I've got my XM Roady2 ant. stuck to the rear view mirror stem, and it works great! Reception has been 4 bars (max) for months. No dropouts. I didn't want it on my paint or dash. It's hardly noticeable. The horse on glass doesn't effect it at all. Hope this helps somebody.

 

Thanks for the info, I'll be transferring mine from my 88 to this one this weekend. I'll try it your way.
