I have the xm commander installed but I didn't mount in on the dash. I have it sitting on the drivers seat edge up against the center console. It's not mounted so that I can hide it under the seat when I'm in areas where I don't want anyone to be tempted to do something stupid. Seeing the display is a look down process and certainly not the safest thing to do while driving, but I generally stick to one channel and listen not look at every song/subject.

It's just a pity to clutter a nice looking dash.
