I'm hoping someone might have seen something similar and can offer advice.
Car was fine until Friday 20/01/2023 when I noticed that when I start the car the Honda Sat Nav / Audio start up splash screen was coming on, then would disappear after the splash screen and remain blank for maybe 30-35 seconds after which it loops back to the start screen. I've also noticed that the clock is wrong but there is no way to set it that I can find.
I've attached a picture showing the unit and the splash screen - I have tried disconnecting the battery for 4 hours (as suggested by another local owner) but it still does the same thing on re-connection.
Any help gratefully received.
