Depends on where you live! BMW DOES have one they sell in many markets, but BMWUSA chose not to import it. My sister and brother-in-law are in England, and they sent me one...works fine. Took all of a few minutes to install...clean the surface with the supplied cleaning pad, then, stick it on! You can find it on the www.bmw.co.uk website, or most others around the world. It's available in a few colors from the manufacturer, but BMW only sells it in black (if I remember correctly). If you were in England where they're made, you can get them in more colors.
