Tesla has long equipped its vehicles with LTE (4G) modems, including the new Model Y, Cybertruck, and new Model 3. However, all three models now appear to be transitioning to a new, 5G-capable modem.
This marks a first for Tesla, and it’s likely that the upgraded modem will be integrated into newly manufactured vehicles as supplies become available. The modem, listed as “TELEMATICS CONTROL UNIT - TCU - GEN II,” was spotted in Tesla’s Electronic Parts Catalog (EPC) by well-known Tesla hacker Green on X.
Faster Speeds, Where Possible
5G coverage remains limited in many areas, with rural and suburban regions still relying on LTE—or even 3G in some cases. Since around 2018, every modern Tesla has been equipped with the Gen I modem, which supports LTE speeds ranging from 20 Mbps on the low end to 100 Mbps at peak performance.
The new Gen II modem, where supported, will enable 5G speeds of up to 1 Gbps (1000 Mbps). While this will be most effective in urban areas with dense 5G transmitter coverage, it will also benefit some well-developed suburban regions.
New Model Y
Interestingly, the new Model Y may come with either a Gen I or Gen II TCU, meaning buyers won’t know which modem they’re getting until they receive the vehicle. Green confirmed on X that both the LTE-equipped Gen I unit and the new 5G-capable unit are valid configurations for the new Model Y.
Retrofits
Not a Tesla App
While Tesla now offers direct-to-customer parts sales, the EPC does not list a price for either the LTE or 5G-capable TCUs. This is because these units require programming by Tesla Service or a trained technician and must be paired with a SIM card linked to the vehicle’s VIN.
Although the hardware swap itself is expected to be relatively straightforward, this isn’t something owners can retrofit on their own. However, Tesla may offer a retrofit service in the future. For now, with parts still in limited supply, pricing remains uncertain.
If 5G support becomes essential, you might be able to request a TCU retrofit through Tesla Service in the coming months as availability improves.
When Tesla vehicles were equipped with 3G-only modems, Tesla offered a paid retrofit to an LTE-capable modem, but this was mostly due to AT&T shutting off their 3G network, and these vehicles would lose their cellular connection otherwise.
Ultimately, this news of the 5G modem confirms that Tesla remains committed to cellular connectivity in its vehicles—at least for now. Direct-to-satellite Starlink support isn’t here yet, but we’re still hoping for it in the future. Until then, a Starlink Mini strapped to your Tesla’s glass roof remains a solid alternative.

The road to bringing FSD to Europe has been a long and complex one and filled with regulatory and bureaucratic hurdles. Elon Musk, as well as other members of Tesla’s AI team, have previously voiced their grievances with the regulatory approval process on X.
However, it appears that there is finally some progress in getting things moving with recent changes to upcoming autonomy regulations, but the process still seems slow.
Waiting on the Dutch
Elon commented on X recently, stating that Tesla is waiting for approval from Dutch authorities and then the EU to start rolling out FSD in Europe. Tesla is focusing on acquiring approvals from the Dutch transportation authority, which will provide them with the platform they need to gain broader acceptance in Europe. Outside of the Netherlands, Tesla is also conducting testing in Norway, which provides a couple of avenues for them to obtain national-level approval.
The frustration has been ongoing, with multiple committee meetings bringing up autonomy regulation but always pulling back at the last second before approving anything. The last meeting on Regulation 157, which governs Automated Lane Keeping Systems, concluded with authorities from the UK and Spain requesting additional time to analyze the data before reaching a conclusion.
Tesla, as well as Elon, have motioned several times for owners to reach out to their elected representatives to move the process forward, as it seems that Tesla’s own efforts are being stymied.
This can seem odd, especially since Tesla has previously demoed FSD working exceptionally smoothly on European roads - and just did it again in Rome when they shared the video below on X.

DCAS Phase 3
While the approval process has been slow, Kees Roelandschap pointed out that there may be a different regulatory step that could allow FSD to gain a foothold in Europe.
According to Kees, the European Commission is now taking a new approach to approving ADAS systems under the new DCAS Phase 3 regulations. The Commission is now seeking data from systems currently operational in the United States that can perform System-Initiated Maneuvers and don’t require hands-on intervention for every request.
This is key because those are two of the core functionalities that make FSD so usable, and it also means that there may not be a need to wait years for proper regulations to be written from scratch. Now, the Commission will be looking at real-world data based on existing, deployed technology, which could speed up the process immensely.
What This Means
This new, data-driven regulatory approach could be the path for Tesla to reach its previous target of September for European FSD. While the cogs of bureaucracy are ever slow, sometimes all it takes is a little data to have them turn a bit faster in this case.
Alongside specific countries granting approval for limited field testing with employees, there is some light at the end of the tunnel for FSD in Europe, and hopes are that a release will occur by the end of 2025. With Europe now looking to North America for how FSD is performing, Tesla’s Robotaxi results could also play a role.
Tesla’s marketing has always been relatively unconventional, relying on word-of-mouth rather than traditional advertising. The passion of the owner’s community is always massive, but it is especially high now with the launch of the Robotaxi network just around the corner.
Tesla is now tapping into that spring of fan creativity and announced the TeslaVision video contest, with some seriously impressive prizes up for grabs.
Announcing the TeslaVision fan video showcase
Tesla owners & supporters have always been able to see our products & mission for what they truly are.
Your word of mouth has made Tesla what it is today.
The OGs will remember that in 2017, we held our first video contest. 8 years… pic.twitter.com/6pPpkqmqOH
The core of the contest is simple. Create a video that shows how your Tesla gives you more in life. Tesla is looking for submissions that highlight themes of freedom, safety, fun, and convenience.
Prizes
The prizes definitely make this contest worth entering if you’re good with a camera and have some basic video editing abilities.
For North America, the prizes include a brand new Model Y AWD Long Range, alongside an all-expenses-paid trip to Austin for a tour of Giga Texas. The grand prize winner will also be able to custom order their Model Y, allowing them to select their preferred wheels and color.
The two runners-up won’t get a Model Y, but they’ll also enjoy an all-expenses-paid trip to Giga Texas for a tour of the factory.
The travel and tour include lodging in Austin for 2 nights, as well as economy-class round-trip tickets from anywhere in North America. Tesla will also provide a vehicle for use during the trip.
For long-time followers of Tesla, this contest may feel familiar. The contest is a direct throwback to the 2017 Project Loveday contest, which was inspired by a letter to Tesla from a 10-year-old aspiring marketer. That contest was won by MKBHD, with his submission below:
