The BMW 5 Series has Bluetooth connectivity so you can talk on your cell phone using the built-in speaker phone in your car. Before your phone and car can connect, they have to go through the Bluetooth connection process, called pairing. When you pair your car and phone, you are creating a secure personal network over which the two devices can communicate.
Access the Bluetooth menu on your phone and enable the Bluetooth function. This exact process will vary based on your cell phone model, but there should be an “On/Off” option in the Bluetooth menu.
Press down on your BMW’s controller, located just under the gear selector, to access the onboard computer’s menu.
