Could someone enlighten me as to how the 2002 e320 telephone system works and the components. Although I don't see a cradle in the console, I see that there is wear on the steering wheel buttons , the "telephone" prompts in the display are operational (standby etc) which indicates to me this car had a telephone at one time. Could someone advise me on what parts/modules to look for and there location. And possibly how I might get a handsfree system working in this car somehow. And maybe a source for the parts I actually have a cradle from my 03 SL = I replaced it with the bluetooth puck. Im really curious the teleaid system was a cellphone was it not. I know all that stuff in that vintage became obsolete with digital. Is it two seperate systems ? Thank you in advance

Is there a diagram with locations of components

Thanks for the reply and my apologies for not reading the sticky thoroughly. I didn't find a diagram with component locations. That could be my oversight as well. I was hoping I wouldn't have to buy that expensive puck Someone is selling it for $599 on ebay now I have that on my 03 SL it works OK I'm not sure if any of the less expensive ones will work ie puck with tail I believe not.

The sticky has links to the phone bulletin for your car. I don't know what else you would need.

addl questions

Thanks Warren I see ads in ebay for Motorola telephone control module out of a 2002 e320 Is that the same as a PSE ? My car I believe had a telephone installed. I know this because the cables in the area where the cd changer/telephone equip was are not capped and tied or strapped - they are loose also the steering wheel control has lots of wear on the telephone answer hangup button. Other than that, I seem to hbave trouble locating the parts. One other question. Since I am planning on using a bluetooth puck is it even necessary to have the antenna linear compensator. As you undoubtebly know nwhen using bluetooth the telephones antenna is used. THANKS

The telephone control module would be the PSE. However, before you buy one from ebay, you need to look through the How-To Guide on cell phones, in the stickies in this forum. The answers to the rest of your questions are there. Slow down. Read it carefully, especially posts 1, 3 and 6 (you don't really have to read much else for your car). Your questions are showing that you are not reading what is there.

Hi again

Once again I am being admonished for not reading thoroughly. The ads in ebay I refer to do not match part number wise. I recall reading that the autosense pse is required for compatibility with modern feature phones So therefore my question re the motorola telephone control module is relevant - there is not a place in the posts that refer to the necessary component as that name. The telephone control module is not the same part as a PSE portable support electronic module Am I correct? The part number showed in one of the posts you referred to. heres my deal : I'm just trying to do this economically So so far a PSE @ $208 a cradle replace cable $? v60 puck $ 300- 600ou if you can even find one. Could run up to $1000 In my opinion not worth it. Are there any replacements for the mercedes B67875856 puck? someone suggested visseo pucks - will they work with the older d2b systems?

So without being sarcastic if you could find the time to just play along and answer my questions without a homework assignment I would appreciate it. Yes I am in a hurrry I have a way past full time job, Im not retired with unlimited time to research this and go through all of this information. And by the same token I am appreciative of the time individuals make on these forums so that guys like myself have a chance. And for the individuals who respond to the posts.

I understand "busy," but I do not have the time or inclination to coach each individual through the equipment necessary for each and every type, model, and year of car. That is why I wrote the Guide, especially the first seven posts, and provided the link to the phone bulletins that apply to each car. Because the "kits" are not available any more, I have provided individual part numbers for certain PSEs, and also the "blue label" information, such as it exists. Starting with no phone system at all, the best I can recommend for a PSE is the "Universal PSE" - you won't have to worry about the "Blue label" information. Believe it or not, researching just the first seven posts took weeks. There are limits my time as well.

No matter what an ebay seller labels it, if it is the correct part number for your car, the "Motorola telephone control module" is properly called a PSE - MB's term for it. However, be aware that the MHI system has an "MHI control module" - as MB describes it. I have no way of knowing what the device in the ebay listing is - a link to the ad may have helped.

As far as a substitute for the 5856 puck, the only one I have seen people say works is the BMW BTUM - but that is reported with mixed results. It does not always work. Because Peiker, which makes the V60 pucks, and whoever makes the BTUM (possibly Peiker) do not release details on the specific Bluetooth configurations of their pucks, I simply cannot tell.

The Viseeo pucks with which I am familiar are for the MHI phone systems and perform the functions of the 5878 and 6131 pucks. They won't work with your car.

If you are seriously interested in purchasing, and need further information specific to your car, I suggest contacting Keith Valentine (info in the first post). However, while he has been extraordinarily helpful to members of the forum, Keith is in the business of selling systems, not simply providing free installation advice.

Sorry about the "homework" assignments - but the information is already there (including the price of the Cradle Eliminator Cable). Except for the question about the Viseeo puck and a question about how an ebay seller described a part, all of the other questions you have asked are answered in the three posts to which I referred you.

appreciation

Thank you And I am grateful for your input. It is challenging to wade through all of the info on the posts you referred me to. I am however confused re the telephone module.
My take on the available "telephone modules" is that there are many versions and that the version you purchase install is critical to the correct operation of a modern smart phone. IE apple iphone 5 This phone works (not totally) in my 03 SL Just trying to get the E320 to the point where I dont need one of those hokey hands free devices.

Thanks for all of your efforts informing all of us It does not go unappreciated! Thanks

I am sure Keith helped you quite a bit. Unlike me, his business is selling and installing the equipment in the various Mercedes models, and he is familiar with the intricacies of each.

With regard to the telephone modules: The original StarTac PSE, the TimePort PSE, and the Autosense PSE will work with the V60 (5856) puck AS LONG AS they have the "Blue Label" as described in the writeup. To the best of my understanding, the "blue label" indicates that a firmware update was applied that allows them to work with the puck, and not be limited to plug-in phones. I suspect, without confirmation, that the update allowed them to accept the "handshake" from the puck that an MB-branded plug-in phone would have provided when connecting to the system (if the plug-ins were not MB branded, the phone system would turn itself off). The Bluetooth puck allowed non-MB branded Bluetooth phones to work with the system.

