Let's DIY aux input cable.

Great DIY! Nice diagram too!

Hi, i have made myself cable and installed it, but as yet have not managed to get it to work, can anyone help? i have the mp3 player playing but cannot find it when i cycle through the modes.

i am using a business cd hu manufactured 10/2002 which obviously has the aux on the back.
the software version is sv-40-02-510
i have the bmw cd changer currently installed

i made the cable from a 3 phono to headphone jack. i cut off the phono connectors and used the red and white as audio, and yellow as ground. Is this why i am not having any joy, i thought this cable would be fine?!? Help please

Hi,

I got aux input installed in my car but apparently I can't use the cigarette adapter while using aux mode. Any suggestions?

Edit: 12 amp noise filter... gotcha

Very ingenius!!
The information is great and the pics also. Thank you for the posting!
I'll be doing this installation soon on my '02 325ci



Vert

so I'm probably going to buy the OEM BMW cable. Does anyone know if it has the resistors/caps built into the cable?

According to the diagram it seems to have the components built in.

I've just ordered the parts, including the fly-lead to mp3 player for about £15 to make my own, not sure where the best position is to place the socket yet though.

I'm guessing the components aren't essential to use the input, the caps probably just provide some level of protection to the input and the resistor simulates a device being there so your "aux" menu option will show.

Purchased the cable from BMW and the Aux input appears without having anything plugged into the input. Works great!

That's what the resistor in the cable does, fools the HU into thinking something is connected so the AUX display appears.

2. Turn Radio On.
3. Press and hold the "m" button for about 10 seconds.
4. Press < or > to navigate, you will need to go to the 2nd screen to look for the SW Verison which is in a SV xx-xx xx format.
5. To be Sirius/AUX or XM compatible, the radio must be SW 43 or higher.
6. Turn radio off to exit.

The MODE button is not a good enough of an indicator to check if a radio is AUX or Sirius compatible. It needs to be manufactured 09/02 or later.

How do you find out SW version on business CD. Holding down my M button does nothing, apart from put it into Manual mode.

I have Professional HU in a 2002 model of 318i. And yes, I have the MODE button. SV 03-02 66 - is it AUX compatible?

arghhhhhhhh business CD version 40!!!!!!! spewinggg!!!!
would have made an awesom project aswellll....
... so whats my options now

ok if i read ALL of this right. for a 01 325i sedan i would have to get a newer HU if it doesnt not have a AUX button or i would have to get an interface to convert the Cd changer(which i dont have either) to an AUX port?

an the new HU has to be 09/02? and then i could make my own AUX cable for an i pod that could fit in the new rear HU?

One more qquestion...i have a chevy and i did something similar but as soon as i unplugged the radio(stock) security thrft system locked me out completly and had to contact GM to activate it again. will it do it on a bmw stock HU?(stupid question)

Aweaome DIY but im stuck with the non mode HU
