Interesting. So was this even after you swapped in the new Antenna? My nav is showing the same issues, and the OCD in me wants to get it working even if I don't use it.

Nav system is fully functional again.

FWIW, it’s evidently common to have the car revert to “Transport Mode” after a battery failure. It’s often accompanied by the Air Conditioning to also stop working in that mode.
