F9220BT Lost Bluetooth Firmware

Recommended Posts

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.
