Hello -

I trying to get into the center display's diagnostic mode to adjust the backup camera guidelines on my 2018 Fit EX-L (no Navi). All the searches I've found refer to pressing Home-Eject-Power but my unit does not have a CD player/Eject button. Another search result said to press Brightness(Day/Night)-Menu-Power(Vol), which seems to have no effect. Brightness-Home-Power reboots the unit it seems. Other combinations don't appear to have the desired effect. I would appreciate a clue.

 

Did you figure this out?

 

Interested as well.

 

In case anyone else is looking, I have a 2018 EX w/sensing and I was able to get into diagnostics using the Brightness(Day/Night)-Menu-Power(Vol) combination. I'm confused about whether my car has Navi. I definitely don't have Honda's "Satellite-Linked Navigation System", but when I got into the diagnostics system one of the two main options was something like "Auto Diagnostics - have Navi scan entire system for errors". It seems like the computer system is still called Navi even when you don't have Honda's navigation system. I also saw references to satellites, etc. In the diagnostics menus.

I think I pressed and held Brightness (day night) first and then quickly pressed and held menu and power at the same time. Not sure if that made any difference since it worked on my first try.

Edit: I just had an issue where the combination described above just restarted the computer a few times instead of going into diagnostics. I had the door open and then I got it to work with the door closed. So maybe you can't get into diagnostics with the door open.
