Tesla 2020.40.0.4: Speed Assist, Glovebox PIN, Priority Bluetooth, and more
Tesla’s new 2020.40.0.4 Software Update has been released to owners, and a variety of new features were added to make life easier for drivers. Speed Assist Improvements join new security functionalities, along with fresh accessibility features to make driving a Tesla safer and more luxurious.
While the electric automaker rolls out updates in a frequent fashion, this new software comes with multiple functionalities that are entirely new to drivers. Other updates could include one or two features that are simply improvements to already existing characteristics. However, 2020.40.0.4 includes multiple features that Tesla has not included in past updates.
Speed Assist Improvements
Tesla vehicles will now use the external cameras on the car to detect speed limit signs. This will help improve the accuracy of speed limit date for highways, but it will also help vehicles travel at appropriate speeds.
In the past, some owners have complained that their vehicles are not recognizing the speed limits in certain regions. California drivers were having relatively non-existent issues with the functionality, but drivers in other parts of the United States were reporting several issues with their cars traveling at the correctly intended speeds.
Tesla poised to roll out speed limit recognition and roundabout support worldwide
CEO Elon Musk responded that the issues were of “high priority,” and that Tesla was addressing them.
It appears that the functionality has been improved and fixed. The release notes state:
“In addition to local roads, Speed Assist now leverages your car’s cameras to detect speed limit signs to improve the accuracy of speed limit data for highways. As usual, to adjust Speed Assist settings, tap Controls > Autopilot > Speed Limit.”
Additionally, drivers with different Infotainment systems will have differing capabilities.
Notes for MCU2 drivers state:
“Speed Assist now leverages your car’s cameras to detect speed limit signs to improve the accuracy of speed limit data on local roads. Detected speed limit signs will be displayed in the driving visualization and used to set the associated Speed Limit Warning. As usual, to adjust Speed Assist settings, tap Controls > Autopilot > Speed Limit.”
MCU1 users will have slightly fewer capabilities, according to their notes, which say:
“Speed Assist now leverages your car’s cameras to detect speed limit signs to improve the accuracy of speed limit data on local roads. As usual, to adjust Speed Assist settings, tap Controls > Autopilot > Speed Limit.”
The functionality is availabel on all four currently released Tesla models and requires HW 3.0 to be used.
Priority Bluetooth Device
Tesla vehicles will now connect to one Bluetooth device that has been defined as the “priority device,” according to the new update. This will stop confusion between two owners whose phones or devices are both synced to the vehicle. One phone will be considered the “priority” device, and will automatically connect. It is available for all four vehicles.
“To avoid connecting to the wrong nearby phone, you can now set your priority Bluetooth device. Your car will attempt to connect to the priority device associated with the profile selected before it attempts to connect to other paired phones. To set your priority device, tap the Bluetooth icon on the top of your touchscreen, select your preferred phone and tap Priority Device.”
Mobile App – Vent Windows
This feature is pretty self-explanatory. It is only available for the Model S, however.
“You can now vent all of your windows from the Tesla mobile app.
Note: this feature requires the Tesla mobile app version 3.10.0 or later.”
Glovebox PIN
A great security addition for owners, the Glovebox will now be locked until a four-digit PIN number is entered. A glovebox is a great place for sensitive information like insurance or vehicle titles. Tesla adding this feature should give owners peace of mind. It is available on all four cars.
“Protect the valuables in your glovebox with a 4-digit PIN. Tap Controls > Safety & Security > Glovebox PIN on the touchscreen to create your PIN.”
Charge Port Inlet Heater
Model 3 and Model Y owners can enjoy a defrosted charge port thanks to an inlet heater that will remove any ice or snow from the inside of the mechanism. It can be turned on through the Tesla mobile app, so owners won’t have to go out into the cold weather to get things cleared up for when they need to charge.
“Your car can now use the charge port inlet heater to help defrost the inside of the charge port. The charge port inlet heater can be activated in cold ambient temperatures by enabling preconditioning using the mobile app, activating the rear defrost button on the vehicle’s touchscreen, or preconditioning the vehicle using scheduled departure.”

Tesla confirmed HW3 can’t do Unsupervised FSD but there’s more to the story
Tesla confirmed HW3 vehicles cannot run unsupervised FSD, replacing its free upgrade promise with a discounted trade-in.
Tesla has officially confirmed that early vehicles with its Autopilot Hardware 3 (HW3) will not be capable of unsupervised Full Self-Driving, while extending a path forward for legacy owners through a discounted trade-in program. The announcement came by way of Elon Musk in today’s Tesla Q1 2026 earnings call.

