• Connect the RCA jacks to the audio AUX-IN jacks (if applicable).
Note:
(a) This will allow you to retain the 3.5 AUX-IN jack in the console.
(b) The 3.5 jack can only be used if it is a single AUX-IN jack.
(c) If the AUX-IN jack has a USB port, neither can be used.
12-pin pre-wired ASWC-1 harness:
• This harness is to be used along with the optional ASWC-1 (not included) to
retain steering wheel audio controls. If the ASWC-1 is not being used, disregard
this harness. If it will be used, please refer to the ASWC-1 instructions for radio
connections and programming.
Note:
Disregard the harness that comes with the ASWC-1.
• Connect the
Red
wire to the accessory wire.
Note:
The relay attached to the GMOS-044 is only for audible turn signal clicks.
No extra steps are required to retain this, so leave it as-is.
With the key in the off position:
• Connect the GMOS-044 harness into the interface, and then into the vehicle.
Attention!
If the interface loses power for any reason, the following steps will need
to be performed again. Also, if installing an ASWC-1 connect it after you initialize
and test the interface/radio, with the key in the off position.
• Turn the key (or push-to-start button) to the ignition position and wait until the
radio comes on.
Note:
If the radio does not come on within 60 seconds, turn the key to the
off position, disconnect the interface, check all connections, reconnect the
interface, and then try again.
• Turn the key to the off position, and then to the accessory position. Test all
functions of the installation for proper operation, before reassembling the dash.
