There is a setting under PHONEBOOK somewhere. When entering names and numbers you will need to hold down the Tune button once the last number/characted is entered. There are two ways to make a call: Dial the number from your phone to initiate the call. The call should transfer to the handsfree once it starts dialing. For the programmed speed dials, hit the green handset, press 1-6, hit the green handset. To end a call either disconnect with your handset or use the red handset button on the unit. Turning the volume button during a call changes the speaker volume of the call. There are some other functions, but you will need to explore the menus. The handsfree functionality is pretty basic. You can only access the calling functions for the handsfree when the vehicle is in motion. Hope this helps.
