When your Galaxy S25 Ultra refuses to connect to your car’s Bluetooth, driving can quickly become frustrating. Calls fail, music won’t play, and hands free features stop working when you need them most.
This issue is usually caused by pairing conflicts, outdated software, or simple Bluetooth misconfigurations. The fixes below will help you reconnect safely and reliably.
Why Your Galaxy S25 Ultra Can’t Connect to Car Bluetooth
- Bluetooth pairing data is corrupted or outdated.
- The car system is already connected to another device.
- Bluetooth permissions are restricted on the phone.
- Software on the phone or car system is outdated.
- Temporary Bluetooth glitches after updates or restarts.
Restart Bluetooth on Your Phone.
Bluetooth can silently fail in the background. Turning it off and back on refreshes the connection process.
- Open Settings, and then tap Connections.
- Tap Bluetooth, and then toggle it off and back on after a few seconds.
After doing this, try connecting to your car again from the Bluetooth list.
Forget the Car and Pair It Again.
Old pairing data can prevent a new connection from completing. Removing the saved device forces a clean handshake.
- Open Settings, and then tap Connections.
- Tap Bluetooth, and then tap the gear icon next to your car’s name and select Unpair.
Restart your car’s infotainment system, then pair the devices again from scratch.
Make Sure the Car Is in Pairing Mode.
Your phone will not connect if the car system is not discoverable. Some vehicles exit pairing mode automatically.
- Open Settings, and then tap Connections.
- Tap Bluetooth, and then wait for your car name to appear while pairing mode is active.
If the car does not appear, restart the vehicle or check its Bluetooth menu.
Check Bluetooth Permissions.
Restricted permissions can stop Bluetooth from working correctly with car systems.
- Open Settings, and then tap Apps.
- Tap Bluetooth, and then tap Permissions and allow Nearby devices.
Once enabled, reconnect to your car and test audio or calls.
Update Your Phone Software.
Bluetooth bugs are often fixed in system updates. Keeping your Galaxy S25 Ultra current improves compatibility with car systems.
- Open Settings, and then tap Software update.
- Tap Download and install, and then apply any available update.
Restart your phone after updating to complete the process.
Reset Bluetooth Settings.
If nothing else works, resetting Bluetooth clears hidden connection errors without deleting personal files.
- Open Settings, and then tap General management.
- Tap Reset, and then tap Reset Bluetooth and Wi-Fi settings.
Reconnect your car Bluetooth after the reset finishes.
Bluetooth issues with cars are common, but they are rarely permanent. Once the connection is restored, your Galaxy S25 Ultra should pair automatically every time you start the vehicle.
FAQs
Why does my Galaxy S25 Ultra connect to other devices but not my car?
Car systems often use older Bluetooth profiles. Clearing the pairing and updating software usually resolves compatibility issues.
Do I need to reset my phone to fix car Bluetooth issues?
No. A Bluetooth reset or re-pairing is usually enough and does not erase personal data.
Why does Bluetooth disconnect while driving?
This can happen if another device connects automatically or if the car system has weak signal stability. Removing unused paired devices often helps.
