Effective immediately, the HD Radio (RPO code U2L) will no longer be available in the 2021 Chevy Silverado LT, RST and LT Trail Boss trim levels. As of July 12th, the HD Radio will no longer come in the Silverado 1500 LTZ and High Country, either.
Similarly, the HD Radio has also been removed from the 2021 GMC Sierra 1500 SLE and Elevation trims, effective immediately. The Sierra 1500 SLT AT4 and Denali will remove the HD Radio as of July 12th, as well.
For the Chevy Silverado 1500, the HD Radio is offered as part of the Convenience Package II (RPO code PCM) in the LT, RST and LT Trailboss trim levels and comes standard in the LTZ and High Country. The HD Radio is part of the Preferred Package (RPO code PDQ) for the GMC Sierra 1500 in the SLE and Elevation trim levels and is standard in the SLT, AT4 and Denali.
In addition, all 2022 model year Chevy Silverado HD and GMC Sierra HD trucks will be shipped without the provisions required for the HD Radio option. This is also being done in order to cut back on microchip usage in certain pickup truck models.
Trucks affected by this change will feature a Monroney label (or window sticker) with RPO code RG0 displayed, which signifies that no HD Radio was installed on the vehicle. A $50 credit is also being applied to the Manufacturer’s Suggested Retail Price (MSRP) for these affected trucks.
GM said previously it would build certain Chevy Silverado and GMC Sierra trucks without Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) technologies due to the ongoing global microchip shortage. Like the HD Radio change, trucks affected by the AFM/DFM deletion are also offered with a small $50 credit.
By cutting certain technologies out of its full-size trucks, GM can help maintain adequate production output of the hugely popular vehicles even amid the ongoing microchip supply shortage. While GM expects the effects of the chip shortage to wain in the second half of 2021, chips are likely to remain in short supply into 2022.
