Tesla has released software update 2025.2.6, and while minor updates typically focus on bug fixes, this one introduces a major new feature. With this update, Tesla has activated the in-cabin radar, a sensor that has been included in some vehicles for more than three years but remained unused until now.
Why Not Vision?
Unlike vision-based systems, radar can precisely measure object dimensions and even detect movement behind obstacles by bouncing radio waves off surrounding surfaces. This allows for more accurate and reliable measurements of objects that vision may not even be able to see, such as behind the front seats.
What Tesla Announced
Tesla recently highlighted the 4D radar in the new Model Y, explaining how it will improve passenger safety. Tesla executives stated that the radar would be used to properly classify passengers and improve the way airbags deploy.
Tesla went on to say that in a future update, Tesla will use the in-cabin radar to detect any potential passengers left in the vehicles. Since radar can even pick up on heartbeat and breathing patterns, it can provide a much more accurate method of detecting children left in a vehicle. Tesla talked about how the vehicle will send owners a notification via the Tesla app and enable the HVAC system if it detects a passenger in the vehicle. It’ll even call emergency services if needed.
New Feature in Update 2025.2.6
Tesla has officially named this feature in update 2025.2.6, “First-Row Cabin Sensing Update,” which appears to align with the first portion of what Tesla discussed in the new Model Y video.
In the release notes, Tesla describes the update as:
“The first-row cabin sensing system has been updated to use cabin radar, which is now standard in all new 2025 Model Ys. Your Model Y was built pre-equipped with the necessary hardware, allowing Tesla to also bring this technology to your vehicle.”
For now, it appears that Tesla is using the radar to detect and classify passengers in the front seats. This could eventually replace traditional seat sensors, reducing the number of hardware components and lowering production costs.
Tesla plans to expand the feature later this year, bringing rear-seat passenger detection in Q3 2025. While Tesla talked about the feature for the new Model Y, we expect it to be available for all vehicles with the in-cabin radar.
Supported Models
Although Tesla is vague in their release notes, this feature is being added to all Model Ys that include a cabin radar. Tesla started including the cabin radar in 2022, but its availability may vary by region and model. The Model 3 didn’t receive the cabin radar until it was redesigned in 2024, while all Cybertrucks already include it.
The owner’s manual for the redesigned Model S and Model X doesn’t specifically mention the interior radar, although Greentheonly believes the vehicles also include one, so we’ll have to wait to determine whether those vehicles also receive this new feature.
At this time, the feature appears to be only going out to Model Y vehicles, but we expect it to become available on other supported models soon.
We love to see these kinds of updates. Tesla is increasing the safety of existing and new vehicles through a software update while also making them more affordable to own.

Tesla has updated the Tesla app to version 4.42.0, and this time, it’s more than just bug fixes. The app includes a new service interface, introduces support for the new Model Y, and, for the first time, includes some code for the Robotaxi coming later this year.
This update was released for iOS and should be available on Android within a few days.
Refreshed Model Y 3D Model
First up in the update is the introduction of the 3D model for the refreshed Model Y. Interestingly, while we all know it as Juniper, the file code name inside the update lists the vehicle as “Bayberry.” The Bayberry name was introduced in Tesla app update 4.41.5. Tesla’s internal code names sometimes change as the vehicle evolves - and we’ll continue to refer to it as the refreshed or new Model Y for ease of understanding.

As usual with Tesla’s 3D models in the app, there’s a lot of detail, although it’s not easy to see since you can pinch and zoom the model in the app. The 3D models used in the app are actually the same models that Tesla uses in the vehicle, although sometimes they include different lighting effects, but they’re all highly detailed.
Robotaxi API
Tesla has added a new endpoint in their app for Robotaxi - and it’s the very first Robotaxi or Cybercab-related item we’ve seen in the app. With the Robotaxi fleet launching in June, according to Tesla, it looks like they’re now adding support to the Tesla app.
What the Robotaxi interface is supposed to look like in the future.
Not a Tesla App
The new app API is called “rides_feedback_upload,” which seems pretty explanatory. Tesla will need to gather a lot of information on ride quality and all the little things in between. What better way than to get feedback directly from users?
While Tesla previously released prototype images of what the Robotaxi app will look like, the introduction of this API into the Tesla app leads us to believe that Tesla will utilize the current app for Robotaxi use.
Updated Service Interface
The Updated Service Panel in the Tesla App
Not a Tesla App
Tesla has released an updated UI for the Tesla Service panel, and we have a ton of details on these changes. This new pane displays appointment details more prominently. If you have a service appointment scheduled, you’ll now see a lot more details on the main service screen. The app will now display:
Your current service status
Appointment date and time, which you can now tap on to add the event to your calendar
Address and hours of the service center. You can now also tap on the address to open up the location in your maps app
There’s also a new appointment details screen (the right portion of the image). This screen displays additional details that were previously unavailable, such as your transport type. The app will display whether you’ll get a loaner vehicle, demo vehicle, or something else.
