Troubleshooting: Bluetooth

I can't pair with a Bluetooth enabled device

Check that your BlackBerry device is compatible with the Bluetooth enabled device. For more information, see the documentation that came with the Bluetooth enabled device.
If your Bluetooth enabled device requires a passkey and you don't know what the passkey is, check the documentation that came with your Bluetooth enabled device. Sometimes the passkey is set to 0000 until you change it. If you don't know what the passkey is, try 0000.
If your BlackBerry device doesn't detect the Bluetooth enabled device that you want to pair with, try making your BlackBerry device discoverable for a short period of time. On the home screen, swipe down from the top of the screen. Tap Bluetooth. In the Discoverable drop-down list, tap On or 2 Minutes.
If the Bluetooth enabled device uses a battery, connect the device to a power source and then try again. Depending on the device, if the battery power level is too low the device might still operate but be unable to pair.
If Mobile Hotspot mode is turned on, verify that you're trying to connect to a Bluetooth enabled device that uses the Handsfree, Headset, Serial Port, or Dial-Up Networking profiles.

Check that your car kit is using the latest software version that is available. For more information about your car kit's software version, see the documentation that came with your car kit.
Move your BlackBerry device to another location in your vehicle or turn your device to face another direction. The location of your device's antenna in relation to your car kit's Bluetooth antenna may affect the Bluetooth connection.
