It must be up front because the nav 4 is suposed to be able to plug into it .the nav 4 has 2 plugs on 1 for power other for audio on new radio so must b near that plug. I can't see it either

 

If you find the right plug will this give you the functionality you want, or will it be a real pain in the neck to switch between the bike's speakers and the Autocom headset?

If you "just" tap into the bike's speaker wires using an Autocom switched lead you would only have to flick a switch to swop between speakers and headsets, but I suspect it will be a number of button press / scroll wheel movements to do this via the additional speakers route.

Please let us know how you get on, at some point I will get a 2010 and have the same issue!

 

The switchover is easy to do via the display takes seconds finding the plug is another matter. The manual for the nav iv says that it just plugs into this conection and also the bike radio manual says the same.After you plug the power lead in the only place that the other lead will reach would be behind the dash.
I think when this is sorted this will be the way to go you only then need 1 lead to the autocom.If you plug your sat nav into the radio line in it will reduce the volume same as the autocom and you can change tracks from the controls on the bars on the ipod.

I GIVE UP..

I cant find it, The dealers expert cant work out where it should be and the Factory expert said its in the back near the rear seat lock but it’s not... ??

Have you guys removed the dash panel which gives you access behind the speakers? I know the secondary horn connector is taped up on the frame by the left speaker and virtually imposible to access without dismantling the dash. If you don't already know the dash is very easy to dismantle.

 

I have now passed this one to BMW UK via their customer service department.

I just find it amazing that they have built a bike, produced user manuals, technical manuals and training packages that all refer to the four-pole line out yet despite photographs showing where it should be no such plug can be found on the bike ?

Once I get to the bottom of it I shall update the forum because I cant be the first and I won’t be the last to want to route the radio audio into a helmet headset surely..

Well for those out there who have been waiting to hear the result of this quest, the bad news is your still waiting ?

After getting nothing short of the brush off and very poor service from Customer Service at BMW I have escalated this enquiry to the head of Tech Support in the UK who himself has been unable to answer the question ?.

He has now taken ownership of my enquiry and passed it through to the designers in Germany !

Watch this space.

 

:think: looking forward to solving this mystery.

 

I am facing the exact same problem here in Greece. It seems that no-one on the service team have the faintest what is going on. The illustrated four-pole connector in the manual (by the way, I own the German version...) refers to the wiring harness of the navigator iv and was inadvertedly included in all manuals.
Anyway its a no-joy (for the moment) from the team in Germany too (the keep sending us extracts from manuals with the same mistake persisting (they all refer to the 4-pole connector, the holy grail).
I have requested the circuit plan for the audio electronics. It seems that we have to dig under the right hand side panel, below the compartment with the USB connector, were all wiring to front and (hopefully) back speakers originate. Theoretically we could tap into the wiring there. As soon as I have something I'll post it up here. Please do the same.
Cheers

Hi Ipilot, sorry this is not a reply to solve your problem, I was just curious to where you are in Northwich I too live in Northwich Lostock Gralam, I will be getting the 2010 model next weekend all being well, what do you think of yours so far, apart from the elusive plug

Regards Frank

Hi Frank, It was only when you asked i realised I had not updated the site because i moved a couple of weeks ago. I now Live in Preston but I was in Lostock Green.

Site Now updated

 

Thats a shame mate,how are you liking the 2010 RT? did you have the earlier model before

No I had an R1200GSA before the R1200RT. I prefer the RT for the motorway work that inevitably comes between the twisty bits

I managed a trip to Devils Bridge today without getting wet which is a trick in it’s self given the easter weekend weather lol

 

Hi All, I replaced my 2008 RT with the new one wit radio and was hoping to be able to connect this radio to my helmet rather than being a moving boombox. I am very curious if anyone finds the 'lost' connector.

 

Hi,

I also own a new RT '10 with radio and I have asked my locale dealer (in France) to find a way to connect the radio to my helmet. Indeed, my helmet has two Koss speakers inside with a simple 3,5mm plug. I used to connect an iPod to it with my previous bike RT '05 (no radio).

