The rear view mirror clam shell is held on by a few clips. It very easy to pry open and I was actually able to split it with my hand. But to be safe use a plastic trim tool and insert it right in the middle and give it a very gentle nudge and it will start to snap apart. I think the solar sensor is bonded to the windshield so you might need to take a razor blade to remove the harden glue. Just replace with new part. Please do a follow up write up once you have done this as I've only replace the Cond. sensor.
