If you have a Bluetooth device paired to your car, then after you start it should automatically connect to your phone. But often you might get the message "No Bluetooth device is connected". There is no permanent fix to the issue on older variants of Nissan cars, however there is a workaround that can make your life easier. After you start your vehicle, press and hold the Power button of the infotainment system until the system reboots itself. The Nissan Logo appears and then on the top right corner beside the time, you should see the Bluetooth symbol.
