On top of the gas tank on the right side. If you take the top plastic off you'll see it. About 4" diameter. The Icelink module fits - barely.
I ran the thin cable to the Ipod dock into my Chicane bag. I plan, Like Joe Messinger t run it through the handle bar and mount on the RAM mount that Raffey sells that takes the place of the Clutch resevoir cover.
Depending on how you end up with the Ipod/Icelink setup, you might just want to put the Ipod in the glove box. That's another option i'm considering as I will be safe and dry.
At this time, I've ended up with the Icelink only controlling FWD. The Ipod can be controlled by itself. This is kinda nice as I can move between Genre, Albums, Artist, and Playlist. Bad, in that I have to have it in the open or in the Chicane map case. Bad that I take my eyes off the road to change....
