Note that the mute wire (pin RT2-3) is grounded by the cellular phone transceiver when a call is received and during a call. When this wire is grounded, the radio will switch the audio input from music to the line level audio input wires (RT2-1 and RT2-2) allowing the phone to be heard through the stereo speakers. The radio will show “PHONE” across the display while the mute wire is grounded.

Wiring Color Code:

N – Brown
B – Black
W – White
K – Pink
G – Green
R – Red
Y – Yellow
O – Orange
S – Slate
U – Blue
P – Purple
BRD – Braid

When a wire has two or more color code letters, the first letter indicates the main color and the subsequent letters indicate the tracer colors.

The microphone wiring runs from connector RT2 up to the roof console. Remove the roof console by opening the sunglasses holder and twist the plastic mounting pin 90 degrees. Once removed, you will see connector CA67, a blue 2-terminal connector.
