truckrglenn, do you still have a 2017? If yes, I don't think it will work, this unit you purchased from Xi Jinping is for the new 2019+ infotainment, and our cars no longer get official map updates anyway (see screenshot below).

My 2023 map update came on a USB stick, had my VIN in the manifest already (with some checksum protection), the file structure was different and the infotainment version was 2.5 or something similar, not the 3.6 I see in your post.

Also, even if this is a legit update, while GM could've made them backward compatible, I would be very, very surprised if they actually gave a **** about us owners and made it so.

Is the 2019 map update compatible with 2018 cars? My maps are just old these days... If not, is there another method to get the most recent 2018 update?
