Here is my set up in my CLK
Charges phone
Plays music thru my in car audio system
When someone calls, music stops and I answer the phone on the mount, hit speaker and Bobs your uncle.
Same when I want to make a call, dial the number (or use a contacts number) hit call and hit speaker and again talk awy untill your hearts content
NO feed back no nothing, just a bummer when you are in the car with your wife and your girlfriend calls
