I also noticed this while I was reading the manual for my '05... That Mercedes may offer an AUX input for the '05 radios sometime soon. That all you need to do is press and hold the Changer button and it will say aux, and that it will be a dealer accessory "that may be available". Anyone have any news? Will this be another b/s $300 audio cable? Thanks.

i'm interested about this as well :-)

Ask your dealer for the wiring harness A 203 540 61 07 (should be about 30$).
There is a connector (male, 4 pins) located inside the right door sill near the A-pillar. When you install the A 203 540 61 07 into the glove box on one hand side and connect it to the vehicle headunit harness, you will have your Aux-In option.
This only works with MY05 and later vehicles. Be sure your headunit supports Aux-In (press CDC-button for more than 2 seconds).

hmm... very interesting. thanks so much for the info! anyone want to try this? I really suck at mods, so I don't want to be the first one (I need pictures to guide me).

please do post pics!

i wonder if the removal would be similar to the removal of the 01-04's i would suspect it wouldnt be much different. the radio removal im sure is different. check out the audio10 install thread for the removal of an 01-04 console and see if its similar to yours.

@jucarbon
Where do you buy original MB spare parts? Try your local MB dealer!
You needn`t remove the headunit, as the plug for your Aux In harness is located in the sillar!
Sorry I can't post any pictures, as I haven't done any mods like this. I'm just a designer for wiring harnesses.

Thanks cc4469, I was wondering if you could please clarify "sillar," I'm not that well versed in these terms, and I was wondering how much of the paneling I would have to take apart. Thanks!

I'm not sure if the 05's have the same set up...maybe Steve or Sunman can confirm...but there are 2 ways that an aux input can be hooked up on the pre-05's. The first is hardwire it straight into the command unit. In which case you have to remove the connector on the end of the aux cable and crimp the wires (pic 1) then wire it into the C2 connector in the back of the command. Or if the car is pre-wired with the aux-input then the cable is already wired into the headunit and from there the cable is threaded down the side of your car under the door sill with a plug on the end similar to pic 2. All you need then is the aux-cable containing the input plug on one end and the female connector on the other (which you plug into the white connector in the door sill). This is what cc4469 is referring to.

Again, I'm really not sure if the 05's are the same.

cc4469

@ nlpamg: Sorry, of course not "sillar" but "door sill" (I'm not a native speaker of the English language).

@JeT: yes, the connector is the same with Comand before '05 and with ANY headunit from '05 on in the C-class.
JeT's right picture shows the connector to which the Aux In harness must be connected - that's it!

I've got an AUX input hardwired into my OEM head unit, so I know it can be achived for pre 2005 cars. The 1/8 inch jack is in the storage tray underneath the HU. I didn't do the technical work though, so I'm not sure about any of the specifics.

nlpamg

cc4469, don't worry about it, I really appreciate your help, I just don't know what's what so I'm pretty ignorant on a lot of terms.
Thanks for the pics and info Jet.
If it's under the door sill, then I'll probably just have the dealership do it, I don't want to mess anything up.

Conundrum

So we only need to buy the connector as pictured and install it to another connector location in the door sill.... is that it?

Any one have picture of the whole installation?

thanks

jmartinacevedo

If this is in fact true, I think it's a great option to have for those of us who want to direct-connect XM or an Ipod into a MY05 Head Unit!! Yeah!
Someone please post pics of the location of this AUX IN jack and the cable/wiring harness that's needed!

THanks!

Are u saying that an AUX IN connector is available on pre-2005 C-classes WITHOUT Comand? (I thought only cars WITH Command had the AUX IN option)?!!!

Thanks.

I think what JeT was saying was that Command comes with everything wired and installed. But you can still "cheat" by making your own AUX connector equivalent to the Command one.

Blake P

Are you sure?! :p

20FHK02

Hey at least you've got an AXU in!

A test: try to hold the CD key for 2 sec and see if you see anything interesting.

JeT

Sorry 20FHK02, that's not what I was saying...As far as I know, this is only for the command...not for the Audio 10 or Audio 30 etc.. But just because you have the command does not mean you have the aux cable already wired into it. Althoough the US cars appear to be pre-wired for everything else I don't think they are prewired with the aux input...so you will need to buy the aux-input cable with the input jack on it (I think the part number is A210-440-50-05), strip off the connector on the other end, crimp the wires (as shown in the pic above) and then wire it directly into the C2 connector in the back of the command...this is what Steve does in all his installations I think.

My command wire harness (which miroj kindly tracked down for me) happens to have the aux input already incorporated into it which resides down under the door sill with the white connector (pictured above) just sitting there. So all I needed to do was buy the aux cable and plug it directly into this connector in the door sill.

jmartinacevedo

Here's what I believe we've learned so far:

1-There is no AUX-IN factory option on pre-MY'05 cars without the Command. In other words, there is no AUX IN factory option for pre-MY05 cars with the stock headunit (i.e., Audio 10 or Audio 30).

2-According to the poster from Germany (cc4469), for MY'05 cars (with the basic cd headunit - no Comand) there is an AUX IN factory option which can be implemented with a certain cable/harness (Part Number A 203 540 61 07) and which can be accessed by pressing the CD button for 2 seconds.

Can someone with a MY'05 car press the CD button for more than 2 seconds to see what happens?

Thanks.

jmartinacevedo-

I held the CDC button on my '05 with the stock stereo system and it does indeed bring up an AUX Input setting. So all '05 cars should have this.

Hope this helps.

tyro

So what are you guys hooking up to your Aux input?

jmartinacevedo

Thanks for doing that. It's great news. Can't wait to get my MY'05!
