With navigation
Remove the driver's dashboard undercover.
Disconnect the 32P connector (A) from the HandsFreeLink control unit (B).
Inspect the connector and socket terminals for a good pinfit to be sure they are all making good contact.
If the terminals are bent, loose or corroded, repair them as necessary, and recheck the system.
If the terminals look OK, go to step 4.
Reconnect the connector and make these input tests at the connector under the test conditions listed.
If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, go to 5.

Disconnect the 32P connector again, and make this input test at the connector.
If any test indicates a problem, find and correct the cause, then recheck the system.
If all the input tests prove OK, the HandsFreeLink control unit must be faulty; replace it.
