A factory reset might be required to clear any software issues. Have you spoke to your dealer?
The hud setting is one of the additional settings saved with the seat position. Might want to check that.
Other settings are saved as well:
"Driving Position Memory System is the facility that enables driver's seat, steering wheel, exterior mirrors, clus- ter and head-up display (HUD) to be controlled with a simple button oper- ation, which allows a driver to recall memorized driving positions and automatically control them. Driver's seat/ Steering Wheel/ Exterior mir- rors: location Cluster: Brightness of lighting
Head up Display (HUD): height, rota- tion and brightness."
This happened to me a couple of times, glad to see there's a quick solution. Thanks for the tip Wilson!Stinger owners went through the same thing. See this quote:
