Bluetooth Hands Free - Some Answers

Okay. Thanks to everyone that replied, it helped make this information quest a little easier. After numerous enquiries around the Internet, I think I have all the answers I need. If I've made any mistakes, please feel free to chip in. Mods, I'm not sure if this is worth a sticky, but it might help clear up some of the questions on here! Here goes.....

New 2008/2009 Models

1. These cars come with Bluetooth as standard. This means you can, without ordering any special extras, take any Bluetooth compatible phone and enjoy some level of functionality, be it simple hands free or extensive use of the cars controls and COMAND interface.

2. The level of functionality available for some phones and the standard Bluetooth fit is listed at this website:

Select your country, then car class, then "Bluetooth Connectivity", then "Compare All" to see a list of features

3. The Bluetooth protocol used for this standard Bluetooth fit is HFP. This simply means that your car will talk to your phone and share some of its features. Using this system, phone calls are made through the phones antenna, not the cars. The phone is effectively 'live'. This integrated system replaces the functionality of the Bluetooth HFP cradle:

4. If you wish to use the cars antenna to make calls (this way the signal is boosted) you can do one of two things. Either a) Buy the correct cradle for your phone (if it exists) - a decent list of available cradles can be found here:

http://shop.mercedes-benzofmiltonkeynes.co.uk/catalog/index.php?cPath=141

or B) use a different sort of Bluetooth. By purchasing one of these:

your car will use the SAP Bluetooth protocol (be aware that there are two generations of this product. You want Version 2). The difference being that the car will take ownership of your phone, and place it into a hibernation state. The car effectively downloads all the information from the SIM card in the phone and uses it to conduct telephony. Again, be aware that not all phones support the SAP protocol. It is part of the Bluetooth Version 2 specification which is becoming standard amongst newer phones. Nokias seem to be the best supported. To the best of my knowledge, Apple hasn't adopted it yet. Another point to note is that irrespective of who makes your phone, 3G models will not work with the SAP protocol. They can still be used with the HFP protocol however - that is to say, the standard Bluetooth fit.

Both methods will allow the use of the cars antenna and maximise the feature set available to you in the car. This should include, amongst others, reading and replying to text messages on the COMAND interface should you have it. To view a list of features available when using a phone specific cradle, visit:

http://www.mercedes-benz-mobile.com/service

Select your country, then car class, then "Comfort Phone System", then "Compare All" to see a list of features.

5. To use either of the cradle types, you must have Optional Extra 386 - Telephone Pre-Wiring installed. Mercedes assures me you do not need any of the other options (388 - Universal Interface, for example) installed.

Thanks for the very thorough listings. Having this info all in one place is really helpful.
Hi guys,

OK, I am going to throw a curve ball now. Here is my question...

I have a MY2005 (Built Dec 04) 350 which came with the crappy Audio 20 of the time. The car also has phone prewire with the cradle in the armrest. I used it fine with a Nokia 6310i and the MB cradle.

Today I replaced the NTG1 Audio 20 with a new NTG 2.5 Audio 20, so get Bluetooth, CD changer etc etc. All lovely and an adventure to get all the stuff fitted with adaptor cables. The bluetooth works fine with a couple of phones I tried.

So, I would like to use the built in cradle to charge the phone and take advantage of the booster for the antenna. On my other MB (MY 2009 E220 with NTG2.5 Audio 20 and phone prewire) the cradle works fine and when I choose Bluetooth telephones in the menu on the radio, I also have an entry for Convenience Tel, which then works like the old prewired SLK radio (no bluetooth required). On the new SLK Audio 20, this option for Convenience telephone is missing, and I can only choose Bluetooth phones.

I plugged the MOST cables into the quadlock connector so it should see the phone kit, but nothing happens. When I put my old Nokia in the cradle between the seats it tells me to disconnect Wired Accessory and then goes to sleep, so I guess it cannot use Bluetooth and the phone prewire at the same time (this may be due to the phone being ancient to be fair).

What I need to know is, should the menu items for a convenience telephone be available on the new SLK Audio 20 (maybe not as I think that Bluetooth is the new method of getting a phone in the car), and if I use the cradle with a new phone (iPhone etc) will it still use the external antenna and work over Bluetooth?

Thanks

Downloading Contacts in Comand 2.5

Hi,

Guess that I'm not the only one to end up with this problem, so there might be some one that has a solution for this.

In my BMW (sorry, have that as well) I can import all the contacts to the car and then navigate directly from the phone book (in car), or use the phonebook via Bluetooth.

