Use Android Auto’s Quit developer mode command. Open your phone’s Android Auto settings, tap the three-dot Menu, and choose Quit developer mode. This exits developer mode without using the separate Forget all cars command, which clears Android Auto’s remembered-car list and can require pairing again.
Do not treat every Android Auto reset as equivalent. Quitting developer mode changes the developer-mode state; forgetting all cars changes connection data. The safest order is to leave developer mode, test the existing connection, and troubleshoot the cable, wireless setup, phone permissions, or car infotainment system before deleting remembered cars.
The safe reset: quit developer mode
Android Auto has a documented exit action for developer mode. On the phone, go to Settings, search for Android Auto, open Android Auto settings, tap the top-right Menu, and select Quit developer mode. That is the connection-preserving operation described by Google for leaving Android Auto developer mode.
Quitting developer mode does not use Previously connected cars and does not select Forget all cars. Your remembered car therefore remains in Android Auto’s connection data. Google does not document a separate one-tap command that guarantees clearing every developer preference while preserving every pairing, so treat quitting developer mode as the supported reset or exit operation rather than promising a full preference wipe.

Prepare before changing anything
If Android Auto is currently connected and you are collecting diagnostic information, park safely before operating the phone. Keep the phone and the vehicle display connected while you inspect settings if doing so is safe and practical; disconnecting first can remove useful symptoms from your troubleshooting sequence.
- Use the phone while parked, not while driving.
- Note which developer option was changed and what behavior appeared afterward.
- Keep the car’s ignition and infotainment system in the state in which the problem occurs until you have recorded the symptom.
- Do not open Forget all cars merely because developer mode is enabled.
- If a vehicle-side menu offers to forget the phone, postpone it unless you accept a new pairing process.
Step-by-step: leave Android Auto developer mode
- Open Settings on the Android phone.
- Use the Settings search field and search for Android Auto.
- Open Android Auto settings from the search results.
- Tap Version, or Version and permission info on versions that use that label, to expand the version information.
- If developer settings are not enabled, tap Version and permission info ten times. When Android Auto displays Allow development settings?, tap OK. This step only exposes the developer menu; it does not forget a car.
- Tap the top-right Menu. Select Developer settings when you need to inspect or change an option.
- To exit, open that same top-right Menu and tap Quit developer mode.
- Reconnect Android Auto normally and test the same car. Do not select Forget all cars during this sequence if retaining the remembered connection is the priority.
Google’s documented wording is: “To exit developer mode for Android Auto on your phone: Go to Settings and then search ‘Android Auto’ and select Android Auto settings; Select Menu and tap Quit developer mode.” Menu names can vary slightly by Android release, but the Android Auto settings search path is the reliable starting point.
Finding the right menu when labels differ
Android manufacturers can place Android Auto under different Settings categories, and Google’s labels have changed between releases. Searching Settings for Android Auto avoids guessing whether it is under connected devices, apps, or connection preferences. Once Android Auto settings are open, look for the version information and the three-dot Menu rather than a general Android reset command.
The ten-tap action is only an enablement step. It reveals Allow development settings? and, after confirmation, makes Developer settings available from the Menu. It does not clear pairings, erase the phone, or reset the car. If developer mode was already enabled, do not tap repeatedly just to reach the exit command; open Menu directly and choose Quit developer mode.
What this reset does—and what it does not do
What quitting developer mode changes
The command exits Android Auto’s developer-mode state. It is appropriate when you enabled developer settings for diagnostics, changed an experimental option, or simply want to return to normal operation. After leaving the mode, the developer-only controls are no longer the mode you are working in. If you later need them again, you can repeat the ten-tap process in the version information area.
What quitting developer mode does not guarantee
Google’s help pages do not promise that this command restores every developer preference to its original value. If one particular option caused the fault, re-enter Developer settings only after testing the normal connection. Change that single option, record the result, and avoid changing several variables at once. This isolates whether the option is responsible without sacrificing the car pairing.

What remains separate
Android Auto’s remembered-car list is managed through the connection controls under Previously connected cars. Leaving developer mode is not the same operation as deleting that list. A car can therefore remain remembered even though developer mode has been exited.

