PCM questions ??
 

Recently purchased a 2006 997S. There are buttons for nav & phone but when I choose either, the message line says both are not available. Is there something I need to do to activate these features? Also the stalk on the column that is for pcm choices doesn't seem to do anything when I try to use it. (Note: had a dead battery 2 weeks ago. Charged it and it seems ok now..) Thanks
