Thank you for all the feedback... OK, well since I am new to the forum, I did not know anyone replied back to me. I hope this message reaches all of those trying to help me and by the way, I GREATLY APPRECIATE EVERYONES TIME.

Well, here is the deal. I am trying to install an aux input for my daughter's dvd player. FM Mod sounds bad and in some areas, does not work. And of course a plug for my ipod.

I called BMW and asked told them I had an 02 x5 which I would like to add an aux input. The part the dealer sold me looks to be the one for 03 and up (after doing some research on the internet).

I did some research and found out that it needed to be pluged in to the radio unit at the rear of the car, as stated in a reply above. However, per instructions, I pulled out the spare in the rear of the car, took off the plastic cover only to find a budle of wires and harness' that lead no where, just hanging there. So I am guessing that the Radio unit is at the front of the car. However, I do not know where and how to plug in the aux input.

This is my first area in which assistance is needed.

I also have a 6 disc changer in the center console under the flap that comes up. Holds 6 discs, but does not work. Also, I have an in dash business CD player. Business CD works, but chager in the console does not. Funny how the changer is not in the rear of the car.

The 6 disc changer I can live without, however, it would be nice to get it running since it is there. But as stated, one thing at a time.

Thank you to all who replied.
