I just got a Bluetooth adapter A67875878 for my S550. I paid $125 included shipping. Now I don't have to paid over $300 to get the A67876131. It paired with my Motorola Driod beautiful, very easy, no problem. The contact book transfered very smooth.

Does anyone know where to get this A67875878 adaptor? A google search does not come up with anything other than this thread. I am looking for an adaptor for a 2005 S500. The adaptor I have has horrible sound quality according to anyone I call.

The BT adapter B67875878 does not work on W220 only W221 with MHI and BT puck pre-wired. Your 05 S500 is W220. You need to wire the BT module or use a V60 adapter.

Thanks for the heads up. I have (I think) the same car as you and my bluetooth module has horrible reception. I have the v60 cradle and an old v60 and got the module about a year ago. Do you know of any modifications or firmware updates or changes I can make to the head unit to improve the bluetooth?

Any info is much appreciated.

This information is incorrect, MHI phone systems started in 2005 in all Mercedes minus maybach/SLR check your center console to see if you have a phone kit installed if so you just need the 6-7-87-5878 or 6-7-87-6131

My original post may have been unclear. I have the adaptor, but it seriously lacks for clarity. I was hoping someone else had a better adaptor, or knew of an upgrade to the firmware or a change in setting that might help.

There are firmware updates for the older bluetooth modules, but I don't think they address clarity issues. Which person is having the distortion is it the calls coming in or the person on the other end saying you sound bad? If you are using a cradled handset like I think you are saying then it sounds like you have bad hardware in the loop.

I must not be communicating this very well. Sorry. I have the bluetooth module (I took the v-60 cradle off) and now have a lot of people telling me the sound is awful. I was hoping someone had either a firmware update for the bluetooth module or for the phone.

To answer the question, people tell me I sound like I am on a soup can and string. I can hear them fine; they cannot hear me. Any help is greatly appreciated.

It sounds like an issue with the microphone, you should take it in and have it checked and replaced/recalibrated.

I think I am down to that as my last resort. Any idea what the cost is?

If the mic is bad, it's not cheap. IIRC the mic is integrated with the complete mirror.
