Hi folks,

Got hold of the M2 pro from mObridge. But now I don't have any idea how to go about installing it. There are no videos on YouTube showing how to install it. If anyone here has any experience I seek your help. Thank you.

Hi....is anyone out there...who could help me get this installed???

Could you post some pictures of the device? Especially the connectors. This might get you more replies.

Yeah, I've installed two in my previous 220's. Great unit BTW. It's not a horribly technical install but if you're not familiar with removing the trunk liner, bypassing the CD changer's optical connections, removing COMAND, splicing into power and ground, and changing the routing of the fiber optic cables you may want to have it professionally installed.

Just remember this: The fiber optic signals travel around a loop containing the various components...CD changer, XM radio, navi, phone etc. Each component has an optical in and optical out. Each component must pass the light along to the next component. If not, nothing on the loop functions. If a component is removed from the loop and the connection isn't closed off with a bypass, nothing works. If any component has no power, nothing works.

You'll be bypassing the CD changer in the trunk, "tricking" COMAND into thinking the Mobridge is the CD Changer. You have a little bypass adapter in your install kit. It just snaps on to the factory CD changer connector and closes the loop.

COMAND needs to come out. There are tutorials for that somewhere. Very easy...one #20 Tork bit does everything. You need to tap power and ground for the Mobridge from the existing COMAND wiring harness (thick brown wire is power), and then install the Mobridge into the optical loop. That involves disconnecting the optical connector from COMAND, removing the orange optical cables from the connector, and re-orienting the cables so that the MoBridge is now part of the loop. The MObridge can be laid flat and pushed to the very rear of the dash cavity. Then button it back up and you're good to go.

It takes me around 4 hours to do one. Just go slow, and follow instructions (which suck BTW) It's a little unnerving having your COMAND out but there's not much you could do to damage it. Just make sure the power and ground connections are secure and taped off. It may take some trial and error as far as the optical cable orientation so just keep playing around until everything lights up and the car is happy.

...when you disconnect the fiber optic plug from the back of the radio and look closely you'll see two orange cables into a black clip. There are two directional arrows on the connector clip showing In and Out. In the middle of the connector is a tiny square of either blue or grey plastic. Push that piece out with a small screwdriver and the connector will open up. Then you swap the Out cable of Comand with the In cable of the Mobridge and vice versa, reassemble the connector, put the little locking tab back in and you're done. If you don't get audio swap the positions in the connector. While Comand is out, route the aux in and iPod cables and bypass switch into the glovebox . There will already be a hole for that purpose.

"...(thick brown wire is power), ..."


Mike,


I haven't done this, and you may be correct - but the DIN Standard for electrical wiring color (which Mercedes follows) says that brown is always ground (earth).

Mike5215

It's possible. It's been a few years since I was into the dash on a 220. Power will be the heaviest gauge wire going into COMAND. You won't miss it. Where's the OP? I hope I didn't scare him off with all that fiber optic stuff. It just helps to know the concept of a fiber optic ring if you've never dealt with one. The install itself is pretty painless.

Ok...thanks for this input. I too remember that brown was ground. Will check anyways. Yes Mike, I'm a bit confused only with the fiber optics... The install guide that came with the box is very confusing. You've given me a fair idea of the whole thing... I'll try and follow your steps. Hope it works out. Would appreciate it if you could run the bypass by me once again. How do I get that done again? What about the phone?

These are the components in the kit I had received...

Mike, waiting for your reply...

I've been looking at the MoBridge products. Any updates on completing installation? If so how is it working? Do you lose CD Changer functionality? Thanks Mick

Hi guys,

I'm a new member and this is my first post.

I recently had two M2.Pro MOST units professionally installed - one on a 2004 S600 and they other in a 2006 R500.

On the S600, the phone integration works, but the data does not synchronize with the 'TEL' function on the COMAND system. I can place and recieve calls using my phone to input, but not via the COMAND interface. The COMAND system says 'Tel not inserted'.

Any ideas how I can fix this?

The unit in the R500 seems to be working with no issues.

Mobridge's site has a video of this working perfectly with a 2004 MB - I'm hoping there is something I can tweak.

Thanks in advance for any suggestions.

Scott

I have a Dension Gateway 500S BT. It also handles phone and I was getting errors also with the phone book. I turned off the phone book on my Gateway 500 system settings and it runs much smoother when it is not stuck trying to sync contacts. I am not sure of the system settings on the M2, but sometimes clearing the bluetooh pairing list and re- pair (sync) to your phone might help it lock on to your phone. If you have a rear mounted CD Changer, you will need to re order in the trunk the fiber connection order. The Install thread will cover that.

This thread helped me a lot on the install