Recovery options compared
| Action | Changes developer mode? | Changes remembered-car data? | Applies to | Is re-pairing normally required? | Use it when |
|---|---|---|---|---|---|
| Quit developer mode | Yes; exits the documented developer mode | No car-list deletion is specified | Android Auto settings on the phone; relevant to wired and wireless use | No, not solely because you quit the mode | You want to return to normal mode while retaining the car |
| Forget all cars | No; it is a connection-data action | Yes; removes Android Auto’s remembered-car list | Phone-side Android Auto connection history | Yes, pair each needed car again | A later recovery step when you accept rebuilding connections, especially for a second-car problem |
| Vehicle-side forget phone | No | It removes the vehicle’s stored phone connection; the exact menu is manufacturer-specific | The car’s infotainment system | Yes, pair the phone again | The vehicle manufacturer directs you to clear a corrupted phone entry |
| Change one developer option | Developer mode remains available | No | The specific Android Auto behavior controlled by that option | No | You have identified a single setting to test and want to preserve all pairing data |
The table’s distinction matters: only the first and fourth actions are designed to leave the remembered-car list alone. The two forget actions can be useful, but they are not connection-preserving resets.
Choose the least destructive action by symptom
- You only want developer controls gone: choose Quit developer mode. Nothing in Google’s documented procedure asks you to delete a car.
- The phone still connects, but projection does not start: check whether Android Auto is enabled on the car display and restart the infotainment system before changing connection records.
- A wired connection drops or never appears: check the USB data cable and the vehicle’s Android Auto-capable port.
- Wireless setup will not complete: keep Bluetooth, Wi-Fi, and Location Services enabled and repeat the normal pairing flow.
- Only one vehicle fails: investigate that vehicle’s compatibility, firmware, port, or stored phone entry.
- Several vehicles are confused or a second-car connection is the problem: consider Forget all cars only when you accept pairing every needed vehicle again.
This order separates a mode change from connection-data deletion. It also gives you a clear result after each action, making it easier to tell whether the phone, cable, wireless setup, or car system is responsible.
If Android Auto still fails after quitting developer mode
Work through the least destructive checks first. The symptom and connection type determine the next step.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Scan for outdated or missing drivers - takes under a minute3Clear out junk files and repair common Windows errorsFor a wired connection
- Inspect the USB cable for damage, loose connectors, or a charge-only design.
- Try a known-good USB data cable that supports phone-to-car data transfer. A cable that charges the phone can still fail to carry Android Auto data.
- Connect directly to the vehicle’s Android Auto-capable USB port rather than a passive hub or adapter.
- Restart the car’s infotainment system and then reconnect the phone.
- If the same cable works with another compatible vehicle or data device but not this car, suspect the car port, infotainment software, or vehicle compatibility rather than developer mode.
Google’s Android Auto troubleshooting guidance specifically recommends checking the USB cable and restarting the car infotainment system. Replacing a cable addresses a wired data path; it cannot repair a wireless pairing record or update vehicle firmware. A USB-C data cable for Android Auto can be a sensible replacement for wired users, but the appropriate connector and cable capability depend on the phone and vehicle. No cable replacement is relevant to a wireless-only fault.

For a wireless connection
Wireless Android Auto setup depends on more than Bluetooth alone. Keep Bluetooth, Wi-Fi, and Location Services enabled while the phone and car are pairing. Google explains that wireless Android Auto begins after the phone and car pair over Bluetooth, while the wireless connection also relies on the other radios and location availability during setup.
- Turn on Bluetooth, Wi-Fi, and Location Services on the phone.
- Place the phone near the car and start the vehicle’s pairing flow.
- Accept the pairing and Android Auto prompts on both the phone and car display.
- If the phone pairs but Android Auto does not launch, confirm that Android Auto is enabled in the vehicle’s infotainment settings.
- Restart the infotainment system and repeat the normal connection attempt before deleting any remembered cars.
When the phone connects but the Android Auto interface does not start
Check the car display for an Android Auto enable or projection setting. Some vehicles allow the phone to connect over Bluetooth while leaving smartphone projection disabled. Enabling the feature and restarting the infotainment system addresses that state without changing Android Auto’s remembered-car list.
When only one vehicle is affected
A vehicle-specific failure points toward the car’s compatibility, infotainment firmware, USB port, or vehicle-side phone record. Google directs users to the vehicle manufacturer for compatibility and connection issues. Manufacturer menus differ, so do not assume that instructions for one model apply to another.

Use Forget all cars only after the non-destructive steps have failed and you are prepared to pair the phone and vehicle again. Google documents this control as part of troubleshooting, including situations involving connection to a second car. It is not the recommended first step for merely leaving developer mode.
- Open Settings and search for Android Auto.
- Open Android Auto settings.
- Open the connection area containing Previously connected cars.
- Select Forget all cars and confirm the deletion if Android asks for confirmation.
- Restart the phone and the car infotainment system if the manufacturer’s instructions call for it.
- Pair the phone and car again using the vehicle manufacturer’s Android Auto setup procedure.
After this action, Android Auto no longer has the prior remembered-car list on the phone. The exact prompts, Bluetooth names, USB-port requirements, and approval screens come from the vehicle and phone combination, so follow the manufacturer’s pairing instructions rather than assuming the old connection will return automatically.
Vehicle-side resets are a separate issue
A car may have its own menu for forgetting a phone or clearing paired devices. That action is controlled by the vehicle manufacturer and can remove the car’s copy of the connection. It is therefore capable of forcing another pairing even if you never touched Android Auto’s phone-side Forget all cars control.

