For everything that Teslas offer, these incredible vehicles are missing something available in nearly every other new automobile — Apple's CarPlay and Android Auto.
Apple and Google released their vehicle user interfaces back in 2014. Yet, eight years and countless requests later, Tesla still doesn't support CarPlay or Android Auto.
While Tesla's CEO, Elon Musk has never given an official explanation, there's plenty of speculation about why the dominant electric vehicle manufacturer does not support these features.
Why Tesla doesn't support CarPlay and Android Auto
First and foremost, Tesla develops its own software that is miles ahead of traditional car manufacturers.
The huge benefit that other manufacturers gain by integrating CarPlay just isn't as crucial in a Tesla, which already offers intuitive, responsive software with many features.
Many apps on a phone that would be useful in a vehicle are already available in a Tesla, from navigation, Spotify, phone integration, text messaging, karaoke, to a web browser and more. Although Tesla doesn't have a robust app store like Apple and Google, it does offer features that cover common use cases.
However, it's understandable the craving some users may have for CarPlay or Android Auto if Tesla doesn't support their favorite streaming service, such as Amazon Music, SiriusXM or even voice assistants like Siri and Google Assistant.
Although you're able to listen to music through Apple Music, and Spotify, watch Netflix and YouTube on the car's large display through Tesla's software, there will always be more options and features on a phone, regardless of how many features Tesla includes.
Seamless Experience
One reason for not integrating CarPlay or Android Auto into Teslas is that these systems would break up the Tesla experience.
CarPlay and Android Auto currently operate in their own, separate experiences. This requires you to first pull up CarPlay and then perform your desired task, such as setting your destination or switching music.
In traditional vehicles, this isn't much of an issue since CarPlay or Android Auto (AA) usually take over the middle infotainment display. This allows CarPlay or AA to remain on screen, which means that you can just tap the app you want.
However, in a Tesla, software features are very tightly integrated, and the addition of CarPlay/AA would break up the seamless experience Tesla currently offers.
For example, in a Model Y music and navigation are usually both displayed on the vehicle's screen at the same time, something that is not currently possible with CarPlay.
In addition, if the driver maximizes the music player or launches a different app in a Tesla, then Tesla displays navigation information on the left side of the screen, keeping the driver aware of the next turn.
If the driver receives a text message while driving, the driver can see and hear the message being received, regardless of which app is on screen.
However, since all of CarPlay's features only work in a CarPlay window, this kind of flexibility and integration isn't possible.
Duplicate Experience
Incorporating CarPlay or Android Auto duplicates a lot of features Tesla already has and removes the ability for Tesla to deep link apps and features.
For example, in a Tesla you could have the maps, phone, calendar, Spotify and other apps in the vehicle's launcher, giving you one-tap access to the app
For example, imagine if you had Google Maps open and you wanted to view your backup camera then open Spotify. In a Tesla, you'd tap the camera in the launcher, then tap Spotify. Two taps.
However, if you wanted to perform the same actions with CarPlay, this would take significantly longer. You'd first tap the camera icon in Tesla's launcher, then tap to go back to CarPlay, but you'd still have to go 'Home' on the CarPlay interface, then find Spotify. That's four taps, assuming Spotify was on the first page of CarPlay's home screen.
Since CarPlay acts as a secondary experience this will often increase the number of taps to get to certain information.
CarPlay also duplicates many features in a vehicle which results in some confusion since there are multiple apps for the same thing, such as navigation and music.
This issue is only exacerbated in a Tesla since Tesla offers so many of the same features as CarPlay such as maps, messages, phone, calendar, podcasts, etc.
New CarPlay Experience
Apple shows off the new CarPlay coming next year
Apple
Apple revealed a significantly improved CarPlay experience at the 2022 Worldwide Developers Conference. Emily Schubert, Apple's Senior Manager of Car Experience Engineering, said the company has "been working with automakers to reinvent the in-car experience across all the drivers' screens." The redesigned CarPlay appears much more customizable, and it's said to seamlessly integrate into vehicles instead of having a CarPlay window or taking over the entire screen.
