Installation (cont.)
Safety Connect (SOS) Retention
In order to retain the factory feature of muting the radio's audio while an SOS call is taking place, the Yellow / Black "SOS
Mute" must be connected to the Telematics Mute Trigger wire in the vehicle. The Telematics Mute trigger wire is in the white
24pin connector at the factory amplier (reference connector image and pin location below). A military splice connection to this
wire will be adequate.
