MBUSA Acknowledges Phone Problems
"Poor Hands-Free Quality When Using Voice Control System in Model Year 2003 and 2004 W211 Models--
If you receive customer reports in the above model vehicles of poor hands-free quality during a phone call using the voice control system unit installed, do not change any parts at this time. Typical symptoms include echoing, high pitched chirping noises, and general distortion of the voice to the point where the speaker is incomprehensible. Currently, a solution is under investigation, and will be released when available."
While this does little to address the problems I (and others) have been having with the phone system, I will take solace (for now) in the hope that a solution is forthcoming.
Now I know for sure not to bring my car and have the dealership look at it.
I hate leaving my car at the dealership.
