UHI and MHI Razr Cradle with Integrated BT Questions
1. Will the European UHI MB Razr Cradle (MB P/N B6 787 5868) access the SIM card on a non-SAP phone when the phone is docked in the cradle? I assume the BT feature in this cradle will not work with a non-BT-SAP phone, like the Razr V3 or Razr V3m.
Separately, it seems odd to me that MB would sell a BT-SAP cradle for the Razr, when no SAP compliant Razr exists. Or have I missed something here?
2. Will the same UHI Razr Cradle work with a CDMA phone when the phone is docked? Should I expect any issues with phonebooks? Will it be possible to make and receive calls?
3. Alternately, will the European UHI HFP Adapter (MB P/N B6 787 58 77) make use of the car’s external antenna and compensators, while using the HF profile? Does it have any issues pairing and working with BT - HFP equipped CDMA and GSM phones?
4. Finally, will the US-MHI Razr Cradle (MB P/N B6 787 5869), which I understand to be BT-HFP only, work in a European UHI car?
Application is a European spec W211 with Euro code 386 UHI phone system installed, and with Euro COMAND-APS, operating in the USA. Phones in the family include 1 GSM Razr V3, 2 CDMA Razr V3m, and 1 Blackberry 8700c
I wil say this about MB...to really know the electronics of these cars you end up very very knowledgeable in areas that I never intended to become aware of, let alone capable of carrying on a conversation. Geez - silly me, I thought Bluetooth was Bluetooth. How niave of me...

Thanks for the further education...
1) this European Razr cradle does not support BT at all. It should be one where you physically attach a phone on the cradle and then the phone would get charged and would use the car antenna. (Edited: a warning of incorrect info here, see later posts)
3) any HF profile BT puck would not use the car antenna in the BT operation mode. HF profile should be fairly simple and I would not expect compatibility issues for audio. Phone book download may still be an issue.
If you have a Euro UHI setup and non-SAP phones, I would assume the way forward being the Euro HF profile puck. I would expect wide support for BT telephony functions while phone book download could have the normal compatibility issues.

Are you sure re: the UHi Motorola Razr Cradle (B6 787 5868)? It has a BT botton right on the front, and the paperwork with it says it supports BlueTooth. Which takes me back to the comment about why MB would sell a Razr cradle with BT-SAP capability in Europe, when I have yet to find a BT-SAP compatible Razr phone??
After reading Skylaws excellent posts re: the Bluetooth voice quality etc. it seems I definitely would like to use the cars external antenna. It seems that the BT - SAP does this, even while in Bluetooth mode, but of course it is restricted to SAP compatible phones. That leaves me with using the phone while docked...which is ok, so long as it will work with the CDMA phones too.
I agree the BT - HFP profile seems the most universal going forward, especially now that MB has come out with a UHI HF device. I can live with the loss of charging, as long as the call quality is good. I may go that path - just not sure yet and wanted to get some opinions.

