Tesla rolls out 2020 Holiday Update: New Driving Visualizations, Supercharger Display Improvements and more (Release Notes)
Tesla is beginning to roll out its highly anticipated over-the-air 2020 ‘Holiday Update’ that includes new driving visualizations for Full Self-Driving, new games, and an improved display for Supercharger and Vehicle Information, among others.
The following are some of the most notable aspects of Tesla’s 2020 holiday update as part of Firmware 2020.48.25.
Arguably, the Tesla community fan-favorite comes in the form of a new “Boombox” feature that enables the much-talked-about Snake Jazz and Goat easter eggs.
Vehicle Information
Tesla has removed the Tesla “T” from the top menu, which provides better use of the touchscreen display’s real estate. Display improvements can be seen throughout much of the 2020 Tesla Holiday Update.
“The Tesla ‘T’ has been removed from the top status bar. Tap Controls > Software for the same information.”
Release Notes Improvements
Release notes can be accessed under the controls menu. Each feature has been itemized into a tabular left menu that provides quick access to the description for previous and current features.
“Release notes now include improved browsing and access. To view current and previous release notes, tap controls > Software > Release Notes.”
Driving Visualization Improvements
Improved driving visualizations to support Full Self-Driving capabilities take center stage in this year’s highly-anticipated Tesla Holiday Software Update.
“The driving visualization has been refreshed and now offers a larger visualization to allow drivers to view more details of the road surroundings. The next turn will now appear above the visualization if the navigation turn list is covered by another app.
Additionally, select items have slightly moved but will continue to look and behave the same. Some notable differences include the following:
- Quick access to the backup camera and wipers has moved to the bottom bar.
- Indicator lights have been moved to the side of the touchscreen.
- Autopilot set speed, Autopilot availability, and detected speed limit are now displayed next to the driving speed.”
Scheduled Departure Improvements
A refreshed look for the “Scheduled Departure” feature, previously known as “Smart Preconditioning” and released in October 2019, puts more emphasis on a simple design for easier control of charging costs and interior comfort when ready to drive. Tesla notes that Scheduled Departure can operate even when the vehicle is unplugged.
The previous language of not being functional below a 20% battery state of charge is no longer visible.
“Schedule departure can now precondition your battery and cabin even when your car is unplugged. To account for different utility rate plans, you can now set the time when your off-peak rates end to save on charging costs. To access, tap SCHEDULE from the climate control or charging panel when parked.”
Supercharger Display Improvements
Real-time Supercharger occupancy information was rolled out nearly 4 years ago (see version 1.0), and since then Tesla has continued to make user experience improvements for drivers looking to quickly access information from their touchscreen for distraction-free driving. This includes the ability to see available charging stalls at-a-glance and without the need for unnecessary taps of the touchscreen.
“Supercharger pins on your touchscreen will now display the number of available stalls at charging sites. Quickly search for nearby amenities by tapping an amenity icon on the Supercharger popup display.”
Tesla has replaced the iconic Tesla Supercharger lightning bolt icon with a number that denotes the number of currently available chargers at the location.
Emissions Testing Mode Improvements
How can one improve upon Tesla’s famed “Emissions Testing Mode”, better known as “Fart Mode”? Fart at strangers.
“Emissions Testing Mode can be used outside the car. To setup, select your desired sound and place the cushion on the external speaker. When ready, play selected sound by pressing the left scroll wheel button or using the turn signal. To access, tap the Application Launcher > Toybox > Emissions Testing Mode.”
Boombox
Elon Musk has made good on his promise to give Tesla owners the ability to entertain crowds and passersby through honking-fart and goat sounds, plus more.

In addition to several new out-of-the-box sound clips that blast out of Tesla’s exterior speaker, the latest Boombox feature enables the upload of five custom sounds.
“Turn your car into a boombox and entertain a crowd with your media player when parked. You can also customize the sound your car makes when you press the horn, drive the car or when your car is moving with Summon. Select an option from the dropdown menu or insert your own USB device and save up to five custom sounds.”
Tesla Arcade: New Games
Tesla launched a series of new games for its Tesla Arcade collection, including The Battle of Polytopia, Cat Quest, Solitaire, and Boombox.

- Cat Quest
- Solitaire
Last month, Elon Musk teased the community when he tweeted about this year’s holiday software update. Musk hinted that 2020’s holiday update would be “lit.” He also mentioned that the highly-anticipated update would include features that customers wanted, and some that they didn’t even know they wanted.
Last year, Elon Musk and the Tesla team outdid themselves with the holiday software update. Tesla’s 2019 holiday update included a sneak preview of the company’s Full Self Driving suite, TRAX v0.1, and introduced new games to the arcade, such as Stardew Valley and Lost Backgammon.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”

One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.

Tesla updates Cybertruck owners about key Powershare feature
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
