Android Auto Calls Not Working

Android Auto calls not working often comes from Bluetooth call routing, blocked mic access, or a stuck dialer link, and simple checks fix it.

When calls fail inside Android Auto, it can feel random. Maps and music work, the screen shows the call, then you get silence, a dead mic, or the audio stays on your phone. Most call issues come from the same small set of settings, so a checklist beats guessing. It’s maddening sometimes.

Do the steps while parked. If your head unit sleeps fast, keep the car on for testing. Once calls work again, stop right there.

Android Auto Calls Not Working In Your Car

Start with fixes that take less than two minutes. These steps solve the common “it worked yesterday” call failures.

Restart The Whole Chain — Reboot your phone, then restart the car’s head unit. If your car has no restart button, turn the car off, open the driver door, wait a moment, then start again.
Reconnect With A Clean Plug — Unplug the USB cable, wait five seconds, then plug it back in. If you use wireless Android Auto, toggle Bluetooth off and on, then reconnect.
Turn Up Call Volume While A Call Is Live — Place a test call and raise the volume using the car knob. Many cars store a separate call volume that doesn’t follow media volume.
Pick The Right Audio Output — During the call, tap the audio output button on your phone’s call screen and select your car or Bluetooth. If it’s stuck on “Phone,” the call will stay on the handset.
Confirm Bluetooth Is Still Paired — Android Auto can appear on screen even when the Bluetooth profile for calls dropped. Open Bluetooth settings and make sure your car is connected.

If you still see android auto calls not working, match the symptom first so you don’t chase the wrong fix.

Match Your Symptom To The Fix

Call problems show up in repeat patterns. Use this table to pick the shortest path, then follow the deeper steps in the next sections.

Symptom	Likely Cause	Try This First
Call connects but there’s no sound	Bluetooth call audio off or routed to phone	Enable “Phone calls” for the car in Bluetooth settings, then place a new test call
You can hear them, they can’t hear you	Mic permission blocked or car mic not selected	Allow Microphone for Android Auto and the Google app, then try again
Dialing spins, then fails	Phone app link is stuck or call permission is missing	Set your default Phone app, then force stop Android Auto and reopen
Calls work on Bluetooth, not on Android Auto	Android Auto app data is corrupted	Clear Android Auto cache and storage, then set up the car again
Works only after you unplug and replug	USB handshake issue or adapter glitch	Try a different cable or port, or test without the wireless adapter

The next section targets Bluetooth call routing, because Android Auto relies on it for phone-call audio even when everything else runs over USB or Wi-Fi.

Fix Bluetooth Call Audio And Routing

Android Auto can be connected and still fail at calls if the Bluetooth “phone” profile is off, unstable, or competing with another device. This is common if earbuds reconnect in the driveway or a watch grabs the call audio first.

Check The Bluetooth Toggles That Control Calls

Open Bluetooth Device Details — On your phone, go to Settings, open Bluetooth, tap the gear icon next to your car, then review the available toggles.
Enable Phone Calls — Turn on the “Phone calls” or “Calls” switch for your car. If it’s off, Android Auto can still show maps and media, but calls won’t route to the car.
Disconnect Other Audio Devices — Temporarily disconnect earbuds, speakers, or a second car kit. Then retest calls with only the car connected.

Re-Pair The Car The Right Way

If the toggles look correct but audio still refuses to route, rebuild the pairing so your phone and head unit agree on call roles.

Forget The Car On Your Phone — In Bluetooth settings, remove the car from your paired list.
Delete The Phone On The Car — In the head unit’s Bluetooth menu, remove your phone from saved devices.
Restart Both Devices — Reboot the phone and restart the head unit so stale sessions drop.
Pair Bluetooth First — Pair the phone and car using the normal Bluetooth flow, then confirm you can place a call over plain Bluetooth.
Set Up Android Auto Again — Plug in the USB cable or start the wireless pairing, then accept every prompt for calls and contacts.

Spot A Routing Problem During A Live Call

Sometimes the link is fine and the call still lands in the wrong place. Catch it while the call is active.

Switch Audio Output — On the phone call screen, tap the audio route button and choose Bluetooth or your car.
Toggle Speaker And Bluetooth — Flip to speaker, wait one second, then flip back to Bluetooth to kick the route back to the car.
Hang Up And Redial — End the call and place a fresh test call. Many routing bugs clear only on a new call session.

If you can hear calls again but your voice still doesn’t reach the other end, the next section is for microphone and permission issues.

