JVC KW-V850BT Factory Reset

[MichaaeelMk1]

Hi all,

My jvc kw-v850bt head unit recently gave a "there is an error in the speaker wiring. Please check the connections. 3655" error.

I am certain that that is not the issue as I've had my head unit installed by professionals and have taken it to them to be checked over. I was told that a reset would do the trick.

The head unit does not have a reset button and I cannot find any leads on how to reset the head unit. The head unit only has 3 buttons - volume up, volume down and fnc button.

Any leads would be appreciated on how to reset this deck.

Thank you
