Found a good Bluetooth phone interface option
http://www.ebay.com/itm/271359691022
The seller accepts "make an offer" so I did and save almost $15. This should work on all CLK's (or C-class) cars from MY2005 and later that use the MOST fiber network.
I installed in the CLK and it was an easy job. I just tied into the connections for the CDC. I had one problem with the COMAND lockign up after a few minutes, but that ended up being an incompatibility with loading the phonebook from my Samsung Galaxy SIII. Once I disabled phonebook upload, all was well. Phone control uses the standard buttons on the factory radio and steering. The CDC "discs" select various menu options like playlist or artist on the iPod. It uses text display on the COMAND so it is very easy to use. I don't believe the standard head unit supports CD text, but it would still work, you'd just need to memorize the disc button functions. It's fairly intuitive, but I think COMAND users will be happier. If you con't have COMAND, the OEM iPod kit might be a better choice as it uses the instrument cluster MFD for text display. Oh, and the two can coexist with no problems.
Overall, I am very happy with it and the cell phone sound quality is very good. Let me know if you have nay questions.
My crapol-a Visseo MB-2 puck does not do siri and only works abut 75% of the time. I was going to change it out for an MB-4, but this is not much more....AND i'd get the iPod info on the main screen instead of the MFD that only displays 7 letters....
interesting. Can you keep us updated on your feelings?

@Klonsbury: The beauty of this device is that it does not need pre-wiring or anything - it just goes in place of the CD changer and emulates all of the MBZ OEM phone interface "parts".

I connected mine and left it in the glove compartment, connected to the CDC wiring for testing. Now that I have everything working, I'm going to put it in the dash. I may try to put it next to the TCU under the passenger floorboard if the wiring will reach. If not, I'll put it in the dash - there's room below the COMAND unit, behind the ACC panel.
Oh, and on the lock-up problem I had due to the phoen book download, I have been in touch with mCAR support and they noted that the COMAND can only handle a maximum entry name of 30 characters, and some "special" symbols may be problematic. So, I cleansed by phone's contact list today and I'm going to try the phoenbook download again this weekend.

I just used "vampire taps" to connect to the CDC's power leads. The mCAR's black ground wire goes to the CDC's brown wire (remember brown = ground on MBZ wiring) and the mCAR's red +12v input goes to the red+blue lead on the CDC connector. Route the microphone to the sunvisor or overhead control panel and that's it - no need to break into the dash.

Seriously, I just don't like clutter and I am slightly OCD - electronic components and wiring have a place and it's not just sitting around in the glove box. Besides, I am going to remove my OEM iPod interface (look for it for sale here soon!) and I have to pull the radio and the passenger floor panel for that, so I might as well install this right while I'm doing it.
It's a nice clean install. Oh, and I removed my OEM iPod interface and will be selling it. I'll post it on the forum in case anyone wants it.

As for the floorboard access, it's easy - just pull the carpet down from its top edge under the dash on the passenger side. Only the sloped part comes down. You then remove a foam insulation panel behind that. Now there is a metal panel that has three plastic nuts holding it in place - two on the bottom (you have to feel them, you won't be able to see them without a mirror) then one on the top right corner.
as for the mic, I loosened the OCP and "wedged" the mic between it the small strip of headliner. I then ran the wire down the A pillar on the passenger side and down into the footwell.
Any updates now that you have had it for a while?
My POS MB-2 dropped another call today and then refused to sync or release the phone so I could hold it to my ear. I had to pull over and physically remove the puck from the UHI and sit there by the side of the road and hold the phone to my ear. Ive had enough.
Im hoping it streams via bluetooth as well...
thanks in advance.
I really don't use BT audio streaming, but I did try it and it worked fine. My hearing is not good enough for me to give you any "quality" opinions on it. Also, the iPod integration is great - IMHO, much better than the OEM cluster-only display. Liek I sadi, for the price and the features, it's great.
In your case, I think you'd have to remove the factory phone interface to make this work.

as all have commented the interface is goofy but given the device works by emulating the factory cd changer i think it does a remarkable job on bt streaming and the phone works.
a better answer is likely one of the latest generation touch models out of china but that "roll" would be about double the price of one of these.
i suspect the microphone included in the kit probably costs less than $5 and maybe an upgrade will help. looks like a generic 2.5 mm
Does your phone auto-pair when starting the car? (Can anyone vouch for an iPhone?)
Do all the features work the same when connecting via Bluetooth as it does USB?
For example, when connected via Bluetooth, do song tracks display on screen?
And can you change tracks with the steering wheel and Command seek+/- buttons?
Just want to double check that you don't need to take out the Command head unit to install this and that you only need to work inside the glovebox.

My android phone autopairs but no i-experience.
Track selection and volume buttons on wheel work.
I tossed a bunch of mp3's on a usb stick but the device always starts with track 1 and moves sequentially.
I think the bluetooth streaming is probably the coolest feature and I am pretty sure the playlist gets scanned like any other media.
For the $ I don't see how you can do better-but this is not how Fritz would have done it, and it shows...
@Pilk: No, this is for MOST systems only, introduced with th My2005 "facelift". Your MY2003 has D2B. There are some options for it, but they are becoming harder (and more expensive) to find. Your best option may be a head unit swap. In fact, aftermarket head units look better int he pre-facelift cars than in the post-facelift setup.
