Wipe your personal data from your car before you sell it
Key takeaways
- Delete every paired phone and your contacts from the infotainment system, then clear your saved addresses, starting with Home.
- Remove the car from the manufacturer's app and cancel any subscription, following that brand's own steps, so your phone no longer shows or controls it.
- Take out your e-tag, garage remote, parking permits and fuel or charging cards, and remove the plate from your toll account.
- Leave the factory reset and the app removal until handover day, once the money has cleared, so you keep full use of the car while it's still yours.
Your car can remember your paired phones, contacts, call history, home and work addresses and recent trips, and it may still be linked to an app that shows where it is or unlocks it. To clear it all, delete the phones and saved places, take out your e-tag and garage remote, remove the car from the manufacturer’s app, then do a factory reset on handover day once the money has cleared.
None of it is hard, but it’s easy to forget while you’re focused on the price and the paperwork. This guide covers each place your details hide, then gives you a checklist for the day the car goes.
What does your car remember about you?
More than most people expect. Here’s where to look:
| Where | What it can hold | How to clear it |
|---|---|---|
| Phone or Bluetooth settings | Paired phones, contacts, call history, sometimes messages | Delete every phone from the device list |
| Navigation | Home, work, favourites, recent destinations | Delete saved places and clear the history |
| Driver profiles | Your name, seat and mirror settings, signed-in accounts | Delete the profile or sign out |
| Manufacturer’s app | The car’s location, remote lock and unlock, trip data | Remove the car from your account |
| Built-in garage buttons | Your garage or gate code | Clear them using the owner’s manual |
| Console, glovebox and windscreen | E-tag, remotes, permits, fuel cards, dashcam card | Take them with you |
If you signed in to a music, podcast or email account on the car’s screen, that counts too. Sign out before the car goes.
The phone list deserves a closer look. Your phone’s name usually appears on the screen, and it often includes your name. When you photograph the dashboard for an ad, check the screen isn’t showing that name, a contact or a map centred near your home. Our guide to what to share in car ad photos covers the rest of the picture.
Why does it matter once the car is sold?
Because the next person in the driver’s seat can see whatever you leave behind. Three things are worth worrying about.
Your home and how to get in. A navigation entry called Home, plus a garage remote in the console, tells a stranger where you live and how to open your garage. That’s the combination to break first.
Remote control of a car you no longer own. Connected services aren’t only for luxury cars and EVs any more. CarExpert reported connected services as part of the 2023 Toyota Corolla update, and Drive reported them as standard on the 2025 Mazda CX-30 Touring LE. Depending on the brand, the app that goes with them can show where the car is and lock or unlock it. While a car is still on your account, features like these can stay on your phone, and the new owner may have no idea.
Other people’s details. Your contact list holds the names and numbers of family, friends and workmates. Call history and synced messages show who you talk to and when.
Then there’s money. A toll tag left in the windscreen belongs to your toll account, so the next driver’s trips can end up on your bill. A parking app that recognises your plate can keep charging your card in the same way.
How do you unpair your phone and delete your contacts?
Do it from the car first, then from the phone. Menu names vary by brand, but the path is usually similar:
- With the car on, open the Phone, Bluetooth or Connections settings on the screen.
- Open the list of paired or registered devices.
- Select each phone and choose Delete, Remove or Forget. Do every phone on the list, including old ones and other family members’ phones.
- Check the phonebook, call history and messages have gone. Some systems keep a downloaded copy with its own delete option.
- On your phone, open the Bluetooth settings and forget the car. If you use Apple CarPlay or Android Auto, remove the car there as well.
If a menu isn’t obvious, the owner’s manual will have it, and many brands publish their manuals online. Unpairing doesn’t affect anything the next owner needs, so you can do it any time. If you rely on hands-free calls, leave it until handover day.
How do you clear navigation history and saved addresses?
Start with Home, because it’s the one that matters most. Then work through:
- Work and any other saved favourites, such as a school or a relative’s house
- Recent destinations and the search history
- Saved charging stations or routes, on an electric car or plug-in hybrid
- Trip logs or driving data, if your system records them
Many systems have a single option to clear all navigation data. Use it if yours does, then open the map and check that nothing is still saved.
If you’re selling privately, clear Home before the first viewing. A buyer in the driver’s seat on a test drive sees the same screen you do.
A dashcam keeps a record too. If yours has GPS, the memory card can hold where you’ve driven, along with video of your street and your driveway. Take the card with you, or if the camera stays with the car, format the card in the camera so the next owner starts with a blank one.
How do you remove the car from the manufacturer’s app?
Follow your manufacturer’s own steps, in its app or on its website, because every brand does it differently. Look in the app’s vehicle settings for an option such as remove vehicle, delete vehicle or transfer ownership. If you can’t find one, contact the brand’s customer service with the car’s VIN.
While you’re in the app:
- Cancel any paid subscription or data plan, so you aren’t charged for a car you no longer own.
- Remove anyone you’ve shared access with, such as a partner set up as a second driver.
- Save your service records. If your service history lives in the app or an online logbook rather than a paper book, download or print a copy before you start getting offers. Buyers check it, it belongs with the car, and you may lose access once the car is off your account.
- Check it’s gone. Close the app, open it again and make sure the car no longer appears.
Treat the app and the car as two separate jobs. Resetting the screen in the car may not remove it from your account on the manufacturer’s system, and removing it from the app may not wipe what’s stored in the car.
Tesla shows why timing matters. Your phone is the everyday key through the Tesla app, so you still need it until the car leaves. Our guide to selling a used Tesla Model 3 or Model Y sets out the order Tesla gives for the factory reset and for removing the car from your account. If another brand lets your phone work as a key, the same rule applies: the physical keys stay with the car, and your phone’s access is removed at handover.
