Tesla has added a mini player to the Model 3 and Model Y
Teslamaniacs
Tesla's holiday update, which is update 2022.44.25.1, is jammed full of goodies, many of which require a second look. There are significant changes for Model 3 and Model Y owners. In addition, some features drivers use to operate daily, have changed location, size, and functionality.
Music Player
This one may take some getting used to. There is now a new mini-player that splits the music area into two sections. A smaller module for media controls is on the bottom left of the screen. This allows the most used buttons to be closer to the driver.
Users can swipe up on the mini media player to reveal sources, including Apple Music, Spotify, Bluetooth etc. Once a source is selected, the details open up on the right-hand side of the screen for users to select songs or playlists.
The mini media player also allows users to scroll to recent and favorites, settings, and a search function can also be found in this small, reconfigured player. The mini-player will automatically collapse after a few seconds if left expanded.
In addition, Tesla has reintroduced cards that can be found by swiping on the media player in the lower left corner. Cards allow you to view your odometer, trip meter and tire pressure. You can see the new UI cards in action which we took an in-depth look at earlier this week.
Media Player in the Center
Unfortunately, the media player can not be placed back in its previous location. At least, not most of the time. If you're confused, you're not the only one. Here's a breakdown of what's possible. If the music panel is expanded to reveal your song selection, the media controls can be placed on top of that panel, but only when the mini player is hidden.
If the mini player is visible, then the song selection panel on the right will only display your songs/playlists, which does create some additional vertical room to display songs and or album art. However, there is no way to have just the media controls on the right side in a minimal sort of fashion as you could before.
Your choices for media controls are now one of three on the Model 3 and Model Y. You can have the mini player on the left side, which is essentially the new default. You can have the media controls on the right side, but only when the music selection panel is fully expanded (covering the map) and the mini player is hidden, or you can have the media controls hidden completely. If your music controls are hidden, a gray music icon appears in your launcher to bring them back up again.
This can all be a little confusing, and it'd be nice to see Tesla introduce a simple toggle to have the media controls on the left or right.
If you're viewing your tire pressure or odometer in the new UI cards, the media player will also jump back to the center area.
Navigation UI
Tesla has improved the layout of the navigation information
Teslamaniacs
Tesla has redesigned the navigation user interface (UI) layout, which improves the placement of directions, such as the next turn and other available options. Tesla has split the nav UI into two pieces. At the top of the screen will be critical information about the route, including next-turn directions.
The rest of the information, previously found at the top of the screen, is moved to the bottom. These details include travel time, destination details, and options to alter or cancel your navigation.
Both of these modules can be expanded to show more information. For example, swiping down on the top module will reveal additional turns along your route, while swiping up on the bottom module, or tapping the three dots will bring up additional route options such as adding a stop or editing your navigation preferences.
Your current location/town has also been shifted slightly. It used to be placed at the bottom center of the screen, but it's now been shifted slightly and is at the far corner of the display.
Fan Controls
You can now tap to change the fan speed and remain in Auto
Teslamaniacs
When your climate system is set to Auto, Tesla now uses a 'LO', 'MED', and 'HI' fan speed, instead of the previous 1-10 scale. The slider is now gone and replaced with buttons to decrease or increase the fan speed.
Tesla will no longer automatically turn off the Auto climate when you adjust the fan intensity. Even when the fan speed is modified, the HVAC system will remain in Auto.
Manual Mode
You can still use fan speeds 1-10 in manual mode

If you turn off Auto on your climate system, you'll still have granular access to the fan speed controls with the old 1-10 scale. You now also have the option to tap or use a slider to adjust the fan speed. A new slider will appear above the climate section, or you can tap the arrows to adjust the fan speed just like you do in Auto.
HomeLink
Tesla has made improvements to the HomeLink UI

Tesla has made improvements to HomeLink as well. When near your home location, the HomeLink icon will now display in the status bar at the top of the screen with an 'Activate' or 'Cancel' button.
The HomeLink dropdown will automatically disappear if you shift into reverse, but the option to activate your garage door will remain.
Furthermore, if you have auto-open or auto-close enabled, the status bar will now display the number of feet or meters before the garage door is opened or closed.
Video of UI Updates
There are many more additions and changes in the latest update, but these will impact the user the most. Tesla owners usually love to drive and are accustomed to seeing information displayed the same way in the exact location on the screen. So be sure to give yourself a little extra time to familiarize yourself with the new layout.

In a new video posted to X, Tesla is showing the progress of its first Lithium Iron Phosphate (LFP) cell manufacturing factory in North America. The facility, located in Sparks, Nevada, will be used to produce LFP battery cells for Megapacks and Powerwall.
However, the implications of this new factory extend beyond Tesla Energy. By on-shoring the production of these cost-effective batteries, Tesla is not only securing its energy supply chain but also opening the door to potentially reintroducing LFP-based vehicles in North America.