The difference a user will see among those three PSEs is that the StarTac would not display caller ID for an incoming call. The others do. However, I am not sure about whether all three would work with MB head units for which they were not designed - i.e., I am not certain that a TimePort PSE would always work with a car designed for an Autosense PSE. In my '00 I was able successfully replace the original StarTac PSE with a TimePort (to get caller ID), and it worked with the '00 COMAND unit - but that is hardly enough to draw a general conclusion.

As stock of the older PSEs were exhausted, MB came out with the "Universal PSE." It was designed to work in all the cars that would originally have had a StarTac, TimePort or Autosense PSE, and it was produced at a time when many states were requiring handsfree devices for cell phone use, and owners would wish to install Bluetooth in cars that never had a phone system.

To answer your question - a good one - the PSE used (except the StarTac PSE's inability to display caller ID) is not the limiting factor in compatibility with newer phones. The PSE essentially performs the integration and enables the control functions between the head unit and the steering wheel controls. With plug-in phones, it also connects to the car's external antenna. The limiting factor is the Bluetooth firmware and protocol stack loaded into the puck itself (information MB does not provide). That discussion can get a bit technical - one of the simpler, but relatively thorough discussions of it is at https://en.wikipedia.org/wiki/Bluetooth. Unfortunately, cell service providers frequently alter elements of the protocol stack to serve their own interests (e.g., Verizon is notorious for limiting or altering the stacks to force users to its "business partners" for certain services). When service providers do this, then the "Bluetooth standard" becomes pretty much non-standard. Fortunately, the basic Bluetooth core is supposed to be backward compatible, meaning that a newer phone should perform its basic functions with an older version of Bluetooth loaded into the car's equipment. But it does not ensure that you will get every function with every phone. That is why I say, test any phone you intend to buy with your car's system before you buy. Most full-service stores will have one that a representative can take to your car and test it for you.

I will say that iPhone 4 and 5 owners have reported success with the V60 puck. That's pretty recent technology - but for compatibility with the myriad other brands, you'll have to search the web, or try them yourself.

BTW - the discussion in the preceding paragraph applies to the pucks for MHI systems as well. The firmware suite in the 5878 and 6131 pucks is newer and is compatible with more phones than either the earlier MHI puck (5839) or the V60 puck discussed. Though their appearance is different, as far as I know the firmware of the 5878 and 6131 MHI pucks is the same. However, any system that uses a PSE instead of an MHI controller is limited to the V60 puck. In addition, the CP-211 system installed in certain models and only in certain years uses a "puck with tail" that has the same capabilities as the V60 puck discussed above.

Realizing also that Bluetooth overcomes the need for any kind of cradle, MB came out with the Cradle Eliminator Cable to connect the V60 puck to the system, instead of requiring owners to also buy a cradle. That was a good move, because the V60 puck dimensions fit the newer V60S cradles; it did not fit the older V60 cradles well, which caused some connection problems. The V60S phone was bigger than the older V60 phones because they had additional electronics in order to be E911 compliant (the function that allows phone locations to be triangulated from cell towers).

I'll repeat a note here: The V60 puck together with a cradle eliminator cable may resemble the "puck with tail" used with the CP-211, but the connectors to the console are entirely different.

All that is history, and it is scattered throughout this lengthy thread, making it hard to put together. It won't help you install the equipment in your car, but perhaps it will help to understand some of the complexities.

One thing (mentioned in the first post, but worth repeating) - if you are installing an MB phone system in a car that never had one, version coding is required so that you get full functionality of the system. If you are replacing a system in a car that had a phone system, version coding was done at the time of the original installation, and is not necessary.

Hello again Warren. Apologies on bothering you in any way! I mean no disrespect to your time and /or kindness in helping me out several times. In the thread above, you mentioned 3 different PSE telephone modules. The Star tac, the time port, and the autosence PSE components. How do I know which one I have> On my 02 S500.?? I had to replace all the components earlier this last year, as I explained in another thread to you earlier this evening. So can this be that cause of not getting any sound from in or out going calls from my phone, even though the blue light on the center console puck is lit up all the time, and it says on my phone that it IS indeed connected to the MB SYSTEM through the bluetooth connection. But on the dash, it says no PHONR CONNECTED< and no sound or interruption to the radio when a call is coming in or out...
Any direction would be amazing1
Thank you again, Truly!

Oh, also, would it need to be re coded if I replaced all the components? Everything else is working just fine, all other components, its just the phone bluetooth.

The way to tell what you have is to check the part numbers on the PSE that is installed. The StarTac PSE has part numbers Q 682 0460 or 9460, SYN 0234 A or B; the TimePort PSE has Q 682 0648 or 9648 (I don't know its SYN); and an Autosense has numbers Q 682 0754, SYN 9266A or B. The straight V60 PSE had numbers Q 682 0845, or 0886, SYN 9266B. The "Q" numbers may also show "BQ" (BQ 682 etc.)

If you have a StarTac or Timeport PSE that does not have upgraded firmware (the "Blue Label" PSE discussed in the How-To Guide) necessary to support Bluetooth pucks, you will have to replace your PSE with either the “Autosense” version or with a new "Universal PSE," PN Q682 0971 ($208). If you have an Autosense PSE (Q 682 0754, SYN 9266A or B) you may continue to use it.

You should not have to re-program (re-version code) your COMAND. Per your discussion at post 745 in the How-To Guide, your system is already version coded.