My dealer has asked the french BMW HQ and they said an interface will be available soon for connecting to the mysterious-rear-speakers line out. I'm waiting for fresh news and will let you know.

Note that from the radio, yes, we can fade volume between front and rear and at full rear nothing is audible. At least, radio manages 4 speakers.

The last thing I wonder is the line out. Is it amplified enough to simply connect to headphones? The manual states "active" speaker can be added, no passive... I presume this is not an issue for who want to link an Autocom but what about headphones, helmet speakers? So many questions...

Regards,

Fitting the extra bits will be ok but first we need to find this plug to fit them to,I am begining to wonder if it exists

 

Ok Guy’s I can’t say how accurate this information is but it came from BMW UK who at my request obtained it through the Factory in Germany.

They are now saying the line out for the rear speakers is located behind the right mirror as they have circled in the picture they sent me (can’t work out how to post it here.) If anyone has time to check before I do please let the rest of us know what you find, maybe with pictures ?

Well I think this is the line-outAttached) and all I need to do now is figure what plug fits it so i can make up a fly lead to the intercom.

Assuming thats the correct connector the fly lead part number appears to be 611655.

Well I have hit another brick wall with BMW. They agree that the pictured connecter is the audio output but now they cant tell me the correct part number for a pin plug to connect to it.. BMW really are useless !

They probably don't have a part number yet. My dealer is saying there is no part number yet for the new windshield support arm.

Hi iPilot. If I am not mistaken, a closer look on the second picture you posted indicates that only three out of the four poles on the plug are hot. The fourth does not seem to have any copper on it. This should not be a problem though as a stereo connection only needs three poles (two positive lines one for each channel and a common negative).
Have you checked that the connector you found (I assume you did find it) is indeed the line out?

Yes you are correct it is a four pole plug but only 3 are used because it has a common ground. I have what we 'believe' is the correct connector on order and once it arrives we are going to connect up a pair of speakers and see what is actually presented

Thanks for the reply.
I will be performing some digging myself over the next weekend and I will try and test the connection with a multimeter.
If in the meantime you get your connector, pls drop a few lines for me.

Cheers.

 

Dear all. The line out connector is exactly were iPilot's pictures show. Right next to the RPM meter and you need to take half the bike apart to reach it.
Anyway it works. All of you who have had some elementary experience with a soldering iron and a couple of screwdrivers (or should I say torx screwdrivers to be more precise) can make it work pronto, otherwise you should wait for BMW to come up with the proper connector, if they ever do. They gave me a connector with part number 611656 which is not the correct one. Anyway, I'll give a short description of what needs to be done and ... the decision is yours!

The first attachment shows a close-up of the connector - although its a four-pole connector, only 3 leads are live - and I have marked them 1, 2 and 3.
Like I said, BMW are still searching for the right connector and I need my music now, so I cut the connector and used the cables behind it. The cables on Poles 1 and 2 carry the signal (left and right channels - makes no difference which is which, the bike does not have a left/ right balance switch) and pole 3 is the ground. For those of you who decide to attach speakers (although I have no idea where you could attach them - maybe the top case?) you should bridge the two negative leads from the speakers and attach them to the ground (pole 3) and attach the two positive leads to the leads on poles 1 and 2.

If you need to connect the line out to a communication system like Starcom1 (or Autocom - they are both under Tecstar in the UK) you will be needing a cable like the one shown hereunder. The 3.5 mm jack goes to the music-in of your system and you need to connect the four loose leads to the bike. Here's how you do it: First of all ignore pole 3 altogether. Do not connect the two negatives to it. If you do you will get a lot of static through your headsets. At least that was the case with my Starcom. It seems that as Starcom is already connected to the bike's negative (ground) doing it again through pole 3 causes static. Just solder the two negatives together and let them be. Then solder the two positive leads of your music cable to poles 1 and 2. That should do it. Naturally, take extra care to insulate everything.

Also, make certain that the line out is activated (press TONE repeatedly until you reach LINE on the display. If its off, toggle it ON by pushing the rotary volume switch towards the handle bar) and that the fader (press TONE once more) is allowing some throughput to the "rear speakers".
Enjoy!
