Hello all!

Yesterday i wanted to change the headunit of my Civic X 2018.
I dismantled the slot, removed the original headunit and replaced it with this one

Everything worked, I start to enter the canbus settings but I realise I forgot to put the frame in. I unplug everything, put the frame on, and plug the new headunit back in. But it doesn't light up anymore!
In doubt, I reconnect the original headunit to see if the problem comes from the new one, but the old one doesn't light up at all either!
I checked the cables, none of them were damaged, I didn't pull hard (it could have disconnected a cable).

Everything else in the car works fine, but I can't get the sheadunit to work, old or new.

Do you have any idea where the problem could be?
I checked the fuse but i'm not sure to find the good one. I used this site to find the related fuse but my car doesnt seem to be very identical : 2016 Honda Civic fuse box diagram - StartMyCar

Thanks for your help!

Check “back up” fuse 18

I change with a new one fuse 18 but nothing changed

There may be an additional fuse, check the owners manual

Yes thank you I struggle to find which one it is.
