When you say the temp display is in the HUD, is that also the internal temp display as my HUD only shows the external temp display. Thx.You bet.
I drove a 2020 loaner, 2 of them actually. They both had the temp displays in the infotainment screens and HUDs. Maybe a master reset or Sync system reboot is necessary. I would definitely take to the dealer if those don't work. Maybe your APIM needs an update or replacement.
