  1. F9220BT Lost Bluetooth Firmware

    Hi guys and gals, I too have the missing BT-firmware problem ever since I bought the car second hand. I updated my unit (F920BT!!) from the 2010 to the 2015 maps version and then tried to update my bluetooth firmware aswell. It showed a message that the update would take several minutes etc. but after a few minutes gave up: "an error occured and the BT firmware could not be updated". Could it be that it can not update because there is no original firmware to be found ("Version: ----------- ") ? If so 1 were do I get my hands on the original 2010 version of that file? 2 what file am I looking for? Any suggestions are welcome as I am running out of ideas here.
