HD Radio

[Byrds8]

I just purchased a 2021 Sierra SLT this past Thursday. On the screen, it has the HD Radio button. However, when I press it, all audio goes away. It looks like it is still receiving signal but no audio. If I hit the button again, audio comes back. Any clue on why this would be or what I am doing wrong? I know some trucks didnt come with it but I would assume mine did if the button is there.

HD radio on mine is different or additional channels. I used to have only one 106.5.  But now I have 3. The original one plus two new HD ones. Try scanning through the channels to find a HD station.

How do you tell the difference? I tried to look up on the internet and see if there were any HD stations in my area and it lists a good many. Granted, when I told my radio to browse, it didnt find any that are supposed to be in this area. Could it be the software is there as if it has an HD radio but there really isnt one installed?

the 2020 and the 2019 Silverado's have different radio's, the 2020 comes with the 360xl Sirius XM and my 2019 just has a plain SIRIUS XM hd radio, put it will pickup AM and FM  HD channels, just scan in your local area.

They advertise the "LOADED" with features in the 2026 Denali Ultimate and even tell you that it has HD radio along with all the other features a person would want when you buy it!  Massaging seats, stereo in the tailgate, among others BUT,  HA HA the radio works part time ( they are working on the issue) and no HD in it, (chips cost to much or something), and one other thing missing, a cigarette lighter. What do you want from a Pickup that costs just under ONE HUNRED THOUSAND DOLLARS.
