Basic Operation

Activating Your SIRIUS Subscription

You must activate SIRGM1C before you can start to receive the SIRIUS Satellite Radio broadcast.

1. Make sure that the SIRGM1C is properly connected and that its antenna is oriented to receive the SIRIUS satellite signal.

2. Turn on the headunit.

3. Use your factory radio’s controls to select satellite radio as the source. Pressing the BAND button will change sources to SR1 or SR2. Note- some headunits will display XM1 or XM2 when in SIRIUS mode.

4. If this is the first time the unit is connected and receiving satellite signal, the display may read “UPDATING” until the SIRGM1C channel update is completed. This is where the latest channel line up is updated on the SIRIUS Receiver.

NOTE: Don’t push any buttons or perform any operations until updating has been completed. Once updated and the SIRIUS channels are received, you will be tuned to SIRIUS Satellite Radio’s Preview Channel (Channel 184). You should be able to hear the SIRIUS Preview channel’s Audio.

5. Find the SIRIUS ID (SID) of your unit. The SID can be found on a sticker on the bottom of the SIRGM1C or by tuning to channel 255. Press the display button (DISP on most units- some use INFO) to select either artist name or song title. Both fields will display the 12-digit SID.

6. Write down the 12 digit SID in the location provided on the next page for future reference.

Note: You will not be able to tune to any other channels until you activate your SIRIUS subscription.

After the unit is activated please follow the steps below to insure proper operation of the unit:

1. Power off the headunit, close all doors for 1 minute.

2. Open the door and either start the car or turn on the ACC.

3. Cycle through the BANDS to select SR1 (or XM1).

4. Select each preset one time (the headunit may have retained presets from the XM radio. This will change all the presets to the SIRIUS default channels.

5. Press BAND to select SR2 (or XM2) and repeat step 4 above.

6. You can now tune and set up your presets as you wish.

For specific headunit functions, please consult your GM headunit owner’s manual for proper operation instructions for using satellite radio products.

Note: When reactivating a “deactivated” receiver, the headunit MAY show the UPDATING message continuously. Channel tune UP or Down to clear the message.
