Yep, you're right, the shade is manually-operated (I couldn't find any statement to that effect, until your reply). It was stuck to the front seal with headliner glue. I pulled, pried, and stretched it loose, then scraped-off the residue from the seal, and managed not to tear or tear loose the headliner material (though it does need some attention).

Also, there are rubber strips just above the cover (on both sides that feel somewhat loose), but I'm not going to pull on them, since I'm not going to use the sunroof, ever. Are they supposed to be loose?

Now, I need to find the tool to crank the sunroof open for the next step.
