Quick Summary:
- Delete all paired phones, then restart the infotainment to clear caches.
- Remove Apple CarPlay and Android Auto profiles, plus connected app accounts.
- Clear navigation recent destinations, favourites, and stored Home or Work addresses.
- Erase HomeLink garage door codes, then confirm your phone pairs cleanly.
When you pick up a car hire in United Estates, the infotainment system can still hold data from the previous renter. That can mean their phone auto-connecting, their contacts and call logs appearing, or their favourite destinations and “Home” address staying in the sat nav. The good news is you can usually wipe it in a few minutes at the kerbside, even without knowing the exact make and model.
This guide gives you a practical, step-by-step reset checklist covering Bluetooth, Apple CarPlay, Android Auto, navigation history, connected car profiles, and HomeLink. The aim is simple, protect your privacy, prevent pairing problems, and avoid accidentally opening someone else’s garage door.

Before you start: a two-minute cabin check
Do this first so you do not miss hidden connections.
1) Turn the car fully on. Put it in accessory mode or start the engine, then wait for the infotainment screen to finish loading.
2) Find the “Connections” area. Most systems place these under Settings, Connections, Bluetooth, Phone, Device Manager, or General.
3) Note what is already there. If you see multiple phones, profiles, or a driver name you do not recognise, you will want to remove them all rather than only disconnecting.
Step 1: Remove paired phones and Bluetooth data
Bluetooth is the most common source of “ghost” pairing. Even if the last renter is miles away, their device name can remain and can interfere with your pairing or route audio to the wrong place.
A. Delete the car’s saved devices
Open the list of paired devices and choose Remove, Forget, Delete device, or Unpair for every phone you do not own. If there is a “Delete all devices” or “Clear Bluetooth devices” option, use it.
B. Delete your phone’s saved car entry too
On iPhone, go to Settings, Bluetooth, tap the info icon next to the car name, then Forget This Device. On Android, go to Settings, Connected devices, Bluetooth, tap the gear next to the car, then Forget or Unpair. This matters because your phone may try to reconnect using old permissions.
C. Restart the infotainment system
If the car offers a Restart or Reboot option, use it. If not, turn the vehicle off, open and close the driver’s door, lock the car, wait about 60 seconds, then turn it back on. This helps clear temporary connection caches that can keep old devices “half remembered”.
D. Pair your phone fresh
Now pair your phone using the car’s Add Device flow. Confirm the pairing code matches on both screens, then approve contacts and messages only if you want hands-free calling and voice assistant features.
Step 2: Wipe Apple CarPlay, Android Auto, and app permissions
CarPlay and Android Auto can store a relationship between the car and a phone even after Bluetooth is cleared. Some vehicles also retain app tokens for Spotify, Alexa, Google Assistant, or manufacturer apps.
A. Remove CarPlay pairing on the car
Look for Apple CarPlay under Settings or Phone Projection. Remove any existing phones. Some systems show CarPlay devices separately from Bluetooth devices, so check both lists.
B. Remove CarPlay pairing on your iPhone
On iPhone, go to Settings, General, CarPlay, select the car, then tap Forget This Car. This prevents your iPhone reconnecting to the wrong car profile later.
C. Remove Android Auto pairing on the car
Find Android Auto or Phone Projection, then delete previously connected phones. If there is a “Reset Android Auto” option, use it.
D. Clean Android Auto on your Android phone
Open Android Auto settings and remove previously connected cars. On some Android versions, you will find it under Settings, Connected devices, Android Auto. Clearing this helps if the car refuses to recognise your handset, or tries to load another driver’s settings.
E. Check for signed-in accounts on the car
Some infotainment systems allow signing into music apps, voice assistants, or the vehicle’s connected services. Browse for Accounts, Users, Profiles, Connected Services, or Apps and remove any account you do not own. If the car has a Guest mode, switch to it for the cleanest experience.
Step 3: Clear navigation history, favourites, and “Home”
Sat nav data is often more sensitive than people realise. Recent destinations can reveal hotels, addresses, workplaces, and medical facilities. Clearing these protects the previous renter and ensures you do not get strange suggested routes.
A. Clear recent destinations
Open Navigation, then look for Recent, History, Destinations, or Last locations. Select Clear, Delete, or Remove all. If the car uses a map card or embedded system, this list can persist between drivers until removed.
B. Delete saved favourites and saved places
Check Favourites, Saved, Starred, or Shortcuts. Delete anything you do not recognise. Pay special attention to “Home” and “Work” slots, as these can be set even when favourites look empty.
C. Disable predictive suggestions if you prefer
Some systems offer “Learned routes” or “Predictive destinations”. If you are only using the car briefly, turning these off can reduce what the car stores about your driving habits.
