CarPlay app not receiving data updates when iPhone screen is locked
We are building a CarPlay app and have run into an issue with data updates. When the app is running on the CarPlay display and the iPhone screen is locked, no data updates are shown on the CarPlay screen. As soon as the phone is unlocked, the data updates appear instantly on the CarPlay display. Has anyone encountered this behavior before? Is there a specific setting, entitlement, or background mode we need to enable in order to ensure the CarPlay app continues to receive and display data while the iPhone is locked? Any guidance would be greatly appreciated.

Old values not cleared when Live Activity updates in CarPlay
I'm updating some of the views for a Live Activity, now that CarPlay can display Live Activities in iOS 26. My Activity is updated only with local updates from the iPhone (no push notifications), displaying a user's blood glucose. The activity updates fine in both CarPlay and in the Apple Watch Smart Stack, but in CarPlay, the previous values are not cleared when the new values are displayed, resulting in superimposed text and making it essentially unreadable. This only happens when the iPhone screen is off. As soon as the phone screen is woken up, even if the phone is not unlocked, the old values disappear and the display looks fine. I can't find anything in the API about clearing a display, so I'm wondering if this is a bug (especially since it clears when waking the phone screen). I'm running iOS 26.0.1 on my test phone. Thanks for any thoughts!

Using HealthKit to display data on CarPlay UI
I'd like to investigate creating a safety feature for Type 1 Diabetics driving a car. Allowing HealthKit glucose data (read from a Dexcom G7 or similar) to be displayed as part of the CarPlay UI background or show an icon/button with the number visible. I'd also like to include a warning system for glucose low's that alerts the driver audibly. Has anyone looked into that before?

[CarPlay] CPNowPlayingTemplate not being accepted when being passed to pushTemplate:animated:completion
Hey team, I have an app in CarPlay where i was pushing the CPNowPlayingTemplate as follows: self.interfaceController.pushTemplate(CPNowPlayingTemplate.shared(), animated: true) This used to work perfectly, but suddenly I have started to get this error NSInvalidArgumentException: Unsupported object <CPNowPlayingTemplate: 0x119a0b5c0> <identifier: 6EE4E5A9-B1FB-4341-A485-78D7DDEBD8D0, userInfo: (null), tabTitle: (null), tabImage: (null), showsTabBadge: 0> passed to pushTemplate:animated:completion:. Allowed classes: {( CPActionSheetTemplate, CPAlertTemplate, CPVoiceControlTemplate, CPTabBarTemplate, CPListTemplate, CPInformationTemplate, CPContactTemplate, CPMapTemplate, CPGridTemplate, CPSearchTemplate )} How is this possible? Even on Apple docs, it says to pushTemplate Refer https://developer.apple.com/download/files/CarPlay-Developer-Guide.pdf https://developer.apple.com/documentation/carplay/cpnowplayingtemplate/

ios 26 beta: Podcast chapter images not updating on Carplay or USB/Bluetooth
With ios 26 the chapter images are not updating anymore. At first I thought this is carlay related but it also occures when the phone is connected only through USB or bluetooth to play a podcast. I tried Apple podcasts and other apps like Pocketcast or audible. Same problem. The phone shows the correct chapter image while my car shows the inital image all the time. Even tried a different car :-) I checked focus and settings but found nothing related. With ios18 everything works fine. Any ideas?

Cluster not displaying in CarPlay POI template on iPhone 14 with iOS 26.0.1
I am experiencing an issue with the CarPlay POI template in my CarPlay application. On my iPhone 14 running iOS 26.0.1, the clustering of POIs on the CarPlay map is not displaying at all. However, this issue only affects this specific model and OS version. The same app works correctly on an iPhone 14 with iOS 18.5 and on an iPhone 16 Pro Max with iOS 26.0.1. There are no code changes between builds for each device.

CarPlay Image Issue on iPhone 17?
Has anyone else had any issued with their CarPlay with the new phone? My screen gets distorted and you cannot make up anything that shows up on it, it's specific to the new phone since I have also tried it with an iPhone 15 Pro and iPhone 13. I have updated my car's firmware, reset it, reset my phone settings (per Apple's request) and nothing seems to be working, and unfortunately since I'm on the beta they are limited with the assistance they are able to provide to me.

