My silver Tiburon - which gets blown on Saturday, woot! - finally has tunes coming off of my Sony UMPC. I got my RAM mount today, chopped off 5 inches, and bolted it in. I like it!
I'll probably fill the base of the RAM up with epoxy or JB weld at some point - those set screws do a marginal job of keeping the mount from moving, but I'd prefer to cement that sucker in place.
