Most Subaru Android Auto failures come from a bad data cable, a blocked permission, or a stuck head unit, and you can fix those with a few focused checks.
Your Subaru should feel like plug-and-play. Then one day it doesn’t. The screen shows “No device,” Android Auto launches and quits, or audio drops mid-drive. If you searched android auto not working subaru, you’re not alone, and you don’t need to guess.
This guide walks the connection from the USB port to your phone settings, so you can stop swapping random toggles and get back to a stable link.
Why Android Auto Stops Working In Subaru
Android Auto has to charge your phone, pass data, keep calls available, and maintain a steady handshake with your car display. One weak link can make it look like nothing works.
Subaru adds another wrinkle: many models route projection through a specific USB data port. A port that only charges, a loose connector, or a worn socket can make the car miss the connection even while your phone charges.
Updates can also shift behavior. A phone update or an Android Auto update can change permissions, background limits, or wireless pairing. That doesn’t mean your Subaru “broke.” It means the stack needs a clean re-seat.
Before you chase settings, check two basics: your phone needs Android 9 or newer for Android Auto on the car display, and the car has to be on the Android Auto compatible list. If you recently moved from an older phone, that alone can explain why the same cable suddenly stopped working.
Clues That Point To The Cause
- Charges but won’t launch — The cable may be power-only, or the data pins aren’t making clean contact.
- Launches then drops — A marginal cable, a loose port, or a head unit that needs a reboot can cause this.
- Works in other cars — Your phone setup is fine; focus on the Subaru port and infotainment settings.
Android Auto Not Working Subaru Checks Before You Dig Deeper
Start here. These checks catch the most common failures and take only a few minutes. Do them in order so you can tell which change helped.
- Try a different data cable — Use a short, high-quality cable, under about 1 meter, with no hubs or extensions.
- Flip the USB end — If your Subaru uses USB-A, rotate the connector once; worn plugs can make better contact on one side.
- Clean the phone port — Pocket lint can stop the plug from seating. Power off, then gently clear debris with a non-metal pick.
- Use the correct Subaru USB port — Many Subarus have one data port and one charge-only port; use the one meant for phone projection.
- Reboot the phone — A restart clears stuck USB and Bluetooth services.
- Reboot the Subaru head unit — With the car in Park, hold the power/volume knob until the screen restarts, then reconnect.
Fixing Android Auto Not Working On Subaru Vehicles With USB Steps
If the quick checks didn’t help, treat USB like a system: cable, port, and handshake. Google notes that swapping the USB cable is often the fix when Android Auto used to work and then stopped.
Pick A Cable That Can Carry Stable Data
Many USB-C cables are built for charging first. They’ll power the phone but won’t carry steady data at the rate Android Auto wants. Use the cable that came with your phone or a USB-IF certified cable, and keep it short.
| What You See | Most Likely Cause | Fastest Check |
|---|---|---|
| Phone charges, car says “No device” | Power-only cable or weak data pins | Swap to a short known-good cable |
| Android Auto starts, then drops | Loose USB port or cable wiggle | Hold the plug steady and test again |
| Works once, fails next drive | Head unit session stuck | Reboot the head unit, then reconnect |
Check The Subaru Side Of The USB Path
- Inspect the port feel — If the plug wobbles, the port may be worn, and small bumps can drop the link.
- Remove splitters and adapters — USB hubs and extensions can reduce reliability.
- Try another phone — If a second Android phone works in the same port with the same cable, the fix is on your phone.
- Try another USB port — Some Subaru trims offer more than one port; only one may be the data port.
Fixes Inside Android Settings That Block Android Auto
Android Auto can fail even with perfect hardware if Android blocks permissions or background activity. A privacy change, a work profile, or a new phone can also break the first-time handshake.
Reset Android Auto’s Car List
When you connect to more than one vehicle, old entries can trip pairing. Google’s Help Center recommends forgetting cars and trying again when connection gets stuck.
- Unplug from the Subaru — Leave the cable out while you change settings.
- Open Android Auto settings — On many phones it’s under Settings, then Connected devices, then Connection preferences, then Android Auto.
- Forget paired cars — Remove old entries, then reconnect and accept the prompts.
Check The Permissions That Matter
For full features, Android Auto needs access to calls, contacts, location, and notifications. If any are blocked, the car can show a blank interface, fail to load apps, or refuse voice actions.
- Allow phone and contacts — Turn on call and contact access so calls and caller ID work.
- Allow location — Set location access to allow while using, and confirm Location is turned on.
