Step 1: Verify Phone Compatibility

Consult Owner’s Manual: Check the Bluetooth compatibility section in your Toyota Camry owner's manual to ensure your smartphone is supported.
Check Bluetooth Version: Ensure that your phone's Bluetooth version is compatible with the car's Bluetooth system. Most modern phones should work, but older models may have issues.

Step 2: Restart Devices

Turn Off Bluetooth on the Phone: Go to the Bluetooth settings on your phone and toggle Bluetooth off.
