Miller: "Thankfully you won't need a hardware upgrade but there are software updates and there's obviously a map update. So this LIDAR based map was one of our key advanced technologies that went into Super Cruise. And this map is stored in the vehicle so for these new '23 vehicles, including the Tahoe, the Suburban, the Escalade and Yukon, we started building those with the correct software and map so that these customers can start utilizing these roads immediately and these vehicles should start hitting dealership lots here in November.

You will need a software update which will come over the air." For more information on these and other vehicles, check out CarPro.com. With Today’s Auto News, I’m Laura Reynolds.
