I have a 2004 E320 where I retrofit a bluetooth-puck-with-tail. When I talk to people they always complain that there is lot of noise in the background...and that my volume is low.

I am trying to establish where the location of SOS microphone is (used by puck). Is there a way to add a microphone? or to replace existing with a better mic (maybe unidirectional one)?

pictures will help.

In rearview mirror.

thanks MB211. Is this mic upgradable? Do you know?

Can someone give me step by step directions on installing the puck with tail on a w211 2004.

Step 1: get puck with tail
Step 2: undo 4 screws in armrest - top part - remove faux floor
Step 3: plug in puck to the only available harness neatly tied in there
Step 4: put floor back (you may have to pop a round pre-cut area in front to allow for wire
Step 5: go to dealer and have your car version coded for telephone attached.
(yes I said telephone and not bluetooth - thats soemthing totally different in MB world . BT puck poses to be a motorola phone cradle for SOS device).

Personal note: Its okaaaay. since SOS is for emergencies only, mic is really crappy. lots of background noise and low mic volume. I have always had ppl complain. BUT worth the effort in my opinion.

ya, the 03 - 04 ones had 4 mics in the rearview mirror that were pretty crappy from what I've heard, but I've heard that the 05+ ones come with 3 mics that are better, but not sure

Anyone knows how to add a mic? I read a thread years ago about someone replacing mics but cannot find it anymore.

Newer (07+) have a better mic set in top of rear view mirror. Previous model has mics in bottom of mirror. I do agree they could be better......

Okay so I did the first 4 steps, but not the 5th.

Phone works, but with some background noise.
Have not updated the COMAND software since factory (2004 model year)

What will step # 5 do, if anything....?

mobinakhtar

Nothing - your car is already version-coded if phone works. Mine was not version coded from factory so I had to go to dealer - on the other hand, my friends puck worked out of the box without version coding.

I have an '06 W211 with Nav and P2. I think it's pre-wired for phone as there is a "Phone" option within the Nav/Command screen. How can I determine if I just need a Bluetooth puck, is there a place I can physically check for this connector? And if that's all I will need, what part number would I be looking for?

Was looking into this unit, http://www.incartronics.com/MBMost.h...&VIM=1#itronic, but I'm not sure if that's exactly what I need to enable Bluetooth on my car.

Thanks much.

Look in the glovebox, under the "floor".

It should plug right in and the set-up/progamming was easy.

First I used a V3 Razor phone, nowadays a 3GS iphone.

The system works fairly well, but crappy microphone, or so I have been told.

Never been on the receiving end of a phone call, but have heard the connection is pretty good when the car is not moving, driving at the freeway I get complaints of back ground noise, possible tire/road noise.
Was hoping my new tires would cure some of the problems, but the Potenzas are pretty noisy as well...

I know this is an old thread but I'm wondering if there's a chance that my 2005 which was built in 2004 has the connector needed to install the bluetooth puck with a tail. Is there any way to tell without taking the center console apart? Thanks!

Not really - you have to take the felt bottom off and you can instantly tell. Its not hard and chances of you destroying anything are slim. Just do it.
