How is the M535 alarm unit mounted?

OK, thanks, so probably nothing is missing. I'll take a second look.

I can see both the retaining tab and the screw head in your photos, so everything should be there....

Good eyes, nothing is broken, they just didn't replace it previously. Now it's securely mounted.
What is this handwriting on the unit/? Could it be from the factory? Or it was repaired at some point?

Does that number look like part of your VIN?

Nope, no match. What does that tell you?
