If you run across a 2021 Toyota Highlander or Venza and you experience the situation below then 1) try unplugging the Navigation ECU and rechecking 2) try the navigation reset with key on and in reverse for 15 minutes, if still no change then you may want to look towards the Integration module sub-assembly underneath the center console as the cause.

Toyota issued Tech Tip t-tt-0662-21 about diagnosing this issue.
