Ok, so I discovered the bluetooth module located in the rear of the vehicle, then proceeded to pair my phone but nothing happens. The steps I followed were:

1. Turn ignition to acc on, position 1.
2. Press and hold the phone button on the steering wheel for 3 seconds.
3. Turn ignition to ign on, postion 2, while holding the phone button.
4. Did a scan on the phone for bluetooth device.

Nothing happens. Please lmk, if I'm doing something wrong or do I have to replace the bluetooth unit.
