If you open the armrest to the side, it will reveal the place for the puck. The little connector will be quite obvious if it is there. There are pictures of the connector either on this forum or other SLK forums. If you search, you will probably see what it looks like. But as I said, if it is there, it will be very obvious.

:tu: In2dwww - Thanks for the info. This is a great question that needs to be answered once and for all. I think very few are aware what the requirements are for the MB Bluetooth. Anyone, any pictures available of the center console, wiring, puck, etc.? In2dwww, that's a super hot pic of a SLK 55, what color and is that what color your going with, what interior combination? Where in North Carolina are you from? Thanks!

This must be a US thing if the info they have given you is correct.

I work for these guys and i have the documents in front of me that state what parts are required for any phone functionality at all.

If you do get all the control modules included with the pre-wire then you guys are very lucky.

in2dwww, maybe somebody will chime in before but if not let me know what you find when you install the puck would you please mate thats one thing about the US models they do tend to get better equipment packs the EU ones are stupid

Do you think I have phone pre-wiring?



I found this out by accident when the upper chamber of the central console was loose one day and I was trying to fix it.

Below is a photo of the central console cover lifted up and showing the larger lower compartment. Notice the lower 1/5 is actually a cover for something with a small notch.

Pull out the rectangular cover and this is what I see:

Close up of the wiring (is this for the bluetooth? If so, what additional kit need to be purchased and installed before the puck? Does one remove the 4 small screws and just thread the wires to the upper chamber?)

you must install the phone cradle and connect to that cable there, and possibly need to connect the mic in the trunk, and then the puck installs into the cradle.

Here is what my E350 has....


First you will see an empty cradle, where the phone gets charges and connects to the car.

The second photo shows the phone in the cradle.

The third photo shows the back of the bluetooth puck.

The fourth photo shows the cradle removed, and the puck in place.

The fifth photo shows the "clip" that the phone cradle or the BT puck can pulg into. This is the clip that I am looking for on the SLK. Is this attached to any of the wiring, or somehow under the "dust cover" in the small portion of the center armrest?

From the photos, it looks like one has to buy the cradle/clip and thread/attach this to the wire located in the bowels of the upper chamber.

I do not about the mic thing -- US models have Teleaid and one can talk to them via the mic installed in the base of the rear view mirror (located in the cockpit). I do not know if bluetooth set up uses the same mic.

We need help from more knowledgeable individuals.

The Bluetooth phone will work with the TeleAid mics. The wiring harness in the trunk is connected to those by default. When you connect up the Bluetooth phone, you have to unplug a connection in the trunk and connect it to the noise cancelling mics that are also in the overhead console. (or at least they are supposed to be there, but several of us with phone pre-wiring had no extra mics in there and the dealer had to add them in. Just a matter of opening the console up and plugging in the mics.)

But the phone will work with just the TeleAid mics.

OK here is the info i have accurate as of today.

Eddy, Thats the pre-wiring for the phone you can see the FAKRA antenna connection behind the data and power feed lines in the pics you posted.

Don, Thats the OEM pre-wire to complete the kit you need the cradle for the console, hardware in the trunk both the "core" and "completer" kits are required to enable the phone and a mic array once they are installed and coded the system will fully integrate with COMAND and the IC.

in2dwww, For your model year there is a certain amount of guess work involved because the tech docs are not all finalized but if its the same as the 05,06 and 07 MY's then you will not be able to use the phone right from the get go you will have the same as Eddy's car and will need hardware to enable it.

The plastic cover snaps out so don't try it on cars on the lot it will be very messy indeed, as you can see from Eddy's pics and as you correctly point out the cradle connects to those sockets that harness then leads into the trunk where the control units are required for all the model years up to 08 and possibly for 08 also.

Do you have a VIN for your car yet so i can run it for you?

Eddy and Don, you will need the core kit that consists of the control modules and the linear compensator.

Part number - BQ6820955

And the completer kit that has bracket and adapters for the SLK.

Part number - BQ6820915

You might also need the Mic Array PN - BQ4820122

Its interesting that the latest TSB for this now says to add the Mic Array so it would appear that the latest models are coming off of the line without them installed and this is what is wanted by the factory.

