Use the ISO cable CA-135
When you connect the car kit to the car radio system with the ISO cable 
CA-135, you can select if the car kit amplifier is used for calls and the 
car radio amplifier is used for music, or if the car kit amplifier is used for 
both.
Use the car kit amplifier for calls and music
In this setup, the car radio is muted when you make or receive a call or 
listen to music from a connected device that supports the A2DP 
Bluetooth profile.
The built-in amplifier of the car kit is used for calls and music played on 
the A2DP device.
1. To connect the ISO cable to the car radio:
• Unplug the appropriate cables from the car radio, and insert the 
ISO cable plug instead. Connect the open ends of the cables to 
the car radio speakers.
