Some aftermarket audio gear, I'd guess, like a Bluetooth mike. Do you have an aftermarket head unit? If so, what model? Factory rain sense wiper sensor is a round patch just to the driver's side of the windshield up there.

Maybe a gps locator or an xm/sirius aftermarket antenna?

I'm with you. Looks like mini coax which i think is used for either of those 2 things.

The onstar unit under the right rear seat has 2 coax cables so I'd say one cable goes to the antenna on the left rear glass and the other cable goes to your picture.

That's possible, this would have been an analog onstar unit, which would explain why i don't have it.
