Firmware upgrade for Audio 20

[rp83]

hello -

still new to Merc world so would appreciate any help. I gather upgrading Audio 20 firmware may allow audio streaming for my 12 plate E220.

I was wondering if this is something can be done by downloading the firmware and loading it via cd/dvd or does it need an expert to do so? is firmware free to download? Note, I am not looking to update the maps, just firmware for the audio.

any help is appreciated.

There isn't anything downloadable or that can be purchased independently; dealer only I believe….even if you find an independent specialist who could do it, the problem comes when you book the car into a dealer, because the update isn't on their system, whatever they do may create a conflict or issue…e.g. maps being lost, for example.
