Adding AMP to 2004 X5 3.0d

[pratters]

Hi All,

I picked up my 2004 X5 3.0d a couple weeks ago, I now am looking at adding my aftermarket AMP and sub. There is plenty of info on the net for tapping into the factory amp, however in Australia and I think Europe There was an audio option labeled "stero" I believe and is non-nav, non-dsp and the amp is integrated in the head unit.

I've had a look around and can't find an alternative, does anyone know of any audio cables in the boot area that I could use in this scenario. I had a look around under the spare where some had reported a radio module being installed for some models however I didn't have that but thought maybe some cables would be there. The only thing I could find was down near my my PDC module and trailer brake was an unused connector, however I have no idea what it does and if it's audio related. I will attach pictures so if anyone could have a look and has any info it would be appreciated!

Thanks,

Ash