- Allow notifications — Turn on notification access so message apps can appear.
- Allow background activity — Set Android Auto and Google Play services to unrestricted battery use if your phone offers that option.
Clear Android Auto Data When It Keeps Forgetting Your Subaru
If the car prompt keeps looping, or Android Auto keeps acting like it’s the first time, clear the stored data so the setup can start fresh. This does remove your saved cars, so plan to re-approve permissions on the next connect.
- Open App info — Go to Settings, then Apps, then find Android Auto.
- Clear cache — Tap Storage, then clear cache first and try a reconnect.
- Clear storage — If cache didn’t help, clear storage, then restart the phone.
- Reconnect and accept prompts — Plug into the Subaru data port, then tap Agree and allow each permission request.
Update The Apps Android Auto Relies On
Android Auto runs alongside Google Play services, Maps, and your media apps. Subaru also notes that keeping Android Auto and related apps up to date helps avoid launch issues.
- Update Android Auto — If your phone lists it in the Play Store, install updates.
- Update Google Play services — Check its Play Store page for pending updates.
- Update Maps and your audio app — A stuck update can make the dashboard act frozen.
Subaru Head Unit Fixes That Solve Sudden Breaks
If Android Auto is still flaky, treat the Subaru screen like a computer. It can get stuck after repeated connect and drop cycles. A restart and re-pair can clear the session.
Reboot, Then Re-Pair Cleanly
- Delete the phone from the Subaru — Remove your phone from the car’s Bluetooth list and any projection list you see.
- Delete the Subaru from the phone — Remove the car from Bluetooth devices, then restart the phone.
- Restart the head unit — Hold the power/volume knob until the screen restarts.
- Pair Bluetooth first — Subaru’s flow starts in the car’s Phone page with Add Device, then pairing on your phone.
- Plug in USB after pairing — Connect to the Subaru USB data port, then tap Agree on prompts.
Make Sure Android Auto Is Enabled On The Car
Google’s troubleshooting list includes checking that Android Auto is turned on in the infotainment system. If it’s off, the car won’t request projection even when the phone is ready.
- Open Subaru settings — Look for smartphone integration or phone projection options.
- Enable Android Auto — Turn it on, then reconnect.
- Set your phone as primary — If several phones are saved, choose the one the car should connect first.
Check For A Subaru Infotainment Update
Some head units can update through settings, while others need a dealer update. If the screen crashes, reboots, or forgets devices often, ask a Subaru retailer to check for the latest infotainment software and any open recalls for your VIN.
Wireless Android Auto In Subaru Troubleshooting
Wireless Android Auto adds Wi-Fi to the mix. Google lists wireless projection compatibility by Android version: many phones need Android 11, while certain Google and Samsung phones can use Android 10.
Test wired first. If wired is solid, your cable and permissions are fine, and the issue is usually wireless pairing or a recent Android Auto update.
- Forget the car on the phone — Remove the Subaru from Android Auto’s car list and Bluetooth list, then set it up again.
- Toggle Wi-Fi and Bluetooth — Turn both off, wait ten seconds, then turn them back on.
- Turn off VPN and private DNS — Some network filters interfere with the Wi-Fi handshake used for projection.
- Start with one clean wired session — Connect by cable, confirm it works, then try wireless again.
Android Auto has had stretches where an update triggered wireless failures on some phones. When that hits, using a cable for a while can keep you driving without reconnect loops.
When It Still Won’t Connect
If you’ve tried cables, resets, and setup, don’t keep repeating the same moves. Switch to a clean test plan so you can pinpoint the weak link.
Run A Clean Two-Drive Test
- Drive one with a new cable — Don’t change settings mid-drive. Note when it fails and what the screen shows.
- Drive two with a different phone — Borrow an Android 11+ phone if you can, and use the same Subaru USB port.
- Compare results — If the second phone works, the fix is on your phone. If both fail, focus on the Subaru port or head unit.
Signs It’s Time For A Dealer Check
- USB port feels loose — Physical wear won’t be fixed by settings.
- Head unit restarts on its own — That can point to a hardware issue or a needed software patch.
- Only charging works on every cable — The port’s data path may be damaged.
Bring notes. Share your phone model, Android version, whether wired and wireless both fail, and which cable you used. Mention that you removed and re-added the device, rebooted the head unit, and tested a short data cable. That keeps the visit tight.
If you landed here after searching android auto not working subaru, you now have a step-by-step way to isolate cable, phone, and car. Once you find the weak link and fix it, Android Auto tends to stay stable.
