For 2020 Silverado 1500, Silverado 2500HD/3500HD, Traverse, Acadia, Sierra 1500, Sierra 2500HD/3500HD, XT4, XT5, and XT6 models equipped with Infotainment 3 systems (RPO IOR, IOS, IOT, IOU), technicians may no longer find the SiriusXM (SXM) Radio ID on channel 0 (zero). The SXM Radio ID will be needed, for example, if there are missing SXM channels or no audio on certain SXM channels and it’s necessary to verify channel status with SXM.
To view the SXM Radio ID on certain 2020 Infotainment 3 systems that do not display channel 0, tune in the SXM band and then select Settings on the right side of the screen below Browse. Next, select Manage under System Settings to view the Radio ID.
SXM Service
The SXM digital radio signal is broadcast from two satellites and, where necessary, terrestrial repeaters receive the satellite signal and re-broadcast them at much higher power levels in order to ensure reception in areas with densely packed tall buildings. Keep in mind that even with repeaters the signal can be compromised, resulting in loss of the SXM signal.
In addition, some channels may be moved or deleted by SXM, may be package specific, or are listed as Online listening only.
Here’s a look at finding the ID on an Infotainment 3 system. (Fig. 15)
