Re-pairing my iPhone to my Honda CR-V

My phone was paired with my car. I had my phone forget the handsfree link so I could use my headphones in the car instead of it coming through the speakers. Now my phone will no longer find handsfreelink when the Bluetooth is on. It will not pair again. It says cannot pair. Forget device and try again. How do I get my phone to find my car’s handsfreelink again?
