2007 S80 Rear View Mirror
 

Just bought a 2007 S80 V8. The inside rear view mirror needs to be replaced. I found a replacement but can't figure out how to get the old mirror off. I removed the trim around the mirror to expose the wires. I've disconnected the wires but can't see how to remove the mirror. It looks like it is somehow attached to a base that is adhered to the windshield, How do I remove the mirror from the base?
