connector B (16-pin) off the nav unit, terminal 3 (WHT/BLK) is the mute line. you can also find this line in the 20-pin connector to the stereo, terminal 16 (WHT/BLK).
i bought both the service manual and the electrical troubleshooting book. they are awesome!! definitely recommended if you are going "customing" your MDX
