You should go to the e60 stereo forum.

The schematic doesn’t say what years it covers, but all the components match… and I took a photo of the amp in its location… unfortunately I got the BS split system…

Do you have a link to that forum? The one I posted in (from this site) is not getting any responses

You are going to have to do your own research to find 5 series info.
That link I put in the last entry is a 5 series board.
Also since that system was built by Technic(the one in the link) of Technicpnp.com I would suggest trying
to get in touch with him since he has seen all the BMW systems across
all the Series for the last 20 years or so.

This is in the no good deed goes unpunished area now

I was reading this on my phone and didn’t see the link you posted in the last response …(it didn’t show)

I’ll take a look


Thanks!! 😁

That link is perfect… they are discussing the exact stereo setup I have and solutions for it!!

Awesome!

The thread is old (like my car) but I’m going to read through it and chime in… hopefully there’s still someone alive over there… lol

Thanks again

Hey i was wondering, where does the Auxiliary USB port in the center console get its power from? cause the USB plug has no power and was wodnering what fuse provides the power to it, or if it get's power directly from the Head Unit. as all my other features are working.

tested the USB by plugging in phone and noticing no charging, so then tested with a USB LED strip that was working plugged into a USB A port and no light.

[ctuna]

As far as I know to have the center console usb active you have to have
the 6FL option that requires a Mulf 2 hi or Combox module in the trunk behind
the US rear passenger seat under the floor of the trunk in a non convertible .

I don't believe it is fused. The Mulf2 Hi or Combox may be fuse though.

You bought it used you need to find out what it came with .
Use mdecoder.com
Then check for module in trunk.

yes it has the 6FL code.

i figured there would be a fuse, as most i see with USB down also have the aux in port down as well, but my Aux in 3.5mm jack port works fine.

would be nice to have an accessible wiring diagram ( thanks BMW AG for being a prick) so i can at least see precisely what colors go to the USB port so i can circuit test for opens or shorts, and know which pins specifcally are set aside for it on the MULF.

the car does not have the COMBOX upgrade, it's the standard telematics/mulf/satellite/idrive, with the harman becker L7 optical amp.

There are pin-outs for the Mulf 2 Hi online.
And the retrofit threads cover this to.
If you have IstaD for diagnostics (highly recommended)
it has the pin outs and wiring diagram's to.
Ista D is like having a shop manual with guided troubleshooting
for just about everything and schematics and illustrations to.

If you just do search for Mulf 2 Hi BMW on the open web
a lot of stuff will show up .

The usb has it's own Fakra connector.

This above has the pinouts for the Mulf 2 hi and combox.

Man i've tried to find a link for ISTA, and it seems everyone with access is charging now. Bimmergeeks had their mega access removed, and NewTIS was hit by BMW AG cease and desist.

and thanks for the link. appreciate the assist.

The console USB is connected directly to the COMBOX. It is for data only and will not charge a phone or power any USB accessories. I have heard of a USB hub that comes in some cars that may be able to provide charging power, but not much regardless, maybe 500mA of current.

I think you're thinking of the CCC setup, where as mine is CIC, there is a telematics and the MULF, also the USB should provide some power, otherwise the Bovee BT adapters people are using to avoid the expense of converting to COMBOX wouldn't work, as they get power from the USB port. in addition, anything plugged into my console USB doesn't work or show up on the iDrive display, so my USB box according the the combox conversion may be toast from the look of things, as i have no codes for a failed MULF, and my MOST fiber all works. or it is unhooked somewhere, and i don't feel like ripping it apart ATM, or removing the rear seat backrests cause mine doesn't have fold downs. so it will be a future project, i was hoping it was something simple, like a fuse.

but then again i should have known it would have an intermediary as USB is a 5 volt plug on PC's so any USB accessory would only function with a 5 volt reference, and cars are 12 volts, so a bit of a derp oversight on my part. as of right now i'm putting this on the "to do" list, but it's kind of at the bottom as i am using the accessory outlet with a USB converter to power the BT adapter for aux, and charge my phone. ( yay workarounds!) and getting factory suspension back on it is top priority right now.

This would apply regardless of TCU/MULF or COMBOX. It's the 6FL option that adds USB to the armrest. I just converted two cars to CIC from CCC and one had the 6FL option. All that was required on that car was to move the pre-wired USB FAKRA cable from the MULF to the COMBOX. The car without required running the one cable from the trunk to the armrest, for this purpose. Post conversion, with all functions working normally, neither car will charge my phone when plugged into the armrest USB, because that USB lacks current.

Yes, that's the 500mA I mentioned, enough to power something, but not provide charging current. Voltage and current are two different electrical animals.

I would check either the COMBOX, cables or coding, any one, or all of those, could be at fault. COMBOX has to be the BN2000 version not the BN2010 model. It is also re-pinned to the 26 pin connector from the two TCU/MULF plugs, which could have gone awry. Or if using adapter cable the adapter may be bad.

TTL is 5V, so there is lots of regulation and conditioning from 12V to 5V going on all over a modern car. The COMBOX is responsible for providing the 5V to the USB port, so provided it's all coded and wired correctly, could be a bad COMBOX. Again, the cable from the trunk to the armrest provides the connection, but does not have the 1.5A you will get from a computer or port designed to charge a smartphone.

[Podunk]

I think there is something getting lost in communication, i have not converted to combox, and probably won't be anytime soon, as getting to the MULF is a major PITA when the seats don't fold down, so i'm still on MULF/Telematics, instead of All in One COMBOX

As for coding, i used Bimmergeeks protools when i replaced the L7 DSP TOP Hifi Digital media amplifier, and verified the codes for 6FL are present, and pretty much ran down the list for coding just to make sure i hit the amp, cause i wasn't positive which part of the system it is, i am thinking M-ASK, but in all other instances that refers to the head unit not the amp, so i don't know. but at least I have sound where i didn't before.
