ZDNET’s key takeaways

• ChatGPT can now integrate directly with Apple CarPlay.
• Carry on a full, hands-free conversation with ChatGPT in the car.
• You need iOS 26.4, the latest version of the ChatGPT app, and CarPlay.

As an iPhone owner, Siri is my go-to voice assistant when I’m driving and plugged in to Apple CarPlay. Though Siri can usually handle simple tasks, it often struggles with more complex or challenging questions. But now I can easily turn to ChatGPT when I need information that Siri can’t supply.

Rolled out on Thursday, the new ChatGPT integration with Apple CarPlay lets me carry on a back-and-forth voice conversation with OpenAI’s AI when I’m behind the wheel. I can ask for information or discuss any topic I normally would pose to ChatGPT. And with minor tweaking, I can do all this work hands-free.

How to use ChatGPT with CarPlay

First up, you naturally need a car that supports CarPlay. My 2025 Toyota Camry came with CarPlay; that’s one of several reasons I chose that make and model. You must also have the latest version of the ChatGPT app. If you don’t have the app, head to the App Store on your iPhone to grab it. If you already have it, tap your profile icon in the App Store app, choose Updates, then download the latest version of ChatGPT.

Further, your iPhone must be running iOS 26.4 or later. This version of the mobile OS added CarPlay support for third-party AI chatbots like ChatGPT, Google Gemini, and Claude. This integration means that you can speak directly to any supported AI hands-free. The companies behind each AI need to tap into this new support, with OpenAI apparently first to move.

ChatGPT has long been available on the iPhone through Apple Intelligence and Siri. If Siri can’t answer a question, it can pass along your request to ChatGPT. You can also tell Siri to ask ChatGPT a question. But this process is a one-way street, where ChatGPT answers your question and then stops. The new integration takes this approach a few steps further by letting you have a full conversation with the AI.

How the integration works

Assuming you meet all the criteria, start up your car and make sure your iPhone is connected. My Camry comes with wireless charging and synchronization, so I don’t have to plug it into a USB port as I did with my previous vehicle.

On your iPhone, go to Settings, select General, and tap CarPlay. Select your car and then tap Apps. You’ll see a list of all the apps compatible with CarPlay. Among those should be ChatGPT.

Using the three-lined hamburger icon, you can move the ChatGPT entry higher or lower in the list. I moved it higher so I could easily access it from the first CarPlay screen:

On the CarPlay screen, tap the ChatGPT icon and select “New voice chat.” Wait for the connection to kick in, as the text on the display changes from Connecting to Listening. You can then kick off your conversation, and ChatGPT will respond as it normally would:

From the main ChatGPT screen, you can see your previous chats. Tap a specific chat to resume it. If you’ve stored any past conversations in a dedicated project, you can also select that project to access the stored chats.

So far, so good. But what if you’re driving and need to keep your eyes on the road? All that tapping can be a dangerous distraction. 

Thankfully, you can set up ChatGPT to automatically start in voice mode. To do that, make sure ChatGPT is on the CarPlay screen. Open the ChatGPT app on your iPhone and go to Settings. In the Voice section, turn on the switch for “Start automatically in CarPlay.” The next time you open ChatGPT in CarPlay, voice mode should be on by default.

OK, but you still have to navigate to and tap the ChatGPT app in CarPlay to open it. Ahh, but not if you turn to Siri. Just say: “Siri, open ChatGPT.” From there, ChatGPT should then launch in voice mode, ready for you to start the conversation.

This integration all sounds promising. Yes, but there are limitations.

Unlike Siri, ChatGPT can’t directly work with your iPhone. The AI doesn’t have access to email, messaging, Maps, or any of your other apps. Nor can ChatGPT see your live location. That limitation means you still have to rely on Siri to send an email or text, check your calendar, listen to music, get directions, and more. Instead, think of ChatGPT as a way to provide information and handle requests that would normally stump Siri.

Plus, there are other ways ChatGPT can help you in the car. Maybe you face a long daily commute to work or you’re driving on a long trip all by yourself. Why not strike up a conversation with the AI to pass the time? Beyond just asking it challenging questions, you can simply chit chat about whatever’s on your mind. You can even use ChatGPT for entertainment. Ask it to tell you a story, play a game with you, or teach you a new language.

How does ChatGPT fare with CarPlay? 

I aimed several questions and requests at the AI to test it. My questions were all answered. The conversations ran smoothly and naturally. The voice was clear and responsive. The only hiccup was in starting ChatGPT. Though I turned on the switch to always launch in voice mode, ChatGPT sometimes failed to start up that way, forcing me to tap the screen to kick off a conversation.

Otherwise, this integration is a helpful and effective way to use ChatGPT in the car. I’ll certainly be turning to this approach the next time I’m driving and want to strike up a conversation with my favorite AI.