This may be an experience that would suit Teslas much more than Apple's current offering, however, there's something else that is likely preventing Tesla from incorporating Apple's or Google's auto interface.
The Future of the Vehicle
Vehicles have traditionally been about getting you to your destination, however, that's now shifting. No one wants a car that just gets them to their desired location, they want to get there as safely as possible and be entertained on the way.
As this shift continues and we approach an autonomous future, vehicles will be much more about software and their entertainment offerings.
The next generation of car makers will not be decided by how they drive, but by how autonomous they are and what software features they offer.
Future Competition
While many pit Tesla against Volkswagen, Toyota and others, these are merely short-term obstacles for Tesla.
Tesla's true competitors have yet to emerge, but they'll be in the form of powerful tech companies such as Apple and Google. Companies that not only have strong design and AI foundations but also have access to a large user base and a dominant platform.
When a manufacturer incorporates CarPlay or Android Auto, they're giving up a great deal of control to Apple or Google.
They're not only giving up control though, they're giving up the opportunity to build a vehicle platform and a loyal user base.
If Tesla added CarPlay and Android Auto to their vehicles, they'd be helping their upcoming competitors by giving them control of a market they already know will decide the next big players - the inside of the automobile.
AirPlay
But there is another solution that may keep Apple users and Tesla happy — the use of AirPlay. This capability enables pairing a phone to an audio device to stream music or podcasts. AirPlay is not available in cars yet, but it would not be much of a leap to include the option with Tesla already equipped with Wi-Fi capabilities. Elon Musk recently left the door open for that development.
In May 2022, Musk responded to a tweet. @JacobB1290H wrote: "The speaker system in Teslas are so good, but we are limited by the quality of Bluetooth. Could we have AirPlay added? It adds the ability for lossless streaming. The hardware necessary is already there."
At least one developer has created a workaround to add CarPlay to Teslas. Michal Gapinski developed a solution that allows you to take a Raspberry Pi and connect it to your vehicle to incorporate CarPlay into the vehicle's browser.
While the solution is great, it does require some tech knowledge to get working. While this gives some users what they want, it puts even more pressure on Tesla to develop a native solution.
During the 2022 Apple event, the company stated that CarPlay is a must-have feature for people who are car shopping. According to Apple, 79 percent of buyers in the United States would only consider a vehicle that is CarPlay-capable. The company also says that CarPlay is already available in 98 percent of cars in the U.S.
These numbers put Tesla and other EV manufacturers such as Rivian in a difficult position. They understand the future of the EV, but at the same time, their users are demanding access to CarPlay and Android Auto.

For Tesla owners with vehicles equipped with Hardware 3 (HW3)—once hailed as the key to unlocking autonomy, Robotaxi functionality, and unsupervised Full Self-Driving—the landscape is quickly changing. FSD updates were previously available for HW3 and HW4, but now, HW3 is often excluded from newer FSD updates due to compute and memory constraints. While HW3 vehicles still run a capable version of FSD, they are considerably less smooth than HW4 vehicles.
This has many HW3 owners curious about Tesla’s plans to upgrade these older vehicles, which were once promised to be capable of true autonomy. Let’s take a look at everything Tesla has said and what we should expect.
The HW3 Predicament
Introduced around April 2019, HW3 was a big leap over HW 2.5 and HW 2, with Tesla billing it as the computer that would eventually deliver true self-driving. For a long time, it powered the FSD Beta program. However, as FSD Supervised becomes more complex and data-intensive, particularly with neural networks moving towards an end-to-end AI approach, questions about HW3’s long-term lifespan have grown.
While HW3 vehicles are still receiving FSD updates, with the latest version, V12.6, launching in January 2025, the latest improvements in FSD v13 appear to be stretching even the more modern capabilities of AI4 hardware. This has understandably led to concerns that HW3 will not support Robotaxis and true autonomy.
Tesla’s HW3 Upgrade Promise
To address these concerns, Elon Musk has made increasingly definitive statements. After initially suggesting an upgrade would happen "if needed," he confirmed at the Q4 2025 Earnings Call that Tesla will upgrade HW3 computers for customers who purchased the FSD package.
