Pinouts for eject box 84.10.9.168.940

Hi All,

I'm trying to get the pinouts for the "new" e46 eject box.

The old eject box had 4 wires.

1: Green (pair)
2: Brown (gnd)
5: Red (+12v)
13: white (Cradle on)

The new eject box

1: Purple (or violet)
2: Brown
5: Red
13: Green
14: White
17 Yellow

Any one have any ideas?

TIA

John

I would suggest the extra two wires are the USB. But I can't be sure. The WDS is particularly useless in this area.

Thanks Bob, I had a feeling they extras might be that, but as you say the WDS is useless.

I would be surprised if they are unmodified 5V/0V USB. Unmodified 5M+ USB runs are pretty dodgy for reliability, and I doubt BMW would use such a system.

I'd wager there is a line driver, probably 12V and perhaps USB 1.1 to keep EMI emissions down. USB2 is like 480Mbps so 450HMz+ via unscreened cable would be a problem.

Is the 18 pin socket the same for E60/E90? I seem to recall white & yellow are used for USB in those cars, but the memory is a bit foggy.

Are you trying to hack iPod audio through the cradle? I am just now looking into that. I have the iPod integration already and Bluetooth, just trying to put it all together in a nice cradle with antenna. Surprised that's afterthought for BMW.

It was for a different project, however I have done just what you are asking... albeit for the Intravee and alpine KCA-420i

Here is a copy of the write up I did:

I've managed to get this done.

Connected it up to my car and its all working as it should, tested with ipod and ipod touch (I don't have an iphone to test it with).

The whole process is reversible so you can revert the cradle and snap-in back to OEM.

The long and the short of it is that:-

The snap-in and cradle both need to be modded.

You need :-
The iphone snap-in,
The cradle,
1 x 30pin iPod dock extender lead,

Tools:
A soldering Iron,
A hot glue gun,
A small torx screw driver,
A small phillips screw driver,

You need to remove the gubbins from the cradle (easy), and the gubbins from the sap-in (also easy).

The snap-in's OEM male dock gets replaced by the male extender dock plug (once stripped down), the dock plug ends are identical and you need to move the metal shield from the OEM dock plug to the extender plug, it then is plug and play into the snap-in.

Stripped down Snap-in

Stripped down Cradle

OEM snap-in dock

Extender dock

Close up of extender now in OEM location, the antenna needs to be un-soldered and then it can go back together

Put back together

Gubbins removed from cradle

Pass the lead through the cradle hole (it fits), I also did a touch of hot glue to keep the extender lead fixed to the base of the cradle.

In car

Ipod touch with no charging, it sits on the home menu when connected. (and give the no charging message)

Display

I had a spare BT cradle and bought the ipod snap-in (cheap), I was bored and wanted to see if it was possible.

Adding the BT pair button and the antenna is do-able (if you don't want to make it reversible), but that's an easy fix.

I doubt I'll use it TBH.
