Looking at this site and wonder which Dension Icelink i shld get: the one behind radio or the one for the trunk.

I have a B5 S4 with the Concert Bose with a changer in the trunk.

I also wonder if it's possible to just use the Dension icelink with a connecting plug only so i can place it somewhere underneath the armrest, instead of have the mounting bracket sticking out on the side of the center dash.

Help appreciated...
