Can I add Cruise Control to my X5?

[X5Cat]

... and is it worth doing so?

I am wondering about the feasibility of adding cruise to my 2009 X5 (just purchased yesterday). I feel like such a dope 'cause I assumed that what was a $60K(?) vehicle when new, with panaromic sunroof, all this digital stuff, power seats, luggage rack, etc., etc., would certainly have cruise control. Could I maybe just be overlooking the buttons for it? My pedal foot is so spoiled by having cruise that I can't imagine taking this vehicle on a road trip of any length without it. If I can't find some reasonable way to add it, I'll be putting this thing right back on the market. Advise, please?
