Although I got a 3 year subscription to OnStar with my purchase, settings in the heads up display change. Namely Google Maps require an OnStar subscription and have an option to give the speed limit for the area you are in on the heads up display. Twice now that feature goes missing and I’ve had to call OnStar to do a reboot.. Other settings have changed as well for the vehicle like all of a sudden the seat vibrates for an alarm notice even though I’ve opted for beeps instead!! Quite a shock to the gonads when not expecting it! Anybody else notice their settings change randomly?