Use a vehicle-side forget command only when the manufacturer recommends it for that vehicle or when you intentionally want to rebuild the pairing. If the issue is tied to a particular model, ask the manufacturer about Android Auto compatibility and infotainment firmware. Firmware labels, update methods, and reset behavior vary by vehicle.
Common mistakes that cause unnecessary re-pairing
- Choosing the wrong Menu item: Quit developer mode and Forget all cars are not interchangeable. Read the full label before confirming.
- Assuming a charge cable is a data cable: wired Android Auto needs a functioning USB data path.
- Turning off wireless prerequisites: Bluetooth, Wi-Fi, or Location Services being disabled can interrupt wireless setup.
- Changing several developer options together: multiple changes make it impossible to identify which setting caused a symptom.
- Resetting the phone before checking the car: a disabled projection feature, bad USB port, or outdated infotainment system can remain broken after a phone reset.
- Forgetting the vehicle while connected: vehicle-side deletion also creates a new pairing task.
- Testing while driving: changing Android Auto settings should be done while safely parked.
A connection-preserving checklist
- Park safely and record the current symptom.
- Open Android Auto settings from the phone’s Settings search.
- Use the Menu and choose Quit developer mode.
- Reconnect the same car without opening Forget all cars.
- For wired use, test the USB data cable and restart the infotainment system.
- For wireless use, keep Bluetooth, Wi-Fi, and Location Services on and repeat pairing normally.
- Confirm Android Auto is enabled on the car display if the phone connects but projection does not start.
- Contact the vehicle manufacturer about model compatibility, firmware, or a vehicle-side phone record.
- Only then consider Forget all cars, understanding that it removes the remembered list and requires pairing again.
What is—and is not—documented
Google documents the exit command and the separate remembered-car troubleshooting control. It does not publish an authoritative numeric success rate, timing guarantee, or universal command that clears every Android Auto developer preference while preserving all car pairings. Results can vary with Android version, Android Auto version, phone model, vehicle, cable, and infotainment firmware.
The practical conclusion is narrow but reliable: quit developer mode to leave developer settings while protecting the remembered-car list; reserve both phone-side and vehicle-side forgetting actions for deliberate re-pairing recovery.
Frequently Asked Questions
Can I turn off Android Auto developer mode without forgetting my car?
Yes. Open Android Auto settings from the phone’s Settings search, open the top-right Menu, and tap Quit developer mode. This is separate from Forget all cars, so it does not intentionally delete the remembered-car list.
Will quitting developer mode disconnect Android Auto?
Quitting developer mode is an exit from the developer-mode state, not a documented car-list deletion. Reconnect normally and test the same vehicle. A temporary reconnection may still be needed if the infotainment system was restarted.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
What happens if I tap Forget all cars?
Android Auto removes its remembered-car list on the phone. You should expect to pair the phone with each required vehicle again, following the vehicle manufacturer’s setup prompts.

Do I need to enable developer settings before I can quit developer mode?
No. If developer mode is already enabled, open Android Auto settings, tap Menu, and choose the exit command. The ten taps on Version or Version and permission info are only for exposing developer settings when they are not already available.
Is there a full Android Auto developer-settings reset that keeps every pairing?
Google documents Quit developer mode, but does not guarantee a separate command that restores every developer preference while preserving all pairings. Exit the mode first, then test and change one specific option at a time if necessary.
Why does wired Android Auto fail after I quit developer mode?
Check that the cable carries data rather than power only, use a known-good USB data cable, connect to the car’s Android Auto-capable port, and restart the infotainment system. A cable issue is independent of developer mode.
Recommended Free Tools
What must stay on for wireless Android Auto setup?
Keep Bluetooth, Wi-Fi, and Location Services enabled while pairing. Wireless Android Auto starts after Bluetooth pairing and depends on the other wireless and location conditions during setup.
Should I forget the phone from the car’s menu?
Only if you accept pairing again or the vehicle manufacturer specifically recommends clearing that stored phone entry. Vehicle-side forgetting is separate from Android Auto’s phone-side settings and is manufacturer-specific.
The Bottom Line
To leave Android Auto developer mode without deliberately losing your car connection, use Menu > Quit developer mode. Do not use Forget all cars unless you are ready to rebuild pairings. Test the existing connection first, then check the USB data path, wireless prerequisites, projection settings, and vehicle firmware or compatibility before taking a destructive reset.