CarPlay Simulator: How to Change Dock Position for Right-Hand Drive (RHD)
Hello everyone, I'm developing a CarPlay app and am trying to test it with the dock on the right side of the screen, as is standard for right-hand drive vehicles like those in Japan. Currently, the CarPlay Simulator always displays the dock on the left, and I can't find an option to change its position. This is important for ensuring a proper user experience for my target market. Has anyone figured out how to configure the simulator for RHD layouts? Any guidance on how to move the dock to the right would be greatly appreciated. Thanks in advance for your help!

CarPlay Driving Task notification press handling
We're trying to add simple notifications to our CarPlay integration that should open certain template when pressed, but the issue is that when pressing this notification on CarPlay screen nothing is invoked in the code (presumably didReceive should be invoked). All works fine with the same notification but pressed on the iPhone screen - didReceive is invoked properly. How should I handle the action when push notification is pressed on CarPlay screen?

CarPlay not working on Apple iPhone 15 PRO MAX iOS 26
I have a FORD F250 2021. I returned for a deployment, and CarPlay does not work in my vehicle. I have tried all the YouTube, TikTok, Facebook, and Instagram videos I could find. They all actually started to repeat, so I decided to come here. My wife has an iPhone 16 Pro Max, and it connects to CarPlay without any issues. Other than all the social media suggestions, do you have any other suggestions? No, I am not ready to purchase a new device.

Seeking Guidance: Car Play App Rejected.
Hello Apple Community, I'm seeking guidance on a Car Play app rejection from the apple team. My mobile-only app was approved, but the version that includes the Car play app is consistently being rejected, and I'm trying to understand the reasons for the same. I'm hoping to get insights from developers who have successfully published Car Play apps, especially those involving voice interaction. About the App My ios app is an AI-powered voice agent for drivers, designed to provide a hands-free, conversational experience. The app's features include: Information & Navigation Live weather updates. Turn-by-turn navigation for single or multiple destinations, which opens Google Maps. Real-time data lookups (flight status, stock prices, news, sports scores). Media & Entertainment Playing songs via Spotify and YouTube Music. Productivity Setting time-based reminders. Making phone calls. Vehicle Integration Remote commands for the vehicle (e.g., "lock the doors," "open the trunk"). Accessing vehicle data (fuel level, tire pressure, etc.). The Problem: Car Play Rejection When I remove the Car Play code and manifest declaration, the app gets approved for mobile. However, as soon as I include the Car Play implementation, the app update is rejected. This leads me to believe the issue is not with the app's core functionality but specifically with how it presents itself on Car Play. My Core Question for the Community Is the rejection likely because Car Play does not permit third-party, general-purpose voice assistants as a primary app interface? The platform seems to reserve core voice control for the integrated Siri and third-party apps are expected to fit into specific categories (Media, Navigation, IoT, etc.) using the Car App Library templates. My app acts as a single, all-in-one assistant, which is not one of the listed categories. What is the correct path to bring my app's features to Car Play? Is it against policy to have a custom voice assistant, even if its capabilities fall into supported functions like navigation and media? Should I fundamentally change my approach? For example, should I break the app down and submit it as a Navigation or IoT app that uses the official Car App Library templates, and then offer my voice capabilities within that compliant structure? Has anyone successfully integrated a third-party voice service into a Car play app, and what was the approved architecture? Or any other path you suggest based on your experience. I've reviewed the "Car app quality" guidelines but am looking for practical interpretation and advice from those with experience. Any insights you can share would be incredibly helpful. Thank you