What about e-tags, garage remotes and parking apps?
Take them out, then cut the link to your accounts. A tag in the windscreen and a plate on your account can both keep you paying.
Toll tags. The NSW Government’s advice to sellers is to “remove the e-tag from the vehicle and delete the registration number from your account”. Queensland’s selling guidance tells sellers to remove any toll tags and update their details with Linkt. Whatever state you’re in, if you have a tag or a toll account, take the tag out and remove the plate from the account. Log in to do it, or call your toll provider if you can’t find the option.
Garage and gate remotes. Take the handheld remote out of the console or sun visor. If your car has garage buttons built into the mirror or roof console, clear them using the owner’s manual. If a remote has already gone with a car, have your garage door opener recoded so the old remote stops working.
Everything else that knows your plate or your card. Work through:
- Parking apps and car parks that recognise your plate and charge a saved card
- Council parking permits and building or apartment car park registrations
- Fuel cards, car wash memberships and EV charging cards or apps
- Your home charger’s app, if the car is linked to it
- A tracker such as an AirTag, if you hid one in the car for test drives, as the NRMA suggests for private sellers
Your rego direct debit can’t wait for the sale. Queensland’s transport department and VicRoads both tell sellers to take the car off any rego direct debit before they sell. Keep your insurance running until the car has been collected. Our after-sale checklist covers insurance, roadside assistance and the rest.
Should you factory reset the car, and when?
Yes, in most cases. A factory reset, sometimes called restoring default settings or initialising the system, clears most of what the infotainment system has stored in one go. Look in the system or general settings, or search the owner’s manual for “reset”.
Two cautions. First, check what the reset covers. On some cars it clears phones, contacts and navigation together, while on others each has its own delete option, so go back through the screens afterwards. Second, the reset doesn’t replace removing the car from your app.
Timing is the part people get wrong. The reset is the last thing you do, not the first:
- Before the sale is agreed, you’re still driving the car. Clear Home and anything you’d rather a stranger didn’t see, but keep your phone paired if you need it.
- Before the inspection, there’s no need to reset anything. The car is still yours, so keep using it as normal.
- On handover day, once the money has cleared, do the reset, remove the car from the app and take out the tag and remote.
Done in that order, you keep full use of the car until it’s sold, and nothing personal leaves with it.
What if the car has already gone?
You can still fix most of it from home:
- Remove the car from the manufacturer’s app and cancel any subscription. That part is online and doesn’t need the car.
- Remove the plate from your toll account and any parking apps.
- Have your garage door opener recoded if a remote went with the car or you didn’t clear the built-in buttons.
- Contact the buyer or the dealer and ask for a factory reset of the infotainment system.
- If you signed in to an email, music or other account on the car’s screen, change that password.
Handover-day checklist
Work through this on the day the car goes, after you’ve confirmed the money is in your account:
- Delete every paired phone, then forget the car on your phone and in CarPlay or Android Auto.
- Check the phonebook, call history and messages are gone.
- Clear Home, Work, favourites and recent destinations.
- Delete driver profiles and sign out of any accounts on the screen.
- Clear the built-in garage buttons and take the handheld remote.
- Do the factory reset, then check the screens again.
- Remove the car from the manufacturer’s app, once any digital service records are saved.
- Take out the e-tag, parking permits, fuel and charging cards, dashcam card, USB sticks and any tracker.
- Leave every key or key card, the owner’s manual, the service logbook and, on an electric car or plug-in hybrid, the charging cable.
- After collection, remove the plate from your toll account and parking apps.
Our guide to preparing your car for sale covers the rest of the preparation, and car collection and key drop-off explains how the handover itself works.
Selling to us: a fixed day to wipe it
The hardest part of wiping your data is knowing when to do it. In a private sale, a buyer can want to drive off the moment they say the money is sent, before you’ve reset anything or checked that the payment has actually arrived.
When you sell to Sell Your Car Australia, the order never changes. You get a genuine offer by phone from a licensed dealer, not an online estimate. If you accept, a deposit is often paid the same day, and the inspection follows at a time and place that suits you. The balance goes into your bank account, and the car is collected only after you confirm the funds have cleared. That gives you a known handover day to reset the screen, remove the car from the app and take out the tag.
We’re Autohaus Australia Pty Ltd, a NSW licensed motor dealer (MD 077404), and we arrange collection anywhere in Australia. We buy cars, utes, SUVs and 4WDs 2021 or newer with 100,000 km or less. If yours is older or has more kilometres, send it through anyway and we’ll tell you straight away if we can help. Start with a free, no-obligation valuation or call 1800 73 55 73.
Questions sellers ask
Do I need to wipe anything if I only used Apple CarPlay or Android Auto?
Usually, yes. Even when your phone does most of the work, the car generally keeps it in its list of known devices, and some systems store recent calls or contacts as well. Delete the phone from the car's device list, then remove the car in your phone's CarPlay or Android Auto settings.
What if I can't log in to the brand's app any more?
Contact the manufacturer's customer service with the car's VIN and ask them to remove the car from your account. Have proof that you owned it ready, such as your rego papers or the bill of sale. It's worth doing even after the car has gone, so it's no longer linked to your name.
Will wiping my data lower what the car is worth?
It shouldn't. Your contacts and saved addresses aren't part of the car, and the next owner expects a clean screen. What does matter is what stays with it: every key or key card, the owner's manual, the service records and, on an electric car or plug-in hybrid, the charging cable.
Can the people who handle my car after the sale see what I left behind?
Anyone who sits in the car with the ignition on can usually see what's on the screen, from contacts and call history to saved addresses. A car can pass through several hands before its next owner drives it home. Wiping it yourself before it leaves is simpler than relying on someone else to do it.
