Rudeja has found out that the connections where the BMW OEM Aux input go are active when the Radio Mute is active. Ofcourse this is only for people who do not have the OEM Aux set-up.

So now you don't have to get the expensive AUX wire or the programming from BMW. All you need is a simple female mini-plug or RCA connectors and connect them to the back of the CCC/MASK.

On the plug X13813 connect :
- Right +ve to PIN 7
- Left +ve to PIN 2
- Groun -ve to PIN 8

Then connect a simple switch that will Ground Pin 10 of the X13812 - This will mute the Radio and allow you new Aux to pass to the Stereo.

Also by doing this yourself you don't need to modify the BMW OEM cables to remove the Resistors and Capacitors that most people have cut out, you simply don't connect them. Just use straight wires connected via some Tyco contacts.

I don't know the exact part numbers for the Tyco contacts but they should be pretty standard. Don't quote me on this but part no 61130005197 should do just fine - it also comes with a bit of wire attached to it too.

I wish I know what you know. :thumbsup:

Well now you know too :D

you and fred (my530i) are the electrical genius here.

Hi Bruce,
does this apply to the M-ASK ? I don't have any form of oem nav in my car.

Thanks
FS

Yes it should be the same for the MASK too.

Very cool. Has anyone tried this with an iPod? I also assume that the volume control still works when the radio mute pin is grounded.

I feel comfortable with doing the wiring, how hard is it to remove the radio and get to the wires?

It should work for the iPod too because the volume is functional with the Radio Muted when Rudeja uses the input for the phone.

Yes the volume works when the radio is mute, I am really enjoying my BT upgrade, this is one of the best mod I have done. it should work the same for an Ipod.

Can't wait to hear. If you are willing to pay postage I can send a BMW OEM wire with the 3 connectors attached to them that I think you need. I'm not sure they are the ones but I have them in the house and its well worth a try.

Thats a great option.

I wonder if the bluetooth unit will fit in the ashtray, for a clean look. My buddy installed aftermarket sat radio in is 335i and the unit fit neatly in the ashtray area, just close the cover you see nothing.

Bruce, I think you just answered what my next forum question was gonna be - if the corresponding holes in the 12 pin (right) connector where these in/outputs are located are vacant, a Tyco contact is the way of populating them?

Cheers,

Ian.

I remember losing bass on other sources if you install the AUX without programming. Actually I'm pretty sure that you do lose bass. Thats what happened on my 525i before. The dealer put in the AUX cable but didn't get to program it right away, so I had to come back the next day, and drove around for a whole night without bass, and the dealer said that its suppose to be like that, and that i"ll get bass back when programming is done.

But with the Aux wire you would not have been grounding the Radio Mute button so that could be the reason. Also without the radio muted, you would have two source competing for the same amp and that could be the reason for the lack of tones.

Great read up :) on both of your mods.. Nice work

Ok couple of questions..

I am intrested in doing a Bluetooth and AUX

Now for AUX I would follow your instructions above
and for Bluetooth it would be pins 6+ 12 + 10

Now my question is as both need to connect to pin 10 what will happen when say you have a mp3 connected to AUX and a call comes in ? will it have both on the speakers until you flip the switch used for AUX to just have the phone alive?

Lastly the Tyco contacts and wire where can I get those from, maplin? or I can pay your postage costs like you offered AlwynMike

Thanks

Also I forgot to ask was you was pin 10 to switch to ? how do you control it to mute the radio ?

I might have to try this on my friend's car.
He has an 04 and he says there are no aux inputs so I might try this one for him.

Sweet! Has anyone tried it yet though?
And what are and how do we access the CCC/Mask?

tried it. big waste of time and money. poor sound quality and sound only comes from front speakers.

Shucks, I was really hoping for a way to avoid dishing out money to have a dealership do it

Sorry to bring up an old thread but I remember I had a solution for this..........

