Navigation System Symptom Troubleshooting - Navigation does not call using the HFL

Navigation does not call using the HFL

NOTE:

- Always have the client demonstrate their concern. Compare the operation of this feature in a known-good vehicle.
- Review the navigation system manual for the proper operation of this feature. If the navigation database does not have a phone number listed for the POI you are trying to call (for example, a public park), the navigation system cannot place a call through the HFL.
- You must have the client's phone, the phone must be on the list of the HFL approved phones and configured correctly.
- For a current list of HFL approved phones, go to www.acura.com/handsfreelink or call the HFL support desk at 888-528-7876
