Same here, half the roads in town don’t show speed limits. And the other half are often outdated / inaccurate. Not a great feature but I do leave it displayed in HUD because something has to fill that space.
There isn’t any functional difference between the GMC and Chevy uplevel clusters. But because you cannot get that cluster without nav, I’m curious if the speed limit sign is just permanently there and empty on the home screen if the truck has IOR or IOS (non-upgraded to IOT) infotainment.
With the midlevel (small screen) cluster, navigation trucks get do get the speed limit signs and nav page. But non-nav trucks don’t have the empty sign sitting there all the time because there are two different cluster “display modes”, if you will, depending upon the infotainment installed.
If the uplevel cluster doesn’t have a “display mode” for a non-nav truck, presumably those upgrading to this cluster will be stuck looking at empty speed limit signs on the home page unless they have IOT or an upgraded IOS system?