There are a ton of user experience (UX) improvements in this update regarding service, including clearer language, improved UI fixes to images, and more.
Tesla has been making a lot of positive updates to the Service-related sections of the app lately, and we’re happy to see these coming rapid-fire. Tesla Service is now easier to use and understand. In the previous app update, Tesla also added the ability to pull down to update the service screens.
While Tesla supports a variety of music streaming services, including YouTube Music, Apple Music, and Spotify, there may be times you want to listen to music from a local USB drive.
While Bluetooth is also an option, it’s limited to what’s available on your phone and the lower streaming quality of Bluetooth.
In this guide, we’ll go through the benefits of having music on a USB drive and how to set it all up.
Benefits of Music on a USB Drive
Having music stored locally has several benefits. First is audio quality; since you’re under full control of the bitrate of the content, you can encode or buy music at much higher quality when compared to steaming content from Spotify or another streaming service. Tesla even supports FLAC’s lossless audio, letting you experience the best audio experience in your vehicle.
Local music also doesn’t require an internet connection, so if you frequently traffic through areas with a spotty connection, you may prefer to have music locally on hand.
While streaming content is convenient, you can be limited by the content that’s offered. If you prefer foreign music or other music that’s not available on a music service that Tesla supports, local content could be a great option.
Lastly, having music on a USB drive is a great option if you don’t subscribe to a music streaming service or don’t pay for Premium Connectivity in your Tesla.
Step 1: Use the Right USB Port
Not all USB ports in a Tesla support data transfer. While some models have USB data ports in the rear console or center console, they do not support media playback and can only be used to charge a device.
Instead, your best bet is to use the USB port inside the glovebox, which is designed for both dashcam video storage and music playback. While some vehicles may also support data transfer through the USB ports in the front console, not all of them do. Older vehicles may not have a USB port in the globebox, and you’ll be limited in using the USB ports in the console.
Important: You cannot play music from a phone, tablet, or external music player over USB—only from a properly formatted USB storage device.
Step 2: Format Your USB Drive
Every new Tesla comes with a high-speed USB drive pre-installed in the glovebox, formatted for Sentry Mode and Dashcam storage. If your vehicle didn’t come with one, or you want to use a larger or separate drive for Sentry Mode or music, you’ll need to format it first.
How to Format a USB Drive in Your Tesla
Insert your USB drive into the desired USB port.
Navigate to Controls > Safety > Format USB Drive
Wait a few seconds (it may take longer for large drives), and the system will format the drive and create the necessary folders (e.g., for Sentry Mode and Track Mode).
💡 Tip: Use a high-speed, high-capacity SSD for the best experience. Regular flash drives work, but SSDs provide faster loading times and more capability.
Step 3: Add Your Music
Once your USB drive is formatted, unplug the USB drive from your Tesla and connect it to your computer to add your music files.
Organizing Your Music:
Create a folder called Music at the top level of the USB drive. All music must be added to this folder.
You can organize the music however you prefer, and you’ll be able to view the folders in the vehicle when selecting music. Most users prefer to have folders that include the name of the artist with subfolders for the album name, but how you organize the content is completely up to you.
If your music files content metadata such as song title, artist, album, etc, it will automatically be displayed in Tesla’s media player.
Supported Audio Formats
Tesla’s music player supports a variety of audio formats, including wave, MP3, and FLAC (lossless), but it does not support AAC (Apple's iTunes format). If you have AAC files, you can convert them to MP3 or FLAC before transferring them.
Step 4: Play Your Music
Not a Tesla App
Once you’ve transferred your music, you can bring it back to your Tesla.
Insert the USB drive into the front console or glovebox port.
You’ll now have a new app under the all apps menu called USB.
The USB app will let you view all of your supported audio content on the USB drive. You’ll be able to view the content by song, artist, album, genre, and folder structure.
First-time indexing of audio content may take a few seconds (longer for larger drives). Tesla re-indexes the drive every time the car wakes from sleep, so keeping the total file size under 30GB ensures faster access.
Voice Commands and Search
While music stored on the USB drive will behave much like other content that’s played over streaming services, there are a few limitations.
Voice commands can not be used to play a specific song or artist from your USB drive. If you ask the vehicle to play any content, it’ll default to one of the music services.
Music search is also not supported. While search will show content from all music services that aren’t hidden, it will not include music from your USB drive.
Enjoy the Best Sound Tesla Has to Offer
Tesla’s audio system is meticulously engineered for a premium sound experience, and playing lossless audio over USB takes full advantage of that. If you’re an audiophile, this setup ensures you hear your music in its purest form—no compression, no interference, just crystal-clear sound.