I believe your front speakers are only working while doing this due the following:

Plug X13813 is already attached to you M-ASK/CCC's X13812. If you buy the OEM Aux kit you are paying $60 and it is also attached to a X13813. If you plug X13813 into your M-ASK/CCC you are disconnecting your rear speakers and the shallow mount subs under the seats.
If you cut the OEM Aux cable and use it and tap into your existing X13813 you should have no issues with sound. Likewise you do not need an OEM cable, any quality aux connector such as: (http://www.sonicelectronix.com/item_...N-MINI-2M.html) will work. Monster is good but I don't know if this fits iphone/ipod. If it does work then proceed.....Splice off an end and wire it in! Chances are you have several of these laying around the house.

Again sorry for reviving old threads but I hope this is helpful for someone else should they need it.

Can you help out with the mute function? I took pin 10 in this diagram to ground and it does not mute. Is it dependent on the radio/year? Mine is 2008 Logic 7.

You've got a working NCS set-up why are you even bothering with this. Just add the proper AUX-IN yourself into the CCC.

I'm actually doing something else. I have a custom installed radar detector that provides a mute signal (ground). When my detector alerts, the lead will go to ground.


So I was testing whether I could get the radio to mute by grounding pin 10 and it doesn't seem to work.

If you have AUX-in already coded then this may not work. However look in the CCC trace file there are a few options relating to the MUTE. Try those.

Man, I just wish I knew what you Geniuses are talking about... https://5series.net/forums/public/st...t/confused.gif
I guess I'll have to wait until someone breaks it down into layman's terms.

I'm currently using the AUX in the rear of the armrest/console. So... what's the advantage/difference hooking up my iPod your way?
(Sorry for asking -what may be- a dumb question, but I've just been starting to test the 'modding waters'... https://5series.net/forums/public/st...t/original.gif )


Thx!

im interested in trying this out on my 530 but i was wondering if the radio is "muted" and i have my iphone playing music will it switch to "unmute" when i get a phone call through the idrive?

This is a very interesting thread. Bruce, You've done amazing work to your BMW, I enjoyed reading some of your MODs in your signature.

I have a 2006 530i with factory nav. and 6 CD changer in the glove box, and Logic 7. I'm very interested in adding the aux. , the dealer here wants $450.00 to do this simple addition. Would this MOD work for me?

I have the same question as MDOT above. I use my iPhone through the car's BT all the time, would this have any effect on the operation?

thanks much,

Serv

Tried this today on my 2005 545i non-nav. Unfortunately I found that when I ground pin 10, the aux input on plays thru my center dash speaker. This would be fine for a phone, but no good for music. On the bright side, I am now wired for aux with a DIY cable, just need to get the stealer to turn it on. FYI - I did not find any change to my CD or radio sound with these wires in place even though the aux is not configured, so I zipped it all back together to start saving my pennies for the download.

Hahaha, same here! How many different radio systems are there from 2004-2010, and which ones will this mod work with? I have a 2006 530xi w/o Nav, w/o CDC, w/o AUX. Will this work in my car? I'm also in the same boat as Serv, where my Android phone connects to the car thru BT, will it affect the BT function of the car?

Bruce, what type of switch do you recommend? Unfortunately, my electrical engineering knowledge is a bit limited and there are so many different types:

Any particular specs we should consider?

Would either of these work?

Sorry, waited too long to edit :/

There are so many options, not sure where to start?

Same-same,
2006 530i, Logic7, NAV, 6-Disc, BT phone...and single CD/mp3 playback DOES work. Looking for 'simple' iPhone hookup (AUX? I have no use for 6-disc changer)

-Tone

Hi. I wired the aux plug onto existing x13813. But the sound still plays only on the front speakers and very poor sound quality. Please help.

wrong thread..

I installed a BMW ipod interface and all i get on the ipod is 'OK to disconnect" what did I do wrong? My 06 E60 plays MP3 and i have an AUX installed.
