I am in the process of installing the bluetooth kit to my 2008 CLK350 (with prewiring).

I have done lot's of recon work and the only thing I haven't been able to access is the MOST coupling on the passenger side transmission tunnel. The diagrams I have do not show how to remove the plastic cover that is behind the carpet. I can get to that part fairly easily but need help from there.

Also if anyone else has installed this kit and has any advice that would be great.

Thanks.

Hey MBA, I am in the process of the same, with an OEM Bluetooth install, but several months behind you. Were you ever able to get access to the MOST cables? I got the 2005 CLK Star Bulletin, (off the Cartronics site). It shows pics of an "exposed" trans-tunnel, but I think from 2006 up this completely covered with carpet. Where approximately is the plastic cover you accessed? From the *Bull pictures it seems to be just behind the front seat driver side 'cause I can see what appears to be the flexible seatbelt post. Did you have to remove the seat in order to peel back the carpet? Thanks for blazing the trail.

MBAgain

It turned out that I didn't need to make any changes at this location. The carpet will come loose without removing the seat but I could not see the cables. There was a plastic piece under the carpet that blocked the access to the cables. Sorry. Someone else on here will probably jump in to help.

Thanks! My guess is your ride was preconfigured with or without satellite radio and you kept it the same. unfortunately I'm adding Sirius as well and i may need to change the configuration to insert both BT and SAT into the MOST LOOP. I will try to do the install with reconfiguring if that works great if not, i'll need to dig deeper. "Preciate the help!

MBA, how did you not need to make changes there? I'm in the process of doing mine, and my notes say that I have to change the coupling there to "tel out>cdc in" and cellguy85 said it likely now is "sound out>cdc in"

I already had Sat radio and cd changer in the loop. I also had the pre wire for phone. It look like that everything in the tunnel was already configured. I did have to rewire all the trunk fiber links as per the instructions from cellguy.

I got real lucky as I never did figure out how to get to the fiber optics in the tunnel.

well, I installed the puck bracket first and I'll tackle the trunk next. That interior carpet scares me most. I want to get the aux input cable for the glovebox next.

Sirius up and running!! Looks like in the manufacture, some of the fiber optic cables got stuck up higher in the center stack almost behind the nav/HU. I'm glad I didn't just yank hard! Had to remove the shifter surround, then ashtray, and climate controls, and the orange fibers were visible. Everything was actually extremely easy to remove, just the pucker factor. Everything is very clearly labeled with paper tags and if you follow the Star Bulletin instructions, it is a piece of cake. Also I did the hidden antenna installation by sticking a tiny magnetic aftermarket Sirius antenna on the sheet metal under the rear hat shelf ("rear dash") and routing the (extra long) single lead behind the trunk liner. I Highly recommend ordering the splitter from mercedes as opposed to getting the audiovox adapter because the FAKRA connectors are not going to fit and you will have to remove them. The mercedes part number for the splitter is B6 783 0058. It will allow you to connect any new single lead antenna, OEM or aftermarket to the 1st generation sirius modules with 2 antenna inputs. (you may have to remove only the plastic FAKRA connector for "ANTENNA IN" if it doesn't fit, THE ACTUAL MINI-COAX CABLES UNIVERSALLY JOIN) Anyway thanks for all the help!!!! NEXT PROJECT>>>>BLUETOOTH!!!

Oh yeah, The MOST loop did have to be reconfigured after adding the new components. That is what the orange fibers in the transmission tunnel do. They apparently send the light signal through each component in the fiber optic network sequentially and allow each piece to function. For example without configuring at the tunnel and in the trunk, I could turn on everything and it recognized it, but no sound at all. Nav still worked, but all you have is visual display, but no verbal directions. What apparently did NOT have to be done in my car was to take it to the dealer to hook it up to the computer to program the loop. It just worked. The M-B mechanic seemed very surprised everything worked without the "programming" Maybe M-B urban legend to discourage DIYers from working on our cars?

I know this is an old thread but, I have searched around and still can't find the location of the "transmission tunnel" in my 08 clk. I am in the middle of a BT install and believe this is the last step (for me).

Can someone point me to the location?

(a picture would REALLY help ... and not the one in the manual LuLz)

eddieo45

assuming you're in the US, right side (passenger side) of the console is what I think you're looking for....

temper

Thanks................
I'm looking , found wire no optic cable............

temper

Could it be under the shifter ?

eddieo45

you've got to "tease it out." How much of the carpet do you have removed? I tried to remove as little as possible and was driving myself crazy. Eventually I dug around into the console sides shown in Figure 13 HERE and pulled them out (with well-scraped knuckles.)

temper

THANK GOD and eddieo45....................GEEEZ..........you were right !
I found it..............
Thanks so much!

Hello,

Apologies in reviving an old thread, but would temper or eddieo45 happen to have pictures of where the MOST wires were pulled from the transmission tunnel?

Thank you very much!
