You do not need anything. Just run thru the settings on the dash and you can select to show the speed limits.Do the 23 models need OnStar for the active speed limit signs to show up?
My 23 Suburban seems to have stopped showing the speed limit. Seems to coincide with my initial free trial of OnStar ending.
My 2021 Yukon has the SD card.