The history here matters. HW3 launched in April 2019, and Tesla sold Full Self-Driving packages to owners on the understanding that the hardware was sufficient for full autonomy. Some owners paid between $8,000 and $15,000 for FSD during that period. For years, as FSD’s AI models grew more demanding, HW3 vehicles fell progressively further behind, eventually landing on FSD v12.6 in January 2025 while AI4 vehicles moved to v13 and then v14. When Musk acknowledged in January 2025 that HW3 simply could not reach unsupervised operation, and alluded to a difficult hardware retrofit.
The near-term offering is more concrete. Tesla’s head of Autopilot Ashok Elluswamy confirmed on today’s call that a V14-lite will be coming to HW3 vehicles in late June, bringing all the V14 features currently running on AI4 hardware. That is a meaningful software update for owners who have been frozen at v12.6 for over a year, and it represents genuine effort to keep older hardware relevant. Unsupervised FSD for vehicles is now targeted for Q4 2026 at the earliest, with Musk describing it as a gradual, geography-limited rollout.
For HW3 owners, the over-the-air V14-lite update is welcomed, and the discounted trade-in path at least acknowledges an old obligation. What happens next with the trade-in pricing will define how this chapter ultimately gets written. If Tesla prices the hardware path fairly, acknowledges what early adopters are owed, and delivers V14-lite on the June timeline it committed to today, it has a real opportunity to convert one of the longest-running sore subjects among early adopters into a loyalty story.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go
Tesla’s Optimus factory in Texas targets 10 million robots yearly, with 5.2 million square feet under construction.
Tesla’s Q1 2026 Update Letter, released today, confirms that first generation Optimus production lines are now well underway at its Fremont, California factory, with a pilot line targeting one million robots per year to start. Of bigger note is a shared aerial image of a large piece of land adjacent to Gigafactory Texas, that Tesla has prominently labeled “Optimus factory site preparation.”
Permit documents show Tesla is seeking to add over 5.2 million square feet of new building space to the Giga Texas North Campus by the end of 2026, at an estimated construction investment of $5 billion to $10 billion. The longer term production target for that facility is 10 million Optimus units per year. Giga Texas already sits on 2,500 acres with over 10 million square feet of existing factory floor, and the North Campus expansion is being built to support multiple projects, including the dedicated Optimus factory, the Terafab chip fabrication facility (a joint Tesla/SpaceX/xAI venture), a Cybercab test track, road infrastructure, and supporting facilities.

Texas makes strategic sense beyond the existing infrastructure. The state’s tax structure, lower labor costs relative to California, and the proximity to Tesla’s AI training cluster Cortex 1 and 2, both located at Giga Texas and now totaling over 230,000 H100 equivalent GPUs, means the Optimus software stack and the factory producing the hardware will share the same campus. Tesla’s Q1 report also confirmed completion of the AI5 chip tape out in April, the inference processor designed specifically to power Optimus units in the field.
As Teslarati reported, the Texas facility is intended to house Optimus V4 production at full scale. Musk told the World Economic Forum in January that Tesla plans to sell Optimus to the public by end of 2027 at a price between $20,000 and $30,000, stating, “I think everyone on earth is going to have one and want one.” He has previously pegged long term demand for general purpose humanoid robots at over 20 billion units globally, citing both consumer and industrial use cases.
Tesla (NASDAQ: TSLA) reported its earnings for the first quarter of 2026 on Wednesday afternoon. Here’s what the company reported compared to what Wall Street analysts expected.
The earnings results come after Tesla reported a miss on vehicle deliveries for the first quarter, delivering 358,023 vehicles and building 408,386 cars during the three-month span.
As Tesla transitions more toward AI and sees itself as less of a car company, expectations for deliveries will begin to become less of a central point in the consensus of how the quarter is perceived.
Nevertheless, Tesla is leaning on its strong foundation as a car company to carry forward its AI ambitions. The first quarter is a good ground layer for the rest of the year.
Tesla Q1 2026 Earnings Results
Tesla’s Earnings Results are as follows:
- Non-GAAP EPS – $0.41 Reported vs. $0.36 Expected
- Revenues – $22.387 billion vs. $22.35 billion Expected
- Free Cash Flow – $1.444 billion
- Profit – $4.72 billion
Tesla beat analyst expectations, so it will be interesting to see how the stock responds. IN the past, we’ve seen Tesla beat analyst expectations considerably, followed by a sharp drop in stock price.
On the same token, we’ve seen Tesla miss and the stock price go up the following trading session.
Tesla will hold its Q1 2026 Earnings Call in about 90 minutes at 5:30 p.m. on the East Coast. Remarks will be made by CEO Elon Musk and other executives, who will shed some light on the investor questions that we covered earlier this week.
