Hi. I got a 2007 last August. I think the '08 work the same. There is a "hot" section on the tailgate to open it. It's a bit finnicky but it works. I love the
Comfort Access.
As for the Sport and Technology package I ordered neither. I did not care for the Technology package and find the Sport package to be kind of an anachronism for this beast. Besides, in itself the X5 is plenty fun to drive. I also will be getting a Z4M Coupé in March so I'll get my Sporty kick with the
Z4. The X5 is my hauler, a rather impressive one at that.
As for the NAV system I have seen none in any car makes that could match a Garmin product, especially for the asking price.
I am canadian so the Sport and Technology packages may differ in the U.S so they may be more interesting.
Enjoy your X5.
