Yeah, if I have the time!!
I have those same magnets, they are called neodymium magnets. They are supposed to be really strong. The thing was that I didn't want to mount them on the front, I was trying to mount them in the little ridge on the back of that trim piece. Once I did that, there was simply too much material there for the magnets to be effective. I also thought about drilling holes in the trim piece and painting the magnets black so I could flush mount them in the trim. Not sure if they would hold though and I don't want to destroy the trim piece for nothing.
Thing thing I like about my piece above, is that if I get caught in a rain storm, I can still use my GPS and such because it's clear!!
E-Bay right on down to 1/16 x 1/32
