July 23, 2025

By now, we should have all received Tesla update 2025.20, and some of us have already received 2025.26. While Tesla update 2025.20 was much smaller than we’re used to, it included some useful features for some, such as the expansion of Child Left Alone Detection, Camera Updates for the HW4 Model Y, and easier charger cable unlatching in certain regions.

However, it also include more than a handful of undocumented changes that improve upon current features. Lets take a look at all the lesser, undocumented changes of update 2025.20.

PIN to Drive

Not a Tesla App

If you use the PIN to Drive feature, the PIN is now required, even if vehicle access to drive was granted through the remote start feature of the Tesla app. Previously, if you granted permission to start the vehicle, it would bypass the Pin to Drive security feature.

Trunk Open Warning

@FCastrillo86

Similar to the frunk warning added in a previous update, Tesla will now warn you when you have your trunk open and shift the vehicle into drive.

Drivers will be able to acknowledge that the trunk is open and continue driving, or they can choose to automatically close the trunk.

Note: This feature is only available on powered trunks.

Improved Energy App

@TeslaNewswire

The Energy App can now display the average speed of the Tesla fleet for a given route under certain conditions. It’ll also display how much energy you can save by slowing down.

For example, it’ll say, “This route is typically driven at 66 mph. Slow down by 5 mph and save 1% for the rest of the trip.”

Orange Dot When Using Voice Commands

Not a Tesla App

When using the voice command feature, Tesla will now display an orange dot near the speedometer, letting users know that the vehicle is actively using the microphone.

Tesla previously displayed the orange dot whenever the vehicle was using the microphone to gather audio data for FSD.

Dashcam Viewer Wider View

@little_nipas

The updated Dashcam Viewer now includes a button to switch between the full, uncropped video or the regular view.

The difference between the two views is minor, but if you’re trying to identify something during a Sentry Mode event, it could be useful to have the full, uncropped video.

This is available on HW3 and HW4 vehicles, but since it relies on the new Dashcam Viewer, it requires the AMD Ryzen processor. Update 2025.26 further improved this feature, ensuring that the buttons at the top of the Dashcam Viewer do not block the video. Update 2025.26 also adds the ability to choose playback speeds, varying from 0.5x, up to 2x.

Blind Spot Camera

@max_bracco

You can now use the blind spot camera while the Camera app is open. Previously, you could not have the Camera app and the blind spot camera view open at the same time.

Dashcam Viewer Multi-Delete

In Tesla’s recently updated Dashcam Viewer, you can now delete multiple Dashcam or Sentry Mode videos at once. Simply tap the three dots […] in the top right corner and select the clips you’d like to delete.

This feature is limited to the new Dashcam Viewer that was added in update 2025.14 for Ryzen-based vehicles. The new Dashcam viewer features multiple cameras along the bottom and includes a mosaic view that allows you to view several cameras simultaneously.

Privacy Section Now Lists Microphone

Not a Tesla App

Tesla has now added the vehicle’s use of the microphone during voice commands to the privacy section under Controls > Software > Camera and Mic.

Note: Tesla does not transcribe audio in the vehicle and instead sends the audio clip to its servers to be transcribed.

Service Mode Improvements

Tesla has added a two Service Mode improvements in this update, which include:

New A2B Audio System Panel

A new Automotive Audio Bus (A2B) Audio panel is available to support Audio system diagnosis relating to the A2B bus. It adds the ability to view the expected nodes on the A2B bus along with details of detected conditions.

Models: Model 3 (2024+) and Model Y (2020-2024) with AMD Ryzen Infotainment Processor.

Noise Recording Panel Updates (Service Mode Plus) - Available on Info-Atom and Info-Ryzen

The Noise Recording Panel is now available on all vehicles equipped with Info-Atom and Info-Ryzen Infotainment hardware. This panel adds the ability to record powertrain noise using the vehicle microphones and related vehicle metrics. The recordings can also be downloaded to a computer using a dedicated action, and the recordings are deleted when exiting Service Mode.

Models: Model S (2012-2020), Model 3, Model X (2015-2020), and Model Y

Available on update 2025.20.3 and later. This was previously added for the Cybertruck in update 2025.14.

The Next Update

That’s it for the undocumented features of 2025.20. If you found one that isn’t listed, please let us know. You can also take a look at the undocumented features we are currently aware of in the next Tesla update.

Tesla Starts Offering FSD Transfer in Europe and Middle East

Tesla’s FSD Transfer offer has been sporadically available in North America for several years, commonly used as a lever to increase sales at the end of a quarter. Tesla last offered FSD Transfer in North America in April of this year and it’s an ongoing offer today. However, the offer has always been limited to North America.

