Musk has always planned for this to happen, but now it seems it is more realistic than ever

The Roadster has had its unveiling date and manufacturing date pushed back on many occasions. It was set to start production in 2020, but the COVID-19 pandemic crippled supply chain operations, forcing Tesla to push its timeline back considerably.
However, COVID has been over for some time, and Tesla has still not managed to successfully schedule and execute an unveiling event, which is something fans and enthusiasts, as well as those who have put down a $50,000 deposit, have been waiting for.
The vehicle was close to completion last year, but Musk truly wanted Lars Moravy and Franz von Holzhausen to push the limits of the Roadster. In July of last year, Moravy said:
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”
It is important to note two things: Tesla has not confirmed these details, and the company has regularly pushed these dates back. Until Tesla sends out formal invitations with a concrete date, taking any unveiling event reports with a grain of salt is a good idea.