Musk stated, “That's going to be painful and difficult, but we'll get it done. Now I'm kinda glad that not that many people bought the FSD package, haha.”
While Musk initially stated that Tesla would offer a hardware upgrade if needed, he gave more details this time, stating that the complimentary upgrade would be available for those who purchased the FSD package. Subscribers and non-subscribers will likely need to pay a fee similar to the HW 2 / HW 2.5 upgrade. Interestingly, Tesla was later sued for charging a fee to upgrade to HW3 and had to waive the cost.
When Will the HW3 Upgrade Be Available?
Despite Musk’s confirmation of an upgrade, Tesla hasn’t provided any timelines or estimates for HW3 retrofits. The prevailing logic, and one that aligns with Tesla’s approach to engineering challenges, is that the company is unlikely to initiate a mass upgrade program until FSD is significantly closer to being “solved,” meaning it has achieved true, unsupervised autonomy where a driver is not needed.
Until Tesla knows the final, stable computing power and architectural requirements needed for that level of autonomy, rolling out an interim upgrade wouldn’t make sense. It would risk needing yet another upgrade down the line. Therefore, HW3 owners are in a waiting game - will they wait it out, or will they take one of Tesla’s FSD transfer deals?
What to Expect With the HW3 Upgrade
One thing is clear. The upgrade will not be a simple swap to the current generation of HW4 hardware. AI4, as found in newer Tesla vehicles, has different physical dimensions, power and cooling requirements, and connector configurations that make it incompatible as a direct retrofit into HW3-designed vehicles. It’d require a lot of effort and cost to adapt HW4 for HW3 vehicles.
This means Tesla will have to develop another custom-designed retrofit FSD computer specifically for HW3 replacements. This computer must fit within an existing and defined physical space and operate within the power and cooling budget of older vehicles.
Speculation naturally turns to Tesla’s next-generation FSD hardware, HW5 or AI5. Elon previously indicated that AI5 would appear in new vehicles near the end of 2025, initially citing a timeframe of 12-18 months back in mid-2023. However, it now looks like it’ll ship sometime in the first half of 2026.
Potentially, a variant of this new AI5 computer, perhaps a more power-efficient or underclocked version, could be engineered to form the basis of the HW3 retrofit solution. This is plausible, as newer chip architectures often bring considerably greater efficiency, potentially allowing a more powerful new design to operate within HW3’s constraints.
What About HW4 and HW5?
The current-generation FSD computer, HW4, is already facing some constraints with the latest FSD v13 updates. This means buyers and owners of AI4 vehicles are also starting to have this question creep into the back of their heads… “What about my vehicle?”
Based on Tesla’s official statements on AI5, it is poised to be a powerhouse of an upgrade. That means up to 10 times the processing capability of AI4. This is an immense increase in processing power, and over time, Tesla will likely use every bit of it to make FSD handle as many edge cases as possible. While AI4’s computing power was a modest increase from HW3, the leap from AI4 to AI5 is expected to be significantly larger.
Tesla’s executive team has stated that the existing cameras on HW3-equipped vehicles are “capable” and that the upgrade will be focused on the FSD computer. While the AI4 cameras offer a much higher resolution than HW3, Tesla says they’re not needed. This appears to contradict what Tesla is doing as of FSD v13.2. In that update, Tesla introduced processing FSD camera feeds at full resolution, suggesting that there is some advantage to the higher-resolution cameras.
Musk also stated that cameras would not be upgraded in HW3 vehicles.
As we’ve previously covered, the newer HW4 cameras offer several advantages over the HW3 camera generation, which include:
Higher Resolution: The AI4 cameras feature 5 megapixels, compared to the 1.2 megapixels on HW3 cameras, which allows the vehicle to see things further away and in sharper detail.
Improved Dynamic Range and Low-Light Performance: The improved dynamic range allows the system to see more clearly in low-light conditions, such as during sunrise or sunset, or at night.
Wider Field of View: The rear camera on AI4 features a significantly larger field of view, providing greater awareness of the vehicle's surroundings.
