INSTALLATION
With the key in the off position:
• Connect the 16-pin harness with stripped leads, and the GMOS-MOST-01 harness into the
interface.
• Connect the GMOS-MOST-01 harness to the wiring harness in the vehicle.
• If an ASWC-1 (sold separately) will be used, do not connect it until the GMOS-MOST-01 is
programmed and fully functional.
GMOS-MOST-01 programming:
Attention! If the interface loses power for any reason, the following steps will need to be
performed again.
• Turn the key (or push-to-start button) to the ignition position and wait until the radio comes on .
Note: If the radio doesn’t come on within 60 seconds, turn the key to the off position,
disconnect the interface, check all connections, reconnect the interface, then try again.
• Turn the key to the off position, then to the accessory position. Test all functions of the
installation for proper operation, before reassembling the dash.
ASWC-1 programming:
1. With the key still cycled on, plug the ASWC-1 in. The LED in the ASWC-1 will flash rapidly.
2. Tap the Volume Up button on the steering wheel at a heartbeat pace until the LED stop
flashing rapidly.
3. After approximately 2 seconds there will be a series of 7 Green flashes, some short, and
some long. The long flashes represent the wires that are connected to the ASWC-1.
4. The LED will pause for another 2 seconds, then flash Red up to (18) times depending on
which radio is connected to the ASWC-1. Refer to the L.E.D. feedback section for information.
5. This is the end of the auto detection stage. If the ASWC-1 detected the vehicle and the radio
successfully, the L.E.D. will light up solid.
6. Test the steering wheel controls for proper operation. Refer to ASWC-1 documents online for
customizing the buttons, if so desired.
