The control does look like a window switch. When the roof is closed, pressing the front edge of the switch and holding it for a second raises up the back side for venting. When open like this, pressing and holding the back edge for a second or two closes it.
When closed, pressing the back edge of the switch slides the window down and into the roof. Like the driver door window, this has an express open feature: a short push and release, and it slides open all the way. To close it, press the front of the switch and hold it until it stops by itself. (about 5 or 6 seconds). If you let go too early, it will stop with the roof half open.
To go from vent to fully open, press the back of the switch and the vent will close and stop. Then let go of the switch, and press the back again, and it will then slide back. Same thing to go from open to vent, just press and hold the front of the switch twice. Kind of a slick way to get two features out of one switch, but it does take a little to get used to it.
When you turn off the ignition, the roof stays where it was, just like the power windows. You must close the window manually before turning of the ignition, although the reserved accessory power will still let you close it (until you open a door).
The sliding sunshade is manual, there is a handle to slide it open or shut, alhtough it will slide back with the glass when you open the roof.
So far as I see, the only thing you lose with the sunroof is some overhead storage as the sunroof console is shorter, and a little bit of headroom. As a bonus, with the sunroof you get the HomeLink garage door transmitter, which is normally only available through the convenience package.
Did all that make sense, or did it raise more questions?