It never used to be like that they where in automatically however it looks like just the TeleAid mics are now fitted

phone pre wire ?

I have been following this and many other posts concerning if the SLK is pre wired for a phone (bluetooth), I also have the wires visible in the console and wondering if any of you followed up with a installation. I have gotten so many conflicting views and prices for a install, Im hoping someone has a difinitive answer. Thanks guys, great posts
 
#17 ·
From MBUSA: if you order the car with the Hands-Free Communication System installed at the factory, it is a $925 option, i.e., the core kit, completer kit and mic array are installed at the factory.

If you install the components later after delivery, the dealer will charge more than $1,000 (close to $2000 according to one salesman).

:tu: Can you hear me now? Bluetooth, it's big and getting bigger. I'd say that factory Bluetooth is going to be virtually standard in the next few years or one of the most popular options purchased. I recently installed the Parrot Bluetooth kit in my wife's SLK 350. I tried the optional steering wheel kit for the MB, but couldn't get all the functions to work. Finally, I removed the steering wheel controller and used the hand controller supplied with the kit. It works fine and my wife loves it. You can find the Parrot Bluetooth kit at ParrotKits.com. Here's a link to a "how to" on the Parrot system I did back in January with some updated information: http://dz1.homestead.com/ParrotBluetooth.html. My newly acquired 2005 SLK 55 came with the factory/dealer installed MB Bluetooth kit. It has the "puck" in the center console and you can use ANY Bluetooth enabled phone with the system. The only function I can't utilize is the downloading of the phone book from my phone. To get that, I'd have to buy a Motorola Razor phone and the docking cradle for that phone and remove the "puck". Probably, $400-$500 minimum. It does everything else. Hand free, steering wheel control, dialing from the Command, number display in speedometer menu as well as the Command screen or Audio 20 radio. It works well, I'm happy with it. Glad it's there and a fun feature. Yea, I'd spend a $1000 to retrofit a car without it. I considered removing the Bluetooth system from my car to my wife's but she's happy with her Parrot kit. She would use it more than I, but I'm glad I get to keep it. I like neat electonic stuff and this is one of them! I'd suggest the factory/dealer installed Bluetooth system if possible, but the Parrot kit for the MB SLK is a inexpensive fully functioning alternative (minus the steering wheel controls).

Update on Hands Free Communication System

:tu: Can you hear me now? Bluetooth, it's big and getting bigger. I'd say that factory Bluetooth is going to be virtually standard in the next few years or one of the most popular options purchased...
I just learned from the parts people at MB that the Hands Free Communication System is standard on the 2008 C class (at least for US models). Don is spot on in his prediction that this will become standard. :tu: Moreover, this Hands-Free system can pair up to 10 phones instead of 4.

I had the Hands Free Communication installed today. Please remember that pre-wire means you need to have the core kit, completer kit, the MHI Bluetooth module installed (it's still a dealer-installed option for the 2008 SLK).

Here's a list from the work order:
1. Supporting P (don't know what this means or what this part does), part no. 203-820-14-11, retail price $104, trade price $88.

2. Vehicle core kit, part no. Q-6-82-0965, retail price $965, trade price $791 from oempartsdirect.com.

3. SLK completer kit, part no. Q-6-82-0915, retail price $640, trade price $524 from oempartsdiect.com.

4. MHI Bluetooth module, part no. 6-7-87-5878, retail $420, trade price $357.

5. Labor 3.00 units, $375.

Total retail price for parts and labor: $2504, sales tax is extra.

Total trade price for parts and labor: $2135, sales tax is extra.

I hope the above clarifies what is involved in getting a Hands Free Communication System installed in a pre-wired vehicle.

Ive got the Mercedes Benz Bluetooth UHI and its works fine and the sound is very clear no problems so far.
FABULOUS!!!! GREAT TO HEAR!!!!

"UHI" Can you explain the acronym please?

ahh..
Universal Hooker Interface?
Unusual Human Interaction?
Unbelievable Hottie Inside?