Fix Microphone, Voice, And Call Controls

A dead mic inside Android Auto is often tied to blocked microphone access, a privacy toggle, or the car using a different mic than you expect.

Grant The Right Microphone Permissions

Allow Microphone For Android Auto — Open Settings, go to Apps, find Android Auto, open Permissions, then set Microphone to Allow while in use.
Allow Microphone For The Google App — Many voice and call actions go through the Google app. Give it Microphone permission as well.
Check The System Mic Toggle — If your phone has a privacy mic switch in Quick Settings, make sure it’s on. If it’s off, Android Auto can’t hear you.

Make Sure The Car Mic Is The Active Input

Start A Test Call — Call voicemail or a friend who can test quickly.
Select Bluetooth As Input — On some phones, the same audio route button controls both speaker and mic path. Choose the car or Bluetooth option.
Check For Phone Mic Grab — If the other person hears you only when you hold the phone, the call is routing through the handset. Switch back to the car route and test again.

Fix Call Buttons That Don’t Respond

If the screen shows the call but the answer, hang up, or dial pad buttons don’t work, the phone app link may be stuck.

Set A Default Phone App — In Settings, choose your default Phone app and avoid switching dialers during testing.
Force Stop Android Auto — In Settings, open Apps, select Android Auto, tap Force stop, then reconnect to the car.
Update The Phone App — Open the Play Store and update the Phone app and Android Auto so they stay compatible.

If calls broke right after a system update or an Android Auto update, reset app data and connection profiles next.

Phone Calls Not Routing After Updates Or Changes

Updates can flip permissions, reset Bluetooth roles, or leave old data behind. If android auto calls not working started right after an update, run these steps in order so you don’t wipe settings you didn’t need to touch.

Refresh Android Auto With Minimal Disruption

Update Android Auto And Google — In the Play Store, update Android Auto, Google, and Google Play services if updates are available.
Clear Cache First — In Settings, open Apps, select Android Auto, tap Storage, then tap Clear cache. Test calls before doing anything heavier.
Clear Storage If Needed — If cache doesn’t help, tap Clear storage, then set up Android Auto again. This resets car entries, so expect prompts.

Reset The Connection Profiles

Remove The Car From Android Auto — In Android Auto settings, remove your connected car profile so setup starts fresh.
Reset Network Settings — If Bluetooth won’t stay stable, use the phone’s Reset options to reset Wi-Fi, mobile, and Bluetooth settings, then re-pair the car.
Allow Background Running — In battery settings, set Android Auto to Unrestricted so it can keep the call link alive while the screen is off.

Check Car Firmware And Phone Updates

Some call failures are fixed by a head unit firmware patch, not by a phone tweak. If your car has an update menu, check it while parked. If it’s an aftermarket receiver, check the maker’s site for a firmware file that mentions hands-free or Bluetooth fixes.

If Android Auto calls not working still shows up after the reset steps, separate an Android Auto issue from a hands-free issue with two quick tests.

Run Two Quick Tests To Pinpoint The Cause

You just need two controlled tests that remove one variable at a time.

Test Plain Bluetooth Without Android Auto

Disconnect Android Auto — Unplug the cable or turn off wireless Android Auto for the moment.
Connect Bluetooth Only — Pair the phone to the car and place a call using the car’s dialer.
Note The Result — If Bluetooth-only calls fail, the problem is the hands-free link or car settings. If Bluetooth-only calls work, Android Auto settings or app data are the more likely cause.

Test Wired Vs Wireless

Try A Known-Good Cable — Use a short data-capable cable and plug into the main USB port for Android Auto.
Try Without Adapters — If you use a wireless adapter, remove it for the test. Adapters can add their own Bluetooth or Wi-Fi issues.
Compare Results — If wired works and wireless fails, start with Bluetooth stability and adapter firmware.

Once you know which path fails, stop changing random settings. Stick with the failing path and apply only fixes tied to that path.

Keep It Stable Once Calls Work Again

After you get calls back, a few habits prevent repeat glitches.

Limit Auto-Connecting Devices — Set earbuds and speakers to manual connect so they don’t steal call audio when you start the car.
Use One Primary Pairing — Avoid pairing the same phone to the car under multiple profiles unless the head unit requires it.
Keep Apps Updated — Update Android Auto and Google apps regularly, since call bugs are fixed in small releases.
Reboot When It Acts Up — A phone reboot clears stuck call routes faster than chasing toggles while parked.

If you work through the steps in order, you’ll almost always find the one break in the chain: Bluetooth call audio, mic access, or a stale Android Auto profile. Fix that one piece, and calls behave again.
