Bluetooth for R-class?
If I understand the details correctly, you need to have purchased the Integrated Hands Free Communication System as part of your factory COMMAND installation. I actually asked your question to my own service department because I'm also interested in this feature.
If/When I know more, I'll pass it along. Maybe someone else has already found the complete answer.

I looked into it and decided that this will have to suffice:

I have a 2006 R500, and for this particular model there is a "completer kit" for cars that were manufactured without the wireless system (do not confuse this with tele-aid, they are distinct systems). I got a couple of different part numbers for the kit, I guess MB is changing the numbering scheme or something:
Completer Kit for R500 (and maybe others):
Q.6.82.0965
also check BQ 682 0962
approximate retail for this is $625 USD
Core kit for R500 (may not be needed if you have certain accessories already installed):
Q.6.82.0962
approximate retail for this is $450 USD
Bluetooth Adapter (I think this is also available from AWS):
6.7.87.5839
approximate MB retail for this is $350
There is also a Star Bulletin on this upgrade. See T-82-70-454A.
Note that the MOST ring configuration must be modified, which can only be done with a Star Diagnosis computer. The Star Bulletin indicates that installing this may void the factory warranty, so consider having a dealer install it for you. I don't know the official installation time, but I would guess they would bill this at 2 hours or so.
Net net, this probably costs about $1000. Certainly that's nothing to joke about. But I think the solution is much more comprehensive than dashboard- or visor-mounted solutions, particularly when you consider that many phonebook and other phone functions will work with the MB dashboard and steering wheel controls. It's got my vote.
