onebadmofo did mine recently... 10min and few bucks later (tip) I had the following:

- auto tailgate close w/keyfob
- welcome light now include fog lights with alarm disarm/unlock and comfort access
- all disclaimers gone (idrive boot up and backup)
- euro blinking hazard lights (double blink, pause, double blink)
- dvd movie in motion
- power folding mirrors on arm/lock w/keyfob (and unfolds when disarm)
- open and close windows/sunroof with keyfob
- rear fog lights work tandem with brake lights (makes a huge difference)
- digital spedometer in dash (lights up in same orange color)

everything works and i'm loving it... this guy was very professional, quick and he's done hundreds of them... he even spent time going over and testing each feature to make sure you were completely satisfied... and for much less than purchasing any equipment and having to learn at your own risk.

if you're anywhere in ny look him up... it's worth the trip.