Several days ago, Musk responded to a post on X, saying it would be fair to offer it in Europe as well. Tesla has now quickly followed up on Musk’s post and has now started offering FSD Transfer in Europe and the Middle East. Tesla made the announcement on X (below).

You want it, you got it

Transfer FSD capability from your current Tesla to your new one

Now applicable to all new orders in Europe & the Middle East

Other Regions

While it’s great to see FSD Transfer offered in more regions, it’s interesting that Tesla didn’t expand this offer to all regions. With FSD coming to Australia and New Zealand and already deployed in China, they may be limiting it to markets where FSD is still not available and may not be for some time. However, that doesn’t match with their philosophy in North America.

It’s possible that we may see a similar offer in China and the Oceania region in the future.

How FSD Transfer Works

The offering of FSD Transfer is relatively simple. Owners with a vehicle with FSD simply need to place an order and take delivery of a vehicle while the promotion is active.

During the ordering process, do not select FSD on your new vehicle. Instead, inform your sales advisor that you wish to transfer FSD from your old vehicle to your new one.

FSD will be deactivated on your old vehicle on delivery day, and it will be activated on your new vehicle the same day. You are not required to trade in your original Tesla, nor required to sell it, but the license for FSD is moved completely to your new vehicle, leaving your vehicle without anything or limited to Basic Autopilot — depending on when you bought it.

This is a major benefit for loyal owners, as it saves them from having to purchase the pricey FSD package a second time, especially since they may have never been able to use it, besides some Enhanced Autopilot features such as Smart Summon.

This also comes at a time when Elon Musk and Tesla, as a whole, have continually expressed frustration with European regulators' slow progress on autonomy regulation. The last update we saw was in mid-June, when Dutch regulators were considering further deployments of FSD.

It’ll still be a while before FSD hits European streets, but at the very least, European (and Middle Eastern) customers can be happy with their new HW4 vehicles, which will be ready to receive and use the latest versions of FSD once it’s released in those regions.

Tesla Plans Diner Global Expansion; Next Location: Starbase

July 22, 2025

Just as the first Tesla Diner opens its doors in Hollywood, Elon Musk has confirmed that this is the beginning of a larger vision for the retro-futuristic Supercharger and Diner sites. If the first location is successful, Tesla plans to roll out the Diners globally to major destinations.

The second location for a Tesla Diner has already been confirmed. Tesla will be building its second diner at Starbase, Texas - home of SpaceX. That means that this isn’t a one-off project anymore, but instead something that could become a new side business for Tesla Energy - integrating food and entertainment options at major Supercharger sites in urban cores.

An Island of Good

The future vision of the diner concept is fairly clear. Tesla plans to create fun, inviting environments around some of its biggest Superchargers, removing some of the stigma around charging an EV.

If our retro-futuristic diner turns out well, which I think it will, @Tesla will establish these in major cities around the world, as well as at Supercharger sites on long distance routes.

An island of good food, good vibes & entertainment, all while Supercharging! https://t.co/zmbv6GfqKf

The Tesla Diner in Hollywood is already drawing a steady flow of street traffic, including non-Tesla owners, who come to try the food and enjoy the entertainment. There’s a lot to like about what Tesla is doing. Tesla is using healthier ingredients, serving food on roller skates, and even including tips with each purchase, helping alleviate the ‘tip-everything’ culture in the U.S.

That’s not to mention Tesla’s impressive integration of the Tesla Diner with its own app and the vehicles. For example, not only can you order from within your vehicle and pay with your Tesla account, but if you choose a pickup order, the diner will know when you arrive and which Supercharger stall you’re in.

With an experience like that, the Diner is becoming a tourist destination, more than just a simple charging spot.

Starbase and Beyond

For the next expansion, Elon said ‘Ok’ to adding a location to Starbase, Texas. If you’re not familiar with Musk’s OK responses, you’ll know that’s his way of agreeing to something. However, it likely won’t just be Starbase. If the diner is successful, then Tesla will expand the diner concept globally, adding them to major cities.

This is the Tesla way of advertising. Instead of traditional advertising that yields a low return, Tesla invests its money in ways that improve the Tesla ownership experience, while also helping to spread the word. The same can be said about adding games or ambient light features to Tesla vehicles. Tesla spends time developing features that will get people talking about the company and its cars.

Ok
— Elon Musk (@elonmusk) July 21, 2025

Thousands of space enthusiasts travel to Cyber Beach and the surrounding areas of Starbase to witness SpaceX launches every year, making it an easy decision to capitalize on this opportunity.

With the Hollywood location now finally open, its success will be the determining factor for the pace at which Tesla builds additional Drive-In Diners. But with the next location already planned, it’s clear this is more than just a small side quest now - it’ll be about turning some Supercharger sites into a one-of-a-kind experience around the world, letting many experience Tesla for the first time.
