Somebody is getting rich...
Works for the most part; not the most attractive thing to hang on the dash; and $50 for a piece of plastic?

Sun shade
Nice fit, good looking

Radio Shade
Shad works as well as can be expected. It shields much of the daytime light out, except when the sun is directly at your back

2.5 Mega Audio Shade
Works great! Slides in with ease.

Sun Visor
The sun visor is awesome. It definitely keeps the bright sun off the screen so you can read it.
