Intravee II Installation help

[barryb97]

I have an 01 X5 with DSP, no Nav, no CD changer. When I went to connect my Intravee II I find two free iNet connectors but no analog input connector. There is a small coax but it is hooked up to something. I tried unhooking it and the radio still works. Do I need a digital to analog converter? It was so easy in my Z4. There is a small box (antenna?) installed up on the sidewall that has two small coax cables connected to it. I'm not sure what this does. I'm confused.

Where does the other end of the coaxial cable shown in the first photo goto? It's not likely to be the cable shown in the 2nd photo.

It looks like it goes to the module in the picture on the bottom left. But I can't trace it all the way without taking the side panel off. I did use an Ohm meter between it and the coax in the other picture and they are not the same line.
