I placed mine in the useless compartment under the a/c controls. Just made a cutout in the facia of the lid. Bolted it thru so it's pretty secure. Angled it upwards to see a little better. I think it looks well integrated. I'm not too found of stuff sticking out everywhere. If you search you should find a picture of my instal somewhere. I haven't access to my home computer with my pics at the moment so can't post any right now.
I love my Sirius!
The search bares fruit
