RELATED TO HANDS-FREE PHONE

Before performing diagnosis, confirm that the cellular phone being used by the customer is compatible with the Nissan Pathfinder vehicle.
It is possible that a malfunction is occurring due to a version change of the phone even though the phone is a compatible type. This can be confirmed by changing the cellular phone to another compatible type, and check that it operates normally. It is important to determine whether the cause of the malfunction is the Nissan Pathfinder vehicle or the cellular phone.

2. If the customer’s phone is NOT on the approved list:
  
  Stop diagnosis here. The customer needs to obtain a Bluetooth^® phone that is on the approved list before any further action.
3. If the feature related to the customer’s concern shows as “N” (not compatible):
  
  Stop diagnosis here. If the customer still wants the feature to function, they will need to get an approved phone showing the feature as “Y” (compatible) in the “Basic Features”.
