You can select a device that your Tesla will connect to first
Tesla
Most Tesla owners have encountered the issue of entering their vehicle only to find it connected to the wrong Bluetooth device. This inconvenience can be particularly frustrating when you're in a hurry or when multiple passengers with paired devices are present. Fortunately, Tesla has developed a solution to this widespread problem — Tesla Priority Device.
Tesla's 'Priority Device' feature allows you to select a device for your car to connect to based on the chosen Tesla driver profile. You can assign a device to multiple profiles, ensuring a smoother connectivity process for all drivers.
How Tesla Priority Device Works
When you and your spouse or child enter the car simultaneously, the vehicle will first attempt to connect to the device associated with the active Tesla profile. The closest phone to the vehicle determines your driver profile when the doors are opened. Using Priority Device helps prevent issues like your Tesla connecting to someone else's phone inside the house.
Setting Up Your Priority Bluetooth Device
To set up your Priority Device, follow these simple steps:
Go to Controls by tapping the car icon in the lower-left corner of the vehicle.
Tap the Bluetooth icon at the top of your touchscreen.
Select your preferred device.
Tap "Priority Device."
The menu will display the Tesla profiles that have your device set as their priority device. You can set your phone as the priority device in multiple Tesla profiles, including profiles such as Easy Entry.
Your car will now attempt to connect to the priority device associated with the selected profile before trying to connect to other paired phones.
Shortcomings of Priority Device
Priority Device works great, as long as the vehicle selects the correct Tesla profile. Any issues in connecting to the incorrect device are usually caused by the vehicle determining the incorrect driver profile.
If the vehicle incorrectly determines the closest phone to the vehicle, then it will select the wrong Tesla Profile and consequently, the wrong Bluetooth device to connect to.
Troubleshooting Issues
It's important to realize how the process works. Your key fob or phone key is associated with a given Tesla Profile, which can then have a Bluetooth device that it will try to connect to first.
If your vehicle is consistently connecting to the wrong Tesla Profile or Bluetooth device, you should double-check your settings.
Start by going to Controls > Locks and check that your key fob, phone key, or key card is associated with the correct driver profile.
From there, confirm that you have a Priority Device associated with each Tesla Profile by going to Controls and tapping on the user icon and name at the top of the screen. To minimize connection issues, each Tesla Profile should be associated with a priority Bluetooth device.
The Future of Tesla Priority Device
As technology continues to advance, Tesla remains at the forefront of innovation. Tesla's Priority Device feature is just one example of its commitment to improving the driving experience. Future enhancements could include more advanced algorithms for identifying the correct driver profile or even connecting to multiple devices simultaneously.
Priority Device has improved Bluetooth connectivity in Tesla vehicles, allowing for more seamless connections instead of just connecting to the first Bluetooth device it finds.

FSD’s insatiable appetite for AI compute is taking shape once again at Giga Texas, where Tesla is building out Cortex 2.0 — its second large-scale GPU supercomputer cluster — on the facility’s north side.
This confirmation comes thanks to the detailed research and findings by Giga Texas drone pilot Joe Tegtmeyer, who shared his findings on X.
For months, there has been some speculation on what this new site would be - new storage, the Optimus production line, preparation for the Cybercab’s unboxed assembly process, and more. Now, thanks to permits filed by Tesla, we know that this new area is destined to become the second supercomputer destined for FSD training.
Cortex 2.0
There are some key details we can unpack from what we’ve learned about Cortex 2.0. The new facility will be on the north side of Giga Texas, opposite Cortex 1.0, which is on the south side. The permits explicitly tie the usage of this expansion to Cortex 2.0, namely through the fact that it is a data center.
This is actually a change from Tesla’s original plans - the northern section was intended to be used as a central campus support facility, with three smaller facilities and water storage tanks. Now, it has been redesignated as Cortex 2.0 and is one large structure.
The permits that have been filed have already been approved and cover the foundations, underground water mains, and building itself. The steel structure is actively being put together on the concrete foundations, and about 50% of the roof decking is already complete, bringing the exterior shell closer to completion.
Fueling FSD’s Brain
The deployment of Cortex 2.0 is the latest in Tesla’s massive and ongoing investment in the computational power required to train FSD. While this primarily covers FSD for cars, this will also eventually apply to Optimus, which is powered by the same AI4 computer and also runs a variant of FSD.
This isn’t Tesla’s first foray into large-scale AI infrastructure and won’t be their last. Alongside Dojo, their home-grown AI supercomputer, Tesla has been partnering closely with Nvidia to ensure they have the GPUs necessary to do all the hard work. Cortex 2.0 is the next iteration, and once it's fully online, we can expect that Tesla’s work on FSD will accelerate even further.
Especially since Elon is planning something truly outrageous once again:
Been thinking about the fastest way to bring a terawatt of compute online.
That is roughly equivalent to all electrical power produced in America today.
With European Tesla owners eagerly awaiting any news on FSD in Europe, we’ve seen Tesla tease FSD, and also point out exactly what the barrier has been - regulatory approval. Now, following the latest meeting of UNECE, new regulatory amendments are set to unlock “System-Initiated Maneuvers” (SIM) on highways across participating European nations.
This development, highlighted by Kees Roelandschap on X, notes that the latest documents from the United Nations Economic Commission for Europe (UNECE) center on amendments to UNECE regulation 171. These changes were formally adopted into UNECE during the WP29 World Forum in March 2025.
Now, the amendment that will enable SIM will come into force on September 26, 2025. This six-month period after approval is standard UNECE procedure and allows objections from party states that would halt the implementation. Objections to UNECE amendments are genuinely rare, with 95% of amendments passing without objection once the World Forum adopts them.
What This Means for FSD in Europe
System-initiated maneuvers will allow your Tesla to perform actions autonomously, such as changing lanes on a highway, while the driver remains fully responsible for supervision. This is a substantial step up from current regulatory standards that only allow for suggested maneuvers or require explicit driver initiation for every automated maneuver.
This inches towards the more normal “hands-off, eyes-on” approach that Tesla has taken with FSD Supervised in North America and China. This regulatory change will help to provide the legal frameworks needed to deploy more advanced autonomy capabilities in Europe, at least matching what’s available on highways in North America.
The UNECE regulation will apply to all countries that adopt its standards, including the European Union, Japan, and South Korea - unless they specifically block it. This is a relatively positive development, but there are some hiccups.
This regulation only allows for system-initiated maneuvers on highways, not low-speed roadways. That means the city streets portion of FSD’s capabilities - including handling ‘Start FSD from Park` and reaching your destination’s parking spot - still won’t be available in Europe.
In addition, the UNECE framework has stricter requirements for driver monitoring and attentiveness - which means that some nags, including the dreaded wheel nag, are likely to remain a key portion of the experience.
Progress on autonomous driving regulations in Europe has been fraught with indecision and caution, which has been a source of frustration for many who are watching the everyday progress of FSD in North America, and more recently, in China. Even with individual countries recently approving testing of FSD on public roads, harmonized UNECE regulations are the key to wider, consistent deployment, which will allow everyday customers to use it as well.
While the path to full parity with North America may be long and involve even more regulatory machinations, the upcoming implementation of System-Initiated Maneuvers is a big step forward for Tesla owners in Europe. It is a key piece of the puzzle that will help Tesla bring some more features of FSD to Europe, assuming the September timeline holds.