The immediate beneficiary of the new Nevada LFP facility is Tesla’s Energy division. LFP chemistry is ideal for stationary storage products like Megapack and Powerwall. It offers a very long life cycle, is extremely thermally stable and safe, and is significantly cheaper to produce than nickel-based batteries, partly because it contains no cobalt.
Until now, Tesla has relied on suppliers like CATL in China for these cells. A dedicated, domestic supply will enable Tesla to dramatically ramp up Megapack production to meet North America’s increasing demand for grid-scale energy. On the other hand, Megafactory Shanghai continues to utilize CATL’s LFP batteries and will support the rest of the world.
Tesla first revealed that they were planning to onshore LFP production in North America at the Q1 2025 Earnings Call, which will help them avoid costs, innovate in new technology, and insulate themselves from geopolitical supply chain risks.
A Potential Return for LFP Vehicles?
Another exciting application for Tesla is what this new factory means for Tesla’s budget-oriented lineup. For years, Tesla has been constrained in its ability to offer LFP-based vehicles in North America. While LFP packs are used in other markets for specific standard-range RWD vehicles, tariffs on important Chinese cells made it difficult to import these cells for use in North America.
With a domestic supply of LFP cells produced in Nevada, this tariff-related barrier will be mostly eliminated, pending the sourcing of lithium from a North American site. This is likely to lead to the reintroduction of LFP-based vehicles to the North American market, possibly in late 2026 or 2027.
An American-made LFP pack could lead to a more affordable base Model 3 or Model Y, or potentially help Tesla cut costs on the next-generation Affordable Model even further. This helps to give customers a lower-cost entry point without sacrificing a lot of range, and with the added benefit of being able to regularly charge to 100%.
Mega Nevada
With Mega Nevada now progressing well, Tesla is in an excellent position to continue iterating on its vertical integration and scaling Megapack and Powerwall—two of Tesla’s fastest-growing businesses—further. There are tons of benefits for consumers in the future as Tesla continues down this path, with more affordable Powerwalls for the home, cheaper electricity prices thanks to grid-forming Megapacks, and cheaper LFP vehicles.
The next major upgrade for Tesla’s in-car experience is pretty much already here - just hiding beneath the surface, awaiting the flick of a switch. According to new details uncovered by Tesla hacker Greentheonly, a fully functional version of the Grok conversational AI assistant is already present in recent firmware builds, just waiting for Tesla to activate it.
The feature, which is currently behind a server-side switch, could be enabled at any time by Tesla for vehicles running update 2025.20 and newer. The findings provide a better picture of what we already learned from Green’s breakdown on Grok last month.
Grok’s Requirements
@greentheonly on X
According to what Green determined from the latest software builds, the foundation for Grok was laid with update 2025.14, with more abilities and functionality added in 2025.20 to flesh it out. He also determined exactly which vehicles will be receiving Grok.
In terms of hardware, any vehicle with a Ryzen-based infotainment computer will receive Grok. This means that vehicles with the older Intel Atom processor will not be supported, at least initially. The underlying Autopilot hardware is not a factor, as Grok’s processing is not done in-vehicle.
Grok will also require premium connectivity or a Wi-Fi connection for the vehicle. At this point, we’re not sure whether Grok in your Tesla will also require you to sign up for SuperGrok, X Premium, or X Premium+, but Tesla is requiring you to sign into your Grok account. It’s just not clear whether the free version of Grok will work, or if you’ll need the premium version.
Grok User Experience
@greentheonly on X
Green also revealed the user interface for Grok for the first time. You’ll find many of the same features from the Grok app, but surprisingly, it looks like it’ll have a dark UI, even if you’re using light mode in your vehicle.
It appears that there will be a Grok app, likely for settings. However, Grok will largely operate in a modal, similar to voice commands, which are displayed near the bottom left corner of the screen.
There’s an on-screen microphone button, as well as drop-down menus for the voice and type of assistant you’d like to use.
Similar to the Grok app currently on mobile devices, you’ll be able to select from a set of voices and then define their personality. The available voices for now are the standard Ara (Upbeat Female), Rex (Calm Male), and Gork (Lazy Male).
There’s also a settings button, which, when expanded, allows you to enable or disable NSFW mode (including swearing and adult topics), as well as a Kids Mode, which will tone Grok down to be suitable for when kids are in the car.

How Grok Will Work (Button / Wake Word)
Users will be able to activate Grok by pressing a button, likely the same one that activates voice commands today. Grok will then remain enabled for the duration of your conversation, allowing you to go back and forth, asking and answering questions. To end your conversation, you’ll press the mic button again.
While it doesn’t appear to use a wake word yet, Green says that some code refers to a wake word, so it’s possible that this could be an option Tesla plans to activate in the future.
Replacing Voice Commands
The most significant implication of Grok’s future integration is in its potential to fully replace the existing and relatively rigid voice command system. Green notes that internally, this feature is part of the car assist module, and that eventually, the plan is for Grok to take over car control functions.
Unlike the current system, which requires specific phrases, a true conversational AI like Grok can understand natural language. This will enable more intuitive requests, completely changing how drivers interact with their car.
Language Support
@Greentheonly/X
Grok will also launch with multi-language support, similar to its current abilities in the Grok app. Green says that it already appears to have support for English and Chinese and one or two other languages.
Release Date
Grok appears ready to go from a vehicle standpoint, but Green wasn’t able to actually test it out. While development appears to be nearly complete in the vehicle, Tesla and xAI may still be working on some server-side changes to better integrate with the vehicle. If they plan for Grok to replace voice commands on day one, then it’ll need to be trained and be able to execute a variety of vehicle commands.
It’s possible Tesla is actively testing Grok or adding server-side changes to replace voice commands. However, it looks like vehicle development is nearly complete and Grok could launch as soon as the next major Tesla update, which is expected to be update 2025.24.