For my SLK 350 (MY-09) I can download the phone book via Bluetooth, make calls from the car, but I can’t navigate! I can see phone numbers, addresses, both work and home but the small compass (symbol for complete address data from the navigation) will not show up. So, I thought that there was something wrong with the phone (SonyEricsson G900) and tested with my old phone (SonyEricsson W800i) with same result. Tried with my wife’s phone (Nokia something) and had the same result here. Contacts are imported (via Bluetooth) and I can see them and call, but not navigate.

Cleared the entire address book and started again with importing from an SD card. Now I had all contacts as said from MB, vCard format. No problem to import and everything is seen in the address book but still not possible to navigate!

Grateful for all kind of suggestions here.

Hi Guys, I suppose I am correctly entering here rather than commencing a new thread, let me know if not....

Car is 2006 SLK AMG with 386 UHI and Comand when I bought it I had a Nokia 6230i and bought the cradle for it which worked fine. Upgraded to iphone 4s and didn't bother with the new cradle at the time. Then due to change in circumstances and likely to use the SLK more decided to sort out the 'phone. I just purchased from Ebay a cradle for the iphone 4 (part number A 212 820 11 51 with the media cable) and today I have been trying to install. The instructions are not exactly 100% !! After you have slid the cradle onto the connection under the arm-rest you are told to put the phone in .... then it says that to pair the bluetooth the phone must be in the car but NOT in the cradle, so I took it out again..... follow instructions for bluetooth pairing:
turn on ignition
press button cradle so light flashes quickly
switch on phone and bluetooth on phone...seconds pass and the cradle is detected
select cradle on phone and tap in pass-code
whirly wheel and "Connected" comes up - GREAT you think (there should be a constant light on the cradle now but there isn't)
after about 5 seconds "Connected" changes to "Not Connected" and the whirly starts up again.

I should mention that in my '57 Honda the phone connects everytime I get in the car without a problem.

I did try to connect it via the Comand system as well and it went through all the motions right through to entering the code and then it decided it wasn't having any and that was whether the phone was in the cradle or not - (I was not expecting this to work so I was not disappointed)

I've really been on this for hours and hours and thought I had tried every permutation of phone in or out of cradle and system and (what I consider to be) the correct method many many times, so now I'm getting a little frustrated

So ..... anyone any ideas ..... Got to pop out right now but will be back later and can always spend tomorrow trying to get it going again - be extremely grateful for any suggestions.

I do concede that the part-code number is slightly different to the Mercedes one listed for the car but the item looks identical - I'm assuming that the code difference is because I have the one with the audio cable whereas the one shown in the Mercedes documentation doesn't.

Thank you in advance for any input

Bob

Finally Bluetooth (Spotify) Streaming to my SLK R171 with Comand APS NTG2.5

This is the key "Automatic reconnection every time you enter the vehicle. Simultaneously use the original or after market Bluetooth handsfree phone and automatically switch between music playback".

Some require a reconnection/repairing every time you turn the power on. Automagic is good.

If you have an aux input jack (3.5 mm) then this should be all you need.
Our car was first registered 21st May 2008 so smack on the changeover between having Bluetooth & not having it, any sure way of checking, I didn't see it in the menu from the steering wheel controls.

Thank you very much for that, I hadn't seen that, I'll have to wait until it's light, or maybe it'll be on the V5C/2

In usa, the vin is on car in 5 places at least
on your insurance paperwork and on your registration paperwork
We have it under the windscreen on the front panel, it's also on the Reg docs, but they have to go straight to the authorities on purchase responsibility of the seller, we then have to wait for the DVLA to send them back to us.

R171 facelift (2008)

In January 2008 at the Detroit Motor Show, the SLK-Class facelift was launched, following pre-show announcements in December 2007 with the first American owner being James Glass of Johnson City TN.[9] The R171 facelift included new engines, with a particular improvement to the SLK 200 and 350 with more power and better fuel efficiency. The exterior changes were subtle, with alterations limited to the front bumper design and new wing mirrors.[10]

SLK 200 Kompressor – 1.8 L 135 kW (184 PS; 181 hp) I4 supercharged engine
SLK 350 – 3.5 L (3498 cc) 224 kW (305 PS; 300 hp) DOHC V6 engine
SLK 300 and 55 AMG retained their existing engines

Looking at the pic, it's almost certainly a pre-facelift (different indicators in the wing mirrors to a post-facelift)... but don't compare them to mine, as I've changed them to pry of the post-facelift mirror covers. :D

That's what i'm expecting didn't even realise there was a facelift version, it was too dark this morning when I left for work, I should be home in time to get the vin off the scuttle tonight.
