Usualy to find out what's playing you can just listen for a few secconds. The real problems arise when you want to find a song or go through menus. One hand sheilding from the sun, and another pressing buttons doesn't leave much to steer with.

I have this sort of problem enough with my sunroof that I do feel bad for you guys with convertibles. But then I think about it and realize you're driving around in a convertible on a sunny day with the top down, and don't really feel your pain.
