Tesla Software Update 2025.8 -- The Undocumented Changes
With most vehicles moving on to Tesla’s 2025.14 Spring Update, we’re now taking a look at all the undocumented features that were discovered during Tesla’s 2025.8 update.
While these features tend to be smaller in nature, some of them are just as valuable as the features outlined in Tesla’s release notes in the vehicle.
This update includes changes such as improvements to maps, trip meters, and Rainbow Road. Let’s take a look at all the undocumented features in Tesla’s 2025.8 software update.
New Map Icons
Icons on the map are being redesigned to be rounder and easier to see. They now feature a white border to make them pop out against a colorful background, which is especially better when using satellite views.
This feature started rolling out slowly but should now be available to everyone.
Trips & Odometer
The Trips display has been improved to show more precise information, and a new metric has been added.
More Precision: The trip meters will now show values with a tenths place when they’re under a certain value. That means that the Current Drive and Since Last Charge trip meters will now show a fractional kWh and a mile. This is especially useful for Current Drive.
The Current Drive meter is automatically reset when your vehicle comes out of park so that it can track your current drive, while the Since Last Charge meter automatically resets after a charging session completes.
More Data: In addition to added precision, the Current Drive now features a new data point. kWh is now shown for the current drive, just like the other trip meters. Previously, the Current Drive showed minutes instead of kWh -- it now features both.
These changes affect the Trips widget in the Model 3, Model Y and Cybertruck. While the added precision is also added to all vehicles under Controls > Trips, the new kWh metric for the Current Drive is only displayed in the small widget.
Additional Tool Tips
Tesla has added some additional tips to the screen that show up in certain cases. For example, if you’re playing audio over Bluetooth, Tesla will suggest that you use their built-in music apps instead of streaming through your phone.
Destination Charging
Destination charging icons are now visible on the map when you have Points of Interest enabled. You can enable Points of Interest by tapping on the map and choosing the Points of Interest icon on the right side near the satellite imagery icon.
Some destination chargers may charge a fee, while others may be open to the public or exclusive to paying customers.
Navigation Improvements
If you're using Tesla's navigation system with voice guidance enabled, the spoken directions will now stop immediately when you end the trip. Previously, the spoken directions would continue being played until the phrase was completed.
Improved Rainbow Road
The rainbow road feature has been greatly improved in this update with FSD. Rainbow road, which can be enabled in the Toybox app, now changes the vehicle's path when on Autopilot from a blue path to a rainbow one.
Previously, Tesla had to overlay the blue path on top of the rainbow colors because rainbow road didn’t support all the features of the path, such as showing chevrons when slowing down rapidly.
With this update, the rainbow path now incorporates all the same features as the blue path when FSD is active.
In addition, if you start Rainbow Road by tapping the right stalk four times, audio will play. Unfortunately, the sound couldn’t be stopped until it was completed before, but with this update, you can now stop the audio by reducing the volume with the left scroll wheel.
Additional Transparency Effects
On Intel vehicles, several modules didn't include a transparency effect. This was primarily due to Intel cars not using the blur effect since it could slow down the infotainment unit.
With this update, Tesla has enabled the transparency effect across a set of modules. Notably, this fixes the issue when using full-screen visualizations where the music player had transparency, but the navigation module on the right did not.
Transparency has also been added to other modules that are displayed over the map, such as the list of Superchargers, destinations, search results, and the ETA / End Trip module displayed at the bottom.
Note: Due to the lack of the blur effect on Intel due to performance reasons, these changes could make some text more difficult to read.
No Phone Key Graphic
The graphic that's displayed in the vehicle when it doesn't detect a phone key has been updated. Tapping on the blue text at the bottom displays the old animation showing you where to tap a key card.
Bluetooth Player
The Bluetooth app typically only displays the connected devices and a button to connect a new device. There was a lot of white space, since there wasn’t much other information to display.
With this update, Tesla is making it easier to jump to another source by displaying available music streaming services underneath the connected Bluetooth device.
Tapping a music service will jump to the selected service.
Service Mode Release Notes
As with most Tesla updates, Tesla usually adds or improves Service Mode with additional features, making diagnosing and fixing problems easier. This update adds or improves the following items.
