Tesla’s long-awaited adoption of Apple CarPlay is still happening – just not as quickly as some drivers had hoped. After signaling last year that support could arrive by the end of 2025, the electric carmaker has hit a few unexpected hurdles that are slowing the rollout, according to the latest edition of Bloomberg’s Power On newsletter.

A delayed but ongoing integration

Tesla began working to bring Apple’s CarPlay system to its vehicles amid a period of soft sales and mounting pressure to boost demand. At the time, adding CarPlay was viewed internally as more than a minor software update. For many car buyers, CarPlay has become a must-have feature – a familiar, iPhone-like interface that seamlessly integrates navigation, messaging and music into the dashboard.

Despite Tesla’s reputation for having one of the best in-house infotainment systems in the auto industry, customer demand for CarPlay has remained strong. Tesla’s software already supports Apple Music, Spotify, video playback, web browsing and deep integration with its Full Self-Driving (FSD) system. But for many users, that’s not enough. CarPlay’s simplicity and ecosystem integration remain a powerful draw.

Tesla confirmed plans to support CarPlay in a windowed mode within its existing interface. However, technical challenges have pushed the timeline back.

During testing, Tesla discovered compatibility issues between Apple Maps and its own mapping software used for self-driving features. Specifically, turn-by-turn guidance from Tesla’s navigation system did not properly synchronize with Apple Maps when autonomous driving was active. In scenarios where both systems were visible side by side, this mismatch could confuse drivers.

Tesla requested engineering changes from Apple to address the issue. Apple implemented the fix in a later update to iOS 26 and the latest version of CarPlay. But another obstacle emerged: not enough users had installed the updated software.

CarPlay isn’t just another dashboard app – it’s become a central part of how many drivers interact with their vehicles. For iPhone users especially, the ability to mirror apps, access messages, use Apple Maps or Google Maps, and rely on Siri through a familiar interface can significantly improve the driving experience.

Tesla has long resisted adding CarPlay, arguing that its own system offers superior integration

But as competitors increasingly include CarPlay as standard, the absence has been a sticking point for some potential buyers. Adoption rates of iOS 26 have been slower than previous releases. Apple recently revealed that 74% of iPhones released in the past four years are running iOS 26 – slightly behind the pace of earlier updates. Crucially, the necessary Apple Maps fix did not arrive in the initial iOS 26.0 release but in subsequent updates. Apple has not disclosed how many users are on those later builds.

For Tesla, rolling out CarPlay before a critical mass of drivers has the compatible software could create inconsistencies and support issues. That has prompted a more cautious approach.

The good news is that CarPlay remains firmly on Tesla’s roadmap. As iOS 26 adoption continues to rise, the technical barriers should gradually ease. Apple is also expanding CarPlay functionality, adding support for third-party voice chatbot apps and enhancing its premium Ultra version – moves that could make the eventual Tesla integration even more compelling.

For now, Tesla drivers eager for CarPlay will need to wait a little longer. But the direction is clear: the feature is coming – just on a timeline dictated as much by software adoption as by engineering.
