Ok guys Ive searched and searched. I have the nav package with the ipod and aux input jack in glovebox. I have searched every possible option and gone through every possible option and engineering menu that says aux is enabled. Aux is not a selectable option anywhere in any menu. gone through disc, changer, music register, memory card, etc etc. Even put a disc in just so i could highlight the "cd" to change input and still doesn't show up. What the hell am i missing here?? Very frustrated, i want to get the adapter to stream bluetooth, but if i cant even select aux whats the point? Only inputs listed are: disc 1-6, memory card, and music register(hdd)

What's plugged into the aux port?

cptncreme

Plugged a 3.5 mm cable into it and connected to my phone

Don't know about the W204, but in the W164 ML when you have the iPod interface installed the aux input will be disabled. Perhaps this is the case?

There's no AUX button on the head unit?

cptncreme

Nope, only radio, disc, nav

My mistake, there is no aux button. The only way I can get aux is via the COMAND onscreen options, which honestly I find annoying bc of the extra steps. That's is strange that you don't have the onscreen option. If no one here chimes in, it may be worth an ask at your dealer.

Dumb question but often dumb questions beget good answers.
Have you searched the manuals for an answer? I have always in all my cars since 2003 been able to plug and iPad or my phone into the USB port and bring it up in the menu under audio. In my current car I get my music off my iPhone under BT audio.

I had an 08, with the Aux jack, and I plugged a bluetooth receiver into it. I selected the aux input via the big Comand selector knob in the center console same as radio, nav or anything else.

Occams razor says the simplest answer is usually right, and I know this from computer issues. I know it seems unlikely but.

A) try another cord (I recommend headphone jack to headphone jack, rather than headphone to lightning or micro USB etc)
B) try another device other than your phone.
C) try another device, with another cord.

I dont think that jack is being seen by the system. Trying those things will tell you if its a hardware issue on this side of the jack. If those three things dont work, than you may have a disconnect at the jack level, or a head unit issue. But start there.

Please take a picture of the top menu after you select Audio.
I have an 09 with the Tune2Air Bluetooth...

Ok so it seems that maybe it's not plugged in somewhere, I plugged in an old iPhone to the iPhone port and it doesn't charge, anyone know where to check next?

Alex.currie44

Ok lets start over here.
Are we talking the E55 or a 2008 C63?
If you are talking about the E55 your Comand manual says you have a soft key to the right of the screen marked AUX.
With the device connected to the 1/8"pin jack in the console box push AUX.

If we are talking about a 2008 C63 you go to AUDIO on the top menu bar and go audio>audio and scroll down to AUX and it will appear at the lower left of the screen according to your manual. with the device plugged in.

MAKE SURE the volume on the device is turned up full. The input volume controls the output volume.

It's an 08 c63, I have gone through every possible audio selection and aux is listed nowhere

Alex.currie44

I can only guess then that somebody has changed the head unit. Try pushing the DISC multiple times as the W211 manual suggests.

604 C63

Have you tried the three things I suggested?

If so, you likely have a vehicular hardwear issue. See a dealer.

If not, there's nothing to be done until you have.
Im at work and my magic wand is at home lol.

Alex.currie44

Seems we are on the same page D. It shouldn't be that difficult.

On the 2008's, the iPhone port will not charge it is only there for playing music.
How did you get the other aux port in your glove box? Did you drill a hole?

QWKSNKE

So, using the comand controller as attached doesn't result in Aux?

604 C63

Some came with an aux jack right there in the glove box from the factory.
Mine did.

Alex.currie44

Correct me if I am wrong - and I have no doubt someone will - but I vaguely recall from my 2003 E the issue was the power is there in the adaptor but the 30 pin apple cables did not connect. If I recall you can get a more modern 30 pin cable which is compatible and it will charge an iPhone.

QWKSNKE

Cool. I had to drill a hole for mine. The cable was there but hidden outside the glove box.

I have never used it though. Need to route it to a more friendly location

cptncreme

nope, when is select satradio in the bottom corner it only gives me options for sat radio stuff. Audio shows everything as yours does, except aux

asaud7

Have you tried running the audio jack to a Bluetooth gateway rather directly via the phone?

Alex.currie44

Seems to me that perhaps this saga could end with a BT set of small speakers tucked away where they won't be seen. This is really strange.
Did you ever check to see if the head unit was the correct one and has not been changed?

So I have a UK ML280 - 2008 model. The jack plug is on the right hand side of the glove box under the CD auto changer

I found the way to activate it was by plugging something in then holding down the CDC ( cd auto changer ) button and this then says Input Active.

Took ages to find both

good luck