Annnnyyyyway... I have my Mercedes Benz dealer installing BT (BlueTooth) and I blew my top when he tried to charge me $2000. I walked toward the door and started to make a scene Frikin Fracka @$*%$ Mercedes can KISS MY Frickin Fracka!

Eventually, we settled on $900 for the Entire Thing - Out-the-door, installed tested and working!

Just, how do you justify this **** when a $20K Nissan has BT in it? HUH?? can anyone tell me that?? Greedy Bastards... and it's not that the dollar is weak and the Euro is strong. I'm not buying it! The Japanese give us way more toys for way less money, and you don't hear them crying about profits... Yep, we delivered the Bomb and THEY won the War.

Holy **** that's expensive for a feature that should come standard with the car. My G35x, which costs half as much as the SLK55, has bluetooth standard with the Premium Package and allows me to control everything from the wheel and voice commands. I simply push the phone button on the wheel and say "call", then either a number or a stored tag, and it calls...

Just for reference the BMW system that has been using Bluetooth for a good few years now costs approximately half as much when dealer installed and less when done at the factory.

:)As a minimum, MB needs to clarify the Bluetooth option and pricing for the SLK for consumers to understand. If it wasn't for these forums, we wouldn't know. Dealer installed is just a tactic to increase profits. With the popularity of Bluetooth, it should be available as a "true" factory option and pricing should be more in line with what's charged by other car manufacturers.

MB Bluetooth Revolt!!

:)As a minimum, Mercedes Benz needs to clarify the Bluetooth option and pricing for the SLK for consumers to understand. If it wasn't for these forums, we wouldn't know. Dealer installed is just a tactic to increase profits. With the popularity of Bluetooth, it should be available as a "true" factory option and pricing should be more in line with what's charged by other car manufacturers.
I am brand new to the forum and this is my first post. I ordered the SLK55 yesterday and after the deal was struck, the business manager told me when I inquired re: bluetooth, "you're not going to like this... $2700 for the OPTION???" WTF I said!
After $71K, Mercedes Benz is gonna bang me for another $2700 when my Camry Hybrid has an entire system installed in it for $30K? (Comes with the Nav Pkg) SO it's complete BS that MB cares about your safety and comfort. BT is a nescessity NOT an option. You'd hit a tree digging out a phone from your bag at 75MPH... maybe. In my Toyota I have the entire system with 1 button press.
As I thought about it, I started to FUME!!! I got up, and began to walk out of MB of White Plains. You can keep your car I told them. The Sales Mang came out to calm me down. 1 day later I have an SLK55 with the entire BT installed for $1000. I'm still PO'd! But it's better. BTW my Acura RL has BT in it too. NO OPTION! MB is a money grubbing company who tries to take your last nickel. They need to come back to Earth and get with the program. They are idiots... hide the Option in the price of the vehicle and give BT away. This way we never know we're being screwed with a smile.

Eddy mate,

Since i don't keep VIN's would it be OK for you to PM it to me again and i will see what options actually came with the car.

I don't know what the "Hands-Free Communication System" actually relates to is it wiring or are there control units fitted
 
#30 ·
PM sent with VIN.

Eddy mate,

Thanks for the VIN i ran it past the computer and it looks like what MBUSA are calling the "Hands-Free Communication System" is the MTUS Pre-Install.

So that includes all the wiring and the parts inside the center console to accept the cradle it also has a few control units that are different from a car without the phone like the antenna splitter ready installed.
 
#32 ·
Thanks Dan. What does MTUS stand for? -- must be something for the US only.

Mobile Telephone United States

US and Canada thing but it works in any country with the right antenna booster fitted.

I need to find the right code but Merc do offer a kit with a bluetooth module already fitted behind the upright storage bin.
 
#35 ·
So, unless it is expressly written "phone pre-wiring" on the vehicle description, the car doesn't have it? My car is an '06 with Lighting, Entertainment w/ NAV, & Premium Packages. I am also interested in adding bluetooth. If it matters, when I looked closely at the lower compartment, it had a small oval-shaped cover with a notch in it.