D. If you will rely on your phone, consider skipping built-in nav
Using CarPlay or Android Auto for maps can reduce the amount of data stored in the vehicle itself. You still need to clear the last renter’s data, but you may have less of your own to remove later.
Step 4: Remove driver profiles, seat memory links, and key associations
Many modern cars link infotainment settings to driver profiles, sometimes tied to a key fob. These profiles can store phone pairing, navigation favourites, radio presets, climate preferences, and even seat and mirror positions.
A. Find “Profiles” or “Users”
Look in Settings for Driver Profiles, Users, Accounts, or Personalisation. If you see a named profile that is not yours, delete it or switch to Guest.
B. Unlink keys if the menu allows it
Some vehicles let you associate a specific key with a profile. If there is an option to reset key-user links, use it. This can stop the car automatically loading the previous renter’s settings the moment you unlock it.
C. Reset seat memory buttons if needed
Memory seats are not always tied to profiles, but if the car keeps returning to an odd seating position, check if a memory button is set. You can usually overwrite by adjusting the seat, then holding the Set button and a memory number as instructed on the seat controls.

Step 5: Wipe HomeLink and garage gate codes
HomeLink is the built-in garage door and gate remote system found in many cars. If it is set up, pressing the programmed button could open someone else’s garage. Even if the odds are low, it is worth clearing for privacy and safety.
A. Check if the car has HomeLink
Look for three small buttons on the overhead console, sun visor area, or near the rear-view mirror. If present, assume it may be programmed.
B. Clear HomeLink memory
The common method is to press and hold the two outer HomeLink buttons until the indicator light changes, often after about 10 seconds. Some cars require ignition on. Because procedures vary, confirm the infotainment or visor label instructions if shown. The goal is to erase all stored codes, not just one button.
C. Confirm it is cleared
After resetting, the indicator light usually behaves differently, or the buttons no longer trigger an action. If you are unsure, ask the desk staff to confirm HomeLink has been reset before you leave.
Step 6: Decide between a full factory reset and a targeted wipe
When time is short, targeted wiping can be enough. If the car looks heavily personalised, or you see unknown accounts signed in, a factory reset can be safer.
Use a targeted wipe when: you only see a couple of paired devices, nav recents, and nothing else signed in.
Use a factory reset when: there are multiple profiles, app logins, persistent pairing failures, or you want maximum privacy.
Look for Settings, System, General, Reset, Factory data reset, or Restore defaults. Some vehicles offer separate resets for Bluetooth, navigation, and personal data. Choose the option that removes personal information rather than one that only resets audio settings.
After a factory reset, the system may take a few minutes to reboot. Re-pair your phone, confirm audio works, and set language and units before driving off.
Step 7: A quick “proof” test before you drive away
Run this 60-second confirmation so you do not discover issues on the motorway.
1) Bluetooth list: only your phone should appear as saved.
2) CarPlay or Android Auto: connects once, without prompts about another user.
3) Navigation: Recent destinations list is empty, and no Home or Work is set.
4) Voice assistant: press the voice button and confirm it addresses your phone, not a built-in account.
5) HomeLink: indicator behaves as unprogrammed, or buttons do nothing.
If you still see previous data after clearing, it is reasonable to return to the counter and request help or a different vehicle, as some systems require staff-level menus to complete a wipe.
Privacy tips for your own data during the rental
Once you have cleared the last renter’s info, avoid leaving more of your own than necessary.
Prefer USB data connections you control. If you use a cable for CarPlay or Android Auto, unplug it every stop and keep your phone locked.
Skip contact sync if you do not need it. Many cars ask to download contacts and messages. Declining reduces what is stored locally.
Use guest profiles where available. Guest mode often prevents saving navigation favourites and other personal settings.
At return, repeat the wipe quickly. Delete your phone pairing, clear navigation recents, and remove HomeLink if you set it up. That helps the next driver and protects you.
FAQ
Will deleting Bluetooth devices also remove Apple CarPlay or Android Auto? Not always. Many cars keep projection profiles in a separate menu, so delete Bluetooth devices and also remove CarPlay and Android Auto entries for a complete wipe.
Is a factory reset safe to do on a car hire in United Estates? Yes, it usually resets infotainment personalisation only. It should not affect the vehicle’s ability to drive, but it can change language, clock, and radio presets, so do it before you set off.
Why does the car still try to connect to a previous phone? The infotainment may have cached the device, or there may be a second Bluetooth list under Phone Projection. Restart the system after deleting devices, and forget the car on your phone as well.
How do I know if HomeLink is programmed? If the car has the three HomeLink buttons, assume it might be set. Clearing it is quick and prevents accidental activation of a garage or gate.
What should I clear right before returning the vehicle? Remove your phone from Bluetooth and projection menus, clear navigation recents and favourites, sign out of any apps, and reset HomeLink if you programmed it.
