Your Subaru should put maps, music, calls, and messages on the dash without repeated plugging, tapping, or restarting.
When Apple CarPlay will not launch, keeps dropping, or shows Bluetooth connected but no CarPlay screen, work through the official Apple and Subaru fixes in the order below.
Start with compatibility and the physical connection, then move into iPhone settings, pairing, software, and network resets.
1. Verify your Subaru supports CarPlay
Open Apple’s CarPlay available-models page and find Subaru.
Match your exact model year against Apple’s current Subaru list: 2017-2025 Impreza; 2018-2025 BRZ, Crosstrek, Legacy, and Outback; 2019-2025 Ascent, Forester, and WRX; 2019-2022 WRX STI; 2023-2025 Solterra; 2026 Trailseeker; and 2026 Uncharted.
Check Subaru owner resources for your trim and installed infotainment system because CarPlay availability can vary by country, trim, and package.
2. Fix the USB connection first
Use the Subaru USB port marked with the CarPlay icon or smartphone icon.
Then plug the iPhone directly into that USB port instead of using adapter chains.
Try a different USB cable, preferably a quality USB-IF or MFi cable.
After that, move the cable to another Subaru USB port if the vehicle has more than one.
Unlock the iPhone, disconnect the cable, then reconnect it while the phone is unlocked.
For stubborn wired failures, open Settings > Privacy & Security > Wired Accessories and choose Automatically Allow When Unlocked or Always Allow.
3. Turn on the wireless basics
This fixes wireless CarPlay that never appears, will not auto-join, or drops before the Subaru screen opens CarPlay.
On iPhone, open Settings > Bluetooth and turn Bluetooth on.
Next, open Settings > Wi-Fi and turn Wi-Fi on.
Tap the CarPlay network and turn on Auto-Join.
On the Subaru display, select the Apple CarPlay or CarPlay app if it does not open automatically.
4. Allow CarPlay on the iPhone
CarPlay requires Siri, so open Settings > Apple Intelligence & Siri or Siri > Talk & Type to Siri or Talk to Siri, then turn on Siri activation.
If Screen Time is blocking CarPlay, go to Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps & Features (still labeled Allowed Apps on older iOS versions) and enable CarPlay.
For a saved Subaru profile, open Settings > General > CarPlay > your Subaru and turn on Allow CarPlay While Locked.
5. Pair wireless CarPlay again
This fixes a first-time setup that stalled, a replacement iPhone that never paired cleanly, or a Subaru that connects by Bluetooth but does not launch CarPlay.
- 1.For Subaru’s USB setup flow, plug the iPhone into one of the front USB-A or USB-C ports.
- 2.On iPhone, select ENABLE WIRELESS CARPLAY.
- 3.On the Subaru Apple CarPlay popup, select YES.
- 4.On Device Registration, select YES to make the iPhone the favorite device.
- 5.For Subaru’s Bluetooth setup flow, open the vehicle phone or device pairing screen, add a phone or device, select the Subaru Bluetooth device on iPhone, confirm the pairing prompts, then choose Set on Device Registration to make the iPhone the favorite device.
- 6.If CarPlay still does not appear, press HOME on the Subaru display and select CarPlay or Apple CarPlay.
6. Restart the phone and Subaru screen
Restart the iPhone first: for iPhone X or later, hold either Volume button and the Side Button until the power-off slider appears, drag the slider, wait 30 seconds, then hold the Side Button until the Apple logo appears.
Turn the Subaru off and back on because Subaru recommends restarting the car after pairing to complete syncing.
If the Subaru touchscreen or infotainment system is unresponsive, use the owner-manual reset for your head unit; on supported 11.6-inch display systems, press and hold the physical volume/power knob for 10 seconds or longer.
7. Forget the Subaru and start over
On iPhone, open Settings > Bluetooth, tap the blue i next to your Subaru, then tap Forget This Device.
Go to Settings > General > CarPlay, select your Subaru, then tap Forget This Car.
On the Subaru touchscreen, select Manage Devices.
Select Delete, then select your iPhone to remove it from the vehicle.
Pair again through Subaru’s Bluetooth setup flow, or plug the iPhone into USB to try Subaru’s USB-initiated wireless setup.
Use this reset after a bad pairing, an iPhone replacement, an iOS update, or repeated wireless handoff failures.
8. Update software and broken apps
On iPhone, open Settings > General > Software Update, then tap Download and Install if an iOS update is available.
For the Subaru multimedia software itself, connect the vehicle to Wi-Fi on the touchscreen, then open Settings > General > Check for Updates, select Download Now, and select Install Now when the download finishes. Use Subaru’s Vehicle Navigation Map Updates page for on-board map packages only, selecting the vehicle Year, Model, and Trim; select 2023-and-later models use cloud navigation and do not need map updates.
When only one CarPlay app fails, open App Store, tap your account button or photo, tap App Updates, then tap Update beside that app or Update All.
To restore a missing CarPlay app, open Settings > General > CarPlay > your Subaru > Customize, then use the add, delete, and drag controls.
If one third-party app still fails while the rest of CarPlay works, delete it from iPhone, reinstall it from the App Store, then use App Support on the app’s App Store page.
9. Save network resets for last
This fixes persistent wireless CarPlay pairing or Wi-Fi handoff failures after the cable, pairing, Siri, Screen Time, and app checks are done.
If VPN or security software is installed and wireless CarPlay keeps failing, uninstall the software.
Restart the iPhone, then test CarPlay again.
If the software is required, contact the VPN manager or security software provider.
As a last resort, open Settings > General > Transfer or Reset [device] > Reset > Reset Network Settings.
Expect this to remove saved Wi-Fi networks and passwords, cellular settings, and VPN or APN settings.
For a work or school iPhone, contact your organization before removing profiles, uninstalling required security software, or resetting network settings.
Skip older Subaru forum fixes that depend on changing location permissions for the old Subaru STARLINK mobile app.
The current Subaru support paths route owners to Apple CarPlay setup, MySubaru Connected Services, and Subaru infotainment or map updates.
Frequently Asked Questions
Why does Subaru CarPlay work only after I unlock my iPhone?
Turn on Allow CarPlay While Locked under Settings > General > CarPlay > your Subaru. For wired CarPlay, unlock the iPhone before reconnecting the USB cable, then use the Wired Accessories setting if the phone still blocks the connection.
Why is my Subaru connected by Bluetooth but CarPlay is not showing?
Wireless CarPlay also needs Wi-Fi. Turn on Bluetooth and Wi-Fi, enable Auto-Join for the CarPlay network, then open the CarPlay or Apple CarPlay app from the Subaru Home screen if it does not launch automatically.
Can a bad cable stop Subaru Apple CarPlay from working?
Yes. Use the Subaru USB port marked for CarPlay or smartphone use, plug the iPhone in directly, and test with a quality USB-IF or MFi cable.
What should I do when only Spotify, Maps, or another CarPlay app fails?
Update that app from the App Store. If the rest of CarPlay works and the app still fails, delete and reinstall the app, then contact the developer through App Support on the App Store page.
