Yesterday I spoke to Elke, extention 225, in customer service at www.wireless4mb.com and she informed me that my issue is extremely common and she hears the same complaints all the time.

She said the issue is inherent with blue tooth technology and that there is no solution other than going with a hard wired (non blue tooth phone connection) that makes use of the car's antenna and hardware.

I find it odd that on this forum and others I read that people are very satisfied with the operation of their blue tooth phones.

For the record, I can hear perfectly on my end with the call coming through the car's speakers. If not for the fact that the people I talk to on the other end were complaining, I would not otherwise know there is a problem.

Please respond if you have had better experience with your blue tooth connection. I am about ready to bag the experiment and go with a hard wired phone.

I wanted to avoid having two phones, two phone numbers, etc., but if the blue tooth sound quality has not been perfected yet, alas its not worth having sub-par phone conversations particularly when I am talking to clients from my car.
First of all you need to understand that you are not even using true bluetooth.
Bluetooth is a wireless system, not an adapter to an existing analog or digital system like the connections are in the MB cars, therefore not true.
So my guess is since you convert the bluetooth signal to be played through the car's circuitry, you have to suffer some signal quality loss through the audio stream conversion which goes something like this:
Analog Microphone to Digital or Analog?( the car's system ) to Bluetooth ( the adapter mated your handset ).
I have found another little irritating thing about these adapters. if I am within 30 feet of my car and someone calls me, my command automatically turns on and answers the phone. Of course i can no longer hear them on my handset because their voice is coming through my car speakers which I am not in. The same thing happens if I am on the phone in the car and reach my destination. When I shut of my car the car's system remains active till I end the call or manually disconnect the bluetooth which usually hangs up my call.

My phone sounds great in my 07 Audi because the CAR is bluetooth. No adapters. When I turn off the car if I am on a call, it automatically switches to my handset. Also if I am on a call and I get in my car the system will automatically assume management of the call.It's so seamless, that that caller never knows that I have entered or exited my car. That's Bluetooth!!

I have to conclude this sermon by at least giving credit where it's deserved.
3 years ago, using my PeBL or whichever Motorola phone of my own choosing with my mercedes was completely out of the question. At least now I can use the damn thing, and my phonebook loads automatically with no problems. This creature comfort only cost me 300 and change which is a fraction of what it used to be with many many limitations not too long ago.
So if all I have to do is remember to unplug that stupid adapter when I get out of my car, and remember to plug it back in when I re-enter, for what it's worth, I'll take it.
Maybe it 07 or 08 or 09, MB cars will have waken up and integrated "true" Bluetooth as part of the car's system so to eliminate the need for plug-ins.
