The basic steps for connecting Bluetooth in most cars
To connect your phone to your car's Bluetooth system, you turn on Bluetooth on your phone, put your car in pairing mode, and select your car from the list of available devices. The exact steps depend on your phone's operating system and your car's infotainment system, but the general process is the same across most vehicles made in the last ten years.
Most cars enter pairing mode automatically the first time you try to connect a device. After that first connection, your phone and car remember each other, and they reconnect automatically when you get in the car and turn it on. You do not have to repeat the pairing process every time you drive.
The whole process usually takes two to five minutes the first time. After that, reconnection happens in the background without any action from you.
Key Takeaways
- Turn on Bluetooth in your phone's settings, then put your car in pairing mode — usually by pressing and holding a button on the steering wheel or selecting an option in the infotainment menu.
- Your phone will show your car's name in the list of available Bluetooth devices; select it to complete the pairing.
- After the first connection, your phone and car automatically reconnect each time you get in the vehicle.
- If your car has both Bluetooth audio and phone calling, you may need to pair separately for each function, depending on the car's system.
- If reconnection fails, forgetting the device on your phone and re-pairing usually solves the problem.
How to put your car in pairing mode
Most cars enter pairing mode in one of two ways. The first is automatic: when you turn on the car and no phone is connected, the system waits for a new device to pair. The second is manual: you hold down a button on the steering wheel or select a menu option in the infotainment screen.
On the steering wheel, look for a button labeled with a Bluetooth symbol or the word "Phone." Holding it down for three to five seconds usually activates pairing mode. Some cars use a different button — check your owner's manual if you are not sure which one.
If your car has a touchscreen, you can also enter pairing mode through the settings menu. Look for "Bluetooth," "Connections," or "Devices," then select "Add Device" or "Pair New Device." The exact wording varies by manufacturer.
Connecting on iPhone versus Android
On an iPhone, open Settings, tap Bluetooth, and turn it on. Your car should appear in the list of available devices under "Other Devices." Tap your car's name to start pairing. Your car's infotainment screen will show a pairing request; confirm it on both the phone and the car to complete the connection.
On Android, open Settings, select Bluetooth, and turn it on. Your car will appear in the list of available devices. Tap your car's name to pair. Like iPhone, you will need to confirm the pairing on both your phone and your car's screen.
After the first pairing, both iPhone and Android will reconnect automatically. If your car has a PIN code for pairing — usually 0000 or 1234 — enter it on your phone when prompted. Check your owner's manual if you do not know the PIN.
What to do if your phone will not connect
If your phone does not show your car in the list of available devices, make sure your car is actually in pairing mode. Hold the steering wheel button longer, or go back into the infotainment menu and try again. Some cars only stay in pairing mode for a few minutes, so you may need to restart the process.
If your car appears but the connection fails, try forgetting the device on your phone and pairing again from scratch. On iPhone, go to Settings > Bluetooth, find your car, tap the "i" icon, and select "Forget This Device." On Android, go to Settings > Bluetooth, tap the gear icon next to your car, and select "Unpair." Then restart pairing as if it were the first time.
If the problem persists, restart both your phone and your car. Turn off your phone's Bluetooth, wait ten seconds, turn it back on, and try pairing again. Restarting your car's infotainment system — usually by turning the car off and back on — can also help.
Pairing for both audio and phone calls
Some cars separate Bluetooth audio (for music and podcasts) from Bluetooth calling (for phone calls and contacts). If your car has this split, you may see two different options in the pairing menu: one for "Audio" or "A2DP" and one for "Phone" or "HFP." You can pair both at the same time, or pair just one if you only need that function.
If you pair both, your car will use Bluetooth for calls and audio simultaneously. If you pair only audio, your car will not have access to your phone's contacts or call history, and you will need to use your phone to make calls.
Most modern cars pair both functions automatically without you having to choose. If your car asks you to select, choose both unless you have a specific reason not to.
Connecting multiple phones to the same car
Most cars can store multiple phones in their Bluetooth memory and will reconnect to whichever phone is closest or turned on. You can pair a second phone by putting the car back in pairing mode and following the same steps. The car will remember both phones and switch between them automatically.
Some cars limit how many phones can be paired at once — typically two to five. If you reach that limit, you will need to forget an old phone before pairing a new one. Check your owner's manual for your car's specific limit.
When two paired phones are in the car at the same time, the car usually connects to whichever one was most recently used. If you want to switch to a different phone, you can manually select it in the Bluetooth menu on your car's infotainment screen.
Troubleshooting common connection problems
If your phone connects but audio does not play through the car speakers, check that Bluetooth audio is turned on in your car's settings. Some cars have separate toggles for Bluetooth audio and phone audio. Also check that your phone is not still playing audio through its own speaker — tap the AirPlay icon on iPhone or the audio output icon on Android and select your car.
If your car connects to your phone but then disconnects after a few seconds, the car may be exiting pairing mode automatically. Try pairing again and wait for a confirmation message on both devices before assuming the connection is complete.
If your car shows your phone as connected but you cannot make or receive calls, the phone function may not have paired successfully. Forget the device and pair again, making sure to confirm both audio and phone pairing when prompted.
Frequently Asked Questions
Do I have to pair my phone every time I get in the car?
No. After the first pairing, your phone and car remember each other. They will reconnect automatically every time you turn on the car and your phone's Bluetooth is on. You only pair once, unless you forget the device or reset your car's system.
Can I use Bluetooth in my car if it does not have a touchscreen?
Yes. Older cars without touchscreens still have Bluetooth if they were made after roughly 2010. You enter pairing mode by holding a button on the steering wheel, and you navigate menus using steering wheel controls or buttons on the dashboard. Check your owner's manual for the exact controls.
What if my car does not have Bluetooth at all?
You can add Bluetooth to an older car with an aftermarket receiver or a Bluetooth adapter that plugs into your car's aux jack or cigarette lighter. These range from $20 to $100 depending on features. Some also work with your car's steering wheel controls.
Will Bluetooth drain my phone's battery?
Bluetooth uses very little battery power — typically less than 1 percent per hour. You will not notice a meaningful difference in battery life from using Bluetooth in your car.
Can I connect two phones to my car at the same time?
Most cars can pair multiple phones but only connect to one at a time. If two phones are in the car, the car will use whichever one was paired most recently or is closest. You can manually switch to a different phone in the Bluetooth menu on your car's screen.
