I finally bit the bullet and installed the smartTop in my '09 SLK350. It literlly took me under an hour start to finish, which included me reading the instructions

The install went smooth, but I did manage to break one of the canbus cover tabs. They are a bugger to get open. I left all of the options on factory default and set the speed setting to 25mph. I may also set the daytime running lights on with the fogs. Right now I'm just happy that the roof opens and closes the way I think it should from the factory. But I'm most impressed with the fact that ALL of the windows close when the roof closes, especially since the '09 lost this functionality. I never quite understood why the rear windows never closed even with the express up function of the regualr window function. Its not like a child would be sitting in the rear seat

and get their fingers caught. Oh well, I'm loving my car and heading out to enjoy the day.
