Hi John
It's becoming a murder mystery tour this episode! Incidently, my instruction manual made no mention of mp3 capabilities.
I saw the chap try and insert the latest upgrade disk, the updated version of W211 589 06 22 00, and to quote the him 'it was having none of it'.
Realistically, I am not sure how to proceed, other than to ask another dealer to perhaps try in a several months when the car is next due a service.
P.S. I really appreciate all your input.
Good morning Harvey,
I feel for you and understand your predicament. Our vehicles come with so many options it is extremely difficult for main dealers to keep abreast of technical features (I would of thought impossible for independants\specialists).
Having read your previous post, I had my doubts about what I believed, so before replying I contacted someone that quite literally travels the World fitting this equipment, plus everyone holds him in very high regard. He confirmed my suspicions and you are being fed false information by the dealer.
The most important issue is to maintain a good relationship with the garage and if I were you

. I would go back to the dealer, thank him for trying to upgrade your COMAND and then suggest they contact Mercedes-Benz UK and ask for more expert technical support. As I have repeatedly said, our COMAND was manufactured in those first early months of release and we now have the capability of playing Mp3's. It needed the upgrade and it must be installed correctly. I would be wrong to outline the full procedure, but if they simply plonk the upgrade into the drive, install the software and expect it to work, then they are not doing it right!
Regarding the COMAND manual, there is no mention of Mp3 capability in mine, so do not let them use that as an excuse.
I fully understand if you want to let this matter drop, as it must be frustrating, especially when the so called experts are saying you cannot do it, and an unknown forum member says you can.
Good luck with the decision,
John
