Hubby’s truck 2020 Sierra Denali purchased in May. On Nov 27 a speed limit sign began to appear just above the tachometer. This is NOT the HUD or the speed indicator that can be turned on and off. Issue is this is working inconsistently; it will work on main and secondary roads, not on residential; that seems logical. BUT going residential >secondary>main, it won’t show until the third turn. Any idea where we can find specs on how it should operate? Dealer didn’t know anything about this feature being pushed out or how it should work.
Thanks!
Thanks!
