Google built in navigation 2025 Silverado 2500HD

Cannot enter a destination in the google maps address search bar and navigate to it. When I do, the vehicle location suddenly is nowhere near where I actually am, even though prior to entering navigation mode, my location on map display was spot on. Nearly always defaults to show my location at or within 1/4 mile of my home. I've used the map feature in the MyChevrolet app and the "send to vehicle navigation" function which does actually send the destination and navigation to the vehicle, and it will occasionally work for a little while, then suddenly it shows the vehicle location on the map display as off on side streets and the navigation directions become invalid. I've done the reboot, checked for updates. Nothing corrects it.
