Looking to close on 2008 330 EC soon. In checking boat over (numerous times) neither I nor my wife, nor son-in-law nor surveyor can remove this mirror. Seems to be super velcro'd on. We pull the single knob at the bottom till mirror starts to bow to the point we're afraid it's going to break. Afraid to slide something into edge for fear of cracking/chipping it. Is there a trick to this?