It's known that AI4 processes camera data at these higher resolutions, which undoubtedly contributes to its increased performance in decision-making, object recognition (especially at a distance or for small details, such as text on signs), and overall FSD smoothness.
Therefore, while a new, more powerful retrofit computer for HW3 vehicles will bring substantial improvements, it will still be processing input from the older-generation cameras. Another technical challenge that Tesla will need to address is how to maximize FSD performance using the existing HW3 cameras.
Infotainment (MCU) Upgrade?
Most HW3-era vehicles are equipped with the older Intel Atom-based infotainment computer, known as MCU 2. Newer Teslas, as well as newer HW3 vehicles, use the considerably faster AMD Ryzen-based MCU 3. Given that Tesla sometimes packages the FSD computer and infotainment computer together, it wouldn’t be too surprising to see an MCU upgrade as part of an FSD computer retrofit.
While this would be a welcome improvement, providing a snappier user interface and better media capabilities, Tesla has not confirmed any such plans. The FSD computer and the MCU are technically separate systems, but Tesla usually bundles them together to save on costs. While Tesla has offered paid MCU upgrades in the past (e.g., from the older MCU 1 to MCU 2), there is currently no official upgrade path from MCU 2 to MCU 3.
It’s best to assume that the promised free FSD computer upgrade will not automatically include an infotainment system upgrade as well, but it’s certainly possible, given that Tesla usually bundles these together.
Playing the Waiting Game
For Tesla owners who purchased FSD with their HW3 vehicles, the commitment for a free hardware upgrade is on the record. However, the "when" and "what" remain tied to the challenge of achieving true, unsupervised autonomy. Once Tesla understands the compute power required to solve FSD, we’ll likely hear more about this hardware upgrade. Until then, we’ll have to hold on tight with FSD v12.6.
In just 8 months, Tesla has gone from breaking ground to delivering electrons at its most ambitious Supercharger project to date, just in time to be ready for the busy Fourth of July holiday weekend. Project Oasis, the world’s largest Supercharger site, is now partially open to customers for its first phase in Lost Hills, California.
What makes this remarkable is the speed of execution. In just eight months, Tesla has constructed a site that will eventually feature 168 stalls (84 stalls are now open), supported by 11 MW of solar power and 10 Megapacks of battery storage. That construction speed is pretty impressive, but what is even more impressive is how this new station operates and what it means for future Supercharging infrastructure.
Self-Sufficient Energy Oasis
Not a Tesla App
The first 84 stalls at Lost Hills are now open, and according to the Tesla Charging team, they are currently powered solely by the sun and operate off-grid.
This makes it more than just a new Supercharger site. It serves as a proof of concept for a new type of Supercharger. Unlike nearly every other charging site in the world, which draws power from local utilities, this station generates its own clean electricity from its massive solar array and stores it in its array of on-site Megapacks.
Self-sufficient charging stations are something completely different than what we see today. They are highly resilient since they’re not reliant on the grid. That means that even if there is a local power outage, brownout, or blackout, one can always come to Lost Hills to Supercharge.
If you’ve got a Cybertruck, you could take advantage of the Cybertruck’s Powershare feature and charge up at Lost Hills to help keep your home powered during a blackout, utilizing the Cybertruck as a portable battery charger. Now that’s true independence and self-reliance.
The Future of Charging
Solar-powered Superchargers help avoid massive new loads on already stressed electrical grids, especially during peak afternoon and evening hours, when demand is the highest.
This is Tesla’s vision for the future of charging: a clean, fully closed-loop ecosystem that sustains itself. The sun’s energy is captured, stored, and delivered directly to vehicles on site at any time of day without relying on the electrical grid or fossil fuels.
Largest Supercharger in the World
This opening of 84 stalls is just the first phase of the project. Tesla says that the remaining stalls, as well as a new on-site lounge, are coming later this year. Once complete, the 168-stall site will be the largest Supercharger site in the world.
While the speed of building such a massive project in just eight months is a testament to Tesla’s execution, the true innovation is actually that self-sustainability. Let’s hope we see even more large, self-sufficient Supercharger sites across the world in the near future.
