Hi everyone,

I bought used octavia 2021 mk4, In my country they do not come with navigation activated, so I paid a 3rd party to activate navigation.

It was working great but I wanted to update navigation database because it had version 21, from official skoda site downloaded the latest version, (2023 version was avaivable as far as I remember).

Navigation database was updated after 2 or 3 days after I left my usb stick on the car usb port. After that I unpluged the usb stick. Navigation was working fine for 2-3 months after I unplug the usb drive.

Sometimes navigation won't open but after I reset the multimedia or on the next trip it was working fine.

One day navigation stopped working, It says "navigation loading" on the screen constantly, when I checked the navigation database version, It was blank. So I went to the 3rd party that activated my navigation.

He couldn't fix it, tried to install base navigation database from some forum, (I guess from here).

I already long pressed the shut down button, tried to install base navigation version, tried to update firmware, nothing works, I also can't update firmware.

Release version: MOI3_EU_SK_R7880L software version: 1788

From obd11 device I get no navigation database error, after I updated the database I get navigation database malfunctioning error "B126CF0"

I guess if I could format the navigation database it will sort out but I don't know how..

Cheers..

Firmware you have To Update in the Service Menü

@carius I will try formatting if I could format only navigation database not something else via odb11. Do you know how safe it is? I already do not have warranty on my car.

I used service menu, enter red engineering menu by long pressing menu button, car recognised the firmware but always it took 2-3 minutes for about 9 gb update,

After reboot it says update successfull but after update, firmware version do not change.. maybe I need to open the hood while updating, but I don't mind old firmware version.

Just want to see navigation system working again.
