With AM radio, you can enjoy a wider variety of stations featuring news, talk shows, sports commentary, native language programing, automated traffic guidance, and emergency broadcasts. AM waves travel further and penetrate buildings and obstacles more effectively than FM signals, especially at night. Having both FM and AM stereo radios the Hummer EV SUV offers a more comprehensive listening experience compared to only FM in the EQB.

HD Radio boasts several benefits over conventional radio: superior sound quality with clearer and consistent FM broadcasts, CD-quality audio, and Multicast Channels offering up to four streams from a single station, adding programming choices. Cars like the Hummer EV SUV equipped with available HD Radio provide an improved in-car entertainment experience. The EQB, devoid of this technology, foregoes these benefits. Selecting the GMC Hummer EV SUV empowers drivers to enjoy a more immersive and enjoyable listening experience while on the go.
