did you try battery reset for couple of minutes ?
RE: HU_ENTRYNAV after coding with BU down - kampftux - 05-05-2025
Yes for 5 minutes, no change.
Will leave them disconnected overnight. Hope that will help.

I doubt it will make any difference , 5 minutes is more than enough .

After a night without power, the HU started again this morning. It was coded with BU again, and everything is fine