iOS 26 Beta 9 dark/light behaviour over custom UIViews in UITabBarController and CPMapTemplate
I have an app where the user can choose if the dark / light mode is enabled automatically during the night / day (dusk and dawn times are calculated according to to the date and location of the user). I also have an UITabBarController, with two tabs which have a GMSMapView (Google Map View from their SDK), and three tabs with UITableViews. I have noticed that when the automatic change of dark / light mode is performed from dark to light mode, and the user is in a tab with GMSMapView, the tabBar does not change to light model, it remains in dark mode. I perform the switch by setting the self.window.overrideUserInterfaceStyle of the UIWindow of the UIScene. All the views change to light mode, including the navigation bar, but not the tab bar. If I move between the tabs with GMSMapView, the tabBar stays in dark mode. As soon as I move to a tab which contains a UITableView, the tabBar switches to light mode. If the switch to light mode is performed while the user is in tab with the UITableViews, the tabBar switches to light mode immediately, as expected. When moving to the tabs with the GMSMapViews, the tabBar stays in light mode, also as expected. I have also noticed the same problem in CarPlay, in CPMapTemplate (with a UIViewController whose view is GMSMapView), in the buttons with are set with the property “mapButtons”, and with the panning buttons. When the switch from dark mode to light mode is performed by setting the self.window.overrideUserInterfaceStyle of the UIWindow of CarPlay scene, the mapButtons keeps the glyphs in white, and set the background of the buttons to almost white, so the glyphs are barely visible unless you put png images on them instead of SF Symbols. With the panning buttons there is not workaround, since you cannot set custom images for the panning buttons. This happens even if the panning buttons are not being displayed when the switch is performed to light mode, and you enable them later. Is this a bug? Why does this only happen with view over GMSMapView (Google Maps view for a map from their SDK)? Can you think of any viable workaround? Thank you.

CarPlay Still not Functioning
I have a Nissan Rogue 2021 and iPhone 14 Pro Max. Carplay was working fine until I decided to update to the new beta program and now my carplay does not seem to want to operate at all. I do the fixes online suggest in rebooting both systems, forgetting entirely and reconnecting. In the process of doing so, I can get the prompts to start with "Allow while unlocked?" But once selecting that I am unable to actually use the Carplay from the phone. It doesn't even give option to switch to it when I attempt to change audio output. Since June. Starting another post in hopes something can be done.

Play Audio and Recognize Speech in Car
Hello, I'm trying to determine the best/recommended AVAudioSession configuration (i.e category, mode, and options) for the following use-case. Essentially, I'd like to switch between periods of playing an audio file and then recognizing speech. The audio file is typically speech and I don't intend for playback and speech recognition to occur simultaneously. I'd like for the user to sill be able to interact with Siri and I'd like for it to work with CarPlay where navigation prompts can occur. I would assume the category to use is 'playAndRecord', but I'm not sure if it's better to just set that once for the entire lifecycle, or set to 'playback' for audio file playback and then switch to 'playAndRecord' for speech recognition . I'm also not sure on the best 'mode' and 'options' to set. Any suggestions would be appreciated. Thanks.

iOS 26 PB5 CarPlay possibly crashing car's infotainment system
This is purely speculation (but I have reason to believe it is the case) because I'm trying to narrow it down but, has anyone reported CarPlay in iOS 26 Beta potentially crashing vehicle infotainment systems? I have a 2025 Jeep Wrangler which is running UConnect 5. I can't prove it is the case but since updating to IOS 26 PB, I've been noticing that my infotainment system in my vehicle has been freezing, locking up, and resetting upon boot. I can't narrow this down to the phone causing it, but I can't rule it out as of now. I know that most of our infotainment units that offer CarPlay are typically running off Android, but is there a possibility that the iOS Beta is crashing our infotainment units upon connection? Again, I am just posting this to see if a) anyone can confirm that yes CarPlay can crash the Android backend of infotainment units or b) if anyone has experienced odd issues with CarPlay and their vehicle's infotainment system either freezing, crashing, or rebooting since installing iOS Beta 26. It happens when the iPhone is connected wirelessly via CarPlay, and I believe also when it is connected wired via CarPlay.

Wrong tint on CPMapButton in iOS 26
In my CarPlay app my CPMapButton with system images have the wrong tint when the CarPlay appearance is set to "Always Dark". Here is what it looks like. When I change the system appearance to "Automatic" the buttons look fine. Has anyone encountered this or know how to fix it?