I'm not sure about the Moto cradle per the part number but I thought it was the Euro cradle and in Europe we only have (had so far) the two SAP pucks and one HF puck. Looks more like it was the US combined cradle?
It would be a strange combination to use BT SAP GSM phones and CDMA cradles, it would mean US and Euro devices used in one car. It has never been clear to me if the cradles work across regions.
More info here: Wolfgang's ML Page: Mercedes-Benz Phones
I did not find the US Moto BT capable cradle, should have looked from AWS if the part number is the same.
Another look at the issue, this page states that the part number you mentioned is for the Euro UHI too (and would obviously support BT HF). I have not seen this listed on European MB accessory listings. Interesting. Mercedes UHI and MHI Phone Cradles
Also looks like a different unit from the US version. Odd that this isn't advertised more here, RAZR isn't that uncommon even if it isn't as popular as in the US. Clearly something new to me.
My MB dealer stumbled on the UHI Razr cradle a few months ago. It came with a disclaimer regarding BT that I don't recall right now. I may need to ask him about it when I go back there in a few weeks. I'm now wondering if the disclaimer had to do with the fact that the cradle supported only BT-HF, and not the BT-SAP. Like I said, I was a bit niave about BT in general when I started this whole quest.
I guess I will end up trying all three possibile cradles/pucks and see which will work with what. Heck, I may even try the US puck and see if that works just for completeness.
I agree - the mix-match of European and NA parts is a bit of a challenge. It is something I have had to deal with since bringing the car over to the US. Trying to put the pieces together, understanding what does what, what is the same, what is different has been challenging.
Thanks for the help. I'll post with my results once I have all the pieces together.
I'm finding quite confusing info about the Euro Razr cradle. This is a copy of the W211 options price booklet, the Razr cradle cost is exactly the same as all the non-BT cradles.
Since it is supposed to be BT HF (RAZR does not support BT SAP), one should not expect the same price as for the Euro BT SAP pucks but something of the order of the Euro BT HF puck, at least. This basic Euro HF puck (part # B6 787 5877) is not on the list but would cost £250 at UK against the basic cradle price of £120.

Don't we have any owner of the Euro RAZR cradle to confirm the BT support on this device? I might try to contact the Mercupgrades.com about the info on their site too.
I just dug up the installation instruction booklet that came with the Euro cradle. It specified the cradle is for the V3 or V3i RAZR, and then goes to great lengths to tell you how to do a BT pairing.
I have also confirmed through Motorola that there is No Razr produced anywhere that supports BT-SAP. Only BT-HF. So I find myself agreeing with you - this is probably a BT-HF device, even if it isn't marketed that way in Europe.
And lingering in the background - I would love to know the difference between the US Razr Cradle and the Euro Razr cradle. It would be a hoot to find out it is only price. Once I get the car all put together, I will try them all and see what works.
Interesting price comment, although as you showed me with those CTEL Interface part numbers and prices, MB prices don't always follow logic.
I brought my parts home from Germany today, and immediately set about installing everything. I will detail this on my original "Nokia to UHI" Conversion thread tomorrow. But with respect to the Euro UHI Cradle:
1. It is unquestionably a BT - HF device, despite its billing on a number of reputable websites as BT-SAP.
2. I successfully paired a Razr V3, a Razr Vc, and a Razr Vm with it.
The last two are particularly interesting as they are CDMA (Verizon) phones. The V3 is a GSM Cingular / AT&T phone.
3. All three RAZR phones had full functionality - make/receive a call, phone book download, full BT capability, and charging and external antenna capability when docked. I was surprised by the ability to download the CDMA phonebooks but they were definitely there.
4. I was unable to pair a Blackberry 8700c (GSM). The phone found the cradle, but could not maintain a wireless connection with it. Obviously I could not dock it.
The only odd thing: None of the phones worked at first. I had to first pair the phone with Bluetooth, and then the phone would work in both the docked and undocked condition. Until I paired the phone, I received at "Please activate phone" message in the Command display.
The BT connection was functional at least 60 feet away. I was working in the driveway, and had to go into the house to power down one of the early phones I paired because it wouldn't let me pair up a new one!
expat5, my U.S. spec (MHI) RAZR cradle instructions state specifically the up to four "RAZRs" - not cell phones - can be paired with it. The instructions do not say "docked" with it, but "paired." Others have reported difficulty pairing other kinds of phones with that cradle. I have no idea why that would be the case. On the other hand, I never tried pairing my wife's LG phone - I went back to a plug-in after finding the cradle (coupled with the poor range of the RAZR when not docked, and away from the car) less than satisfactory for my needs.
I realize you have a Euro spec setup, but if it is HF vice SAP, it may have the same limitation.
That you had to first use the pairing procedure before the cradle and car would recognize a phone is normal, a security feature. That's what keeps others from just walking by and using your car's systems.
You have exceptional connectivity between your phone and your cradle when undocked. Mine was good to about 30 feet.
Thank you for sharing your experience.
