Purchase a Gizmo Guy Gadget Bluetooth adapter specifically designed for your older vehicle without Bluetooth or Aux connectivity and make sure to check the compatibility of the adapter with your car’s make and model before purchasing. You can find a variety of Bluetooth adapters online or at a local electronics store.
Locate the diagnostic port in your car. The diagnostic port is typically located under the dashboard on the driver’s side of the vehicle. It is a rectangular port with a removable cover that is usually labeled with the word “diagnostics” or “OBD-II.”
Connect the Bluetooth adapter to the diagnostic port. Once you have located the diagnostic port, simply plug the Bluetooth adapter into the port.
Turn on your car’s ignition. This will power on the Bluetooth adapter and allow it to start searching for nearby devices.
Enable Bluetooth on your phone or other device. On your phone or other device, go to the Bluetooth settings and turn on Bluetooth. Your phone should now start searching for nearby Bluetooth devices.
Pair your phone or device with the Bluetooth adapter. Once the adapter is detected by your phone, follow the prompts to pair the two devices. You may need to enter a PIN code to complete the pairing process.
Test the connection. Once the pairing is complete, you should be able to make and receive calls through your car’s speaker system. You can also use the adapter to stream music from your phone or other device to your car’s audio system.
Set up voice commands. Many Bluetooth adapters come with a microphone that allows you to use voice commands to control the system. To set up voice commands, you may need to follow additional instructions provided by the manufacturer of the Bluetooth adapter.
Enjoy the convenience of hands-free calling and wireless audio streaming while driving. With your Bluetooth adapter installed, you can now make and receive calls and stream music while keeping your hands on the wheel and your eyes on the road.
