DIY Help - CD Changer Installation

[X4.999]

I picked up an Imola Red 4.4 2006 with lots of nice options like DSP, DVD NAV but no CD changer. I found a changer online, using the instructions on this very site I'm stuck at step 6:

6. Locate audio and power cables in vehicle.

I see some cables that look like they are probably the right ones but they are already plugged into something - can't tell what, the wires disappear under the floor (so maybe they aren't the right wires at all).

Anyone been through this? I should note that it looks like this car used to have a CD changer - (bolt) markings on the paint where it would have been mounted. I'm guessing the dealer (not a BMW dealer) relieved me of the CD changer and put it in her own X5.

The instructions are here:

If they are used already then they aren't the right ones. You need to locate cables in that area that are specific to the cd changer. Take a few pictures and someone will identify them for you.

Here are some pictures of the cable area. I've done some more poking around and tugging and still no luck.

Just a thought but, if this vehicle had a sirius install, I believe the audio extension cables would have been extended from the changer area (your photo) to the spare wheel area....

I could be way off here but refer to the sirius install instructions for a good look at how the wires would have be routed from CD changer location to the spare wheel area, and back again.....

I removed the little shroud that the wires go under - they route through the spare tire area, seemingly towards the front of the vehicle. No sign of a sirius install to my untrained eye.

I'm starting to wonder if I need another part, the connection to the DSP amp seems to be a single wire connection, presently its from the DVD player. I don't know what's going to happen that will allow me to have two things going into that single connection. If that is indeed what I have then bimmernav.com says I need another part (wire assembly):

IF your BMW is equipped with DSP Audio system AND you have the single wire audio connection from CD Changer to DSP amp E39 P/N 61.12.0.140.718 (620mm) 6 wire CD Input cable ($13.12) E39
X5 P/N 61.12.0.140.716 (3000mm) 6 wire CD Input cable ($13.12) X5

But elsewhere on their site they say that an X5 of my vintage shouldn't have the single wire connection to the DSP.

Disclaimer - I'm not certain that the thing I'm looking at is the DSP and if it is, there is another connection on there - something plugged into it, looks like 6 wire but I didn't count carefully.

I think this could help you. one of the pics does show the 2 connectors you require.
