CDR220 Phone Installation HELP

[Lil bastard]

Attached is everything printed in both the CDR220 and Factory Workshop manual relating to the Telephone for the Boxster. Hopefully it's useful...

Thanks guys. I do have the full on board computer and there is a inbuilt mic. In my manual, there is reference to simply using any left or right speaker to hear conversations and automatically mute the radio. Does the phone have to be "physically" connected to anything to make this work? I guess it's not "bluetooth or infra red". What type of phone? Thanks again.
