Installing the Hands-Free for the Crossfire Non-Navigation Factory Radio/CD player

Before removing my factory radio/CD player, I installed the necessary wiring to use a hands-free phone device.  It was inexpensive and very simple.  Here is the general layout of connections for the head unit. 

An auxiliary input is provided that gives a mono connection for the cell phone system. (diagram).  One could use something like a Motorola Bluetooth to route phone sound through the stereo and pause the music to take or make a call.  I highly recommend adding the phone connection.  (Instructions below are for the factory unit installed in the Crossfire though the instructions refer to Porsche which also have the same unit).  I purchased the wires needed (Part# BNA - 1319 - 116) from Becker USA, online.

Here are the instructions they provided, (along with the radio removal tools and wires).  It's a ten minute job.  You may need to add an RCA connector to the sound output from the hands-free to the radio.
