Re: Replacing battery on Feruno Navnet 2
the battery for the MFDBB (Navent 3d Black Box) is a CR 3032 but you don't have to change it since it has no use
Here the feedback from Furono support:
That is a common button cell battery and is not really used in the Kontron processor. Most remove the battery and put the bios setting not to check for the battery.
I have one in spare but never changed it.
