I’m looking for a way to add integrated SiriusXM to my 2021 Trailblazer LS. The dealer told me the vehicle had it, but I neglected to verify that before buying. They tell me now that GM has no option to add it, and is getting away from sxm support because CarPlay can provide it. (Though that’s buggy and so resource intensive.) The OEM and third party products I’ve found are not compatible with this particular Infotainment system (7” with wireless CarPlay). Does anyone more familiar with the electronics have any ideas? Thanks.
