wow, this is new info, thanks.

As it is now, I have a Nokia 6100 series phone holder bolted to the right of the console at the level of the radio. The microphone is the from the Nokia kit and it is attached to the left of the driver's sun visor. The sound for the phone comes from a Nokia speaker that is mounted deep under the dash above the passenger's feet. Antenna on the rear window.

This reminds me of some curiousities I had before of how the phone is wired and where the Nokia controller box is placed. With the way MB's are about the stock sound systems, tweeters in there would mean lots of custom work and maybe no-work.

How are the factory installed phones installed and where are the phones placed?

Thanks for this news.
