Hi,
I did 12v battery maintanance.. Leaf was giving me all sorts of errors that are now fixed. But I think the AV / Navigation unit went crazy while I tried to figure what is wrong during low 12v battery situation taht I had no clue of. (I had Airbag, Brake, PS leds all up and no Lithium battery connection and only 12v, with all attempts to start normally, as symptoms on display.)
So now the 12v is ok, I get no warning leds on dashboard and Lithium main battery connects fine and driveing is possible.
But the AV / Navigation unit is in FM mode, the buttons (multifunction switch) beside 7'' AV/Nav screen dont work at all.
Nothing happens If I push any of them (Menu/Seek/Vloume etc.). The below AC/Climate buttons work perfectly. In nightmode the m.f. switch buttons have night lights working tho, but clicking makes nothing happen even then.
So I have tried to disconnect 12v neutral again and wait.
ON, then OFF. Waited 1 minute, disconnected 12v, waited 3min, reconnected. AV/Nav side buttons aka m.f. switch buttons still dont work.
AV/Nav screen is still stuck on FM radio mode.. touch screen still works, but no way to change mode. Wheel volume buttons work, but no sound via FM radio as before.
So I have tried to disconnect AV/Nav unit power.
In front of battery I saw a fuse box, inside the lid case I found "AUIDO" fuse, its with "20" mark first in row of similar tiny fuses.
I pull this fuse out. I start Leaf - everything starts but not the 7'' LCD screen, so AV/Nav indeed was unpowered.
I put the fuse back. I start Leaf again - still same situation.. 7'' LCD stuck in FM radio mode and sidebuttons not working.
There I found manuals:
https://carmanuals2.com/brand/nissan/leaf-2013-373
I checked "Audio Visual System (Section AV)" manual
I try searching reboot/reset/defaults, but find nothing useful.
Page AV-345 .. I found...
But I have no idea what to do with those connection numbers.. like where are they?
So how to properly factory reset or soft reboot the damn AV/Nav thing to get it unstuck, I want my buttons working again.
