Reversing Camera Monitor

Hi. This is my very first post and hope I'm in the right place!!! I have a Symbol which I adore travelling around with the dog discovering new places and relaxing . However I had a reversing camera fitted from the dealer, coupled with a clip on the rear view mirror monitor.  It works a great and I really do need it as a lone driver. But this year the mirror came away from the windscreen, monitor and all.  I've tried all sorts of glue, sticky pads.  The mirror holds itself fine, but the weight of the monitor just pulls it away, some right off and some hanging precariously.  Has anyone else found this problem and how was it resolved?  I'm thinking of trying to mount it above the windscreen, but have no idea where to start, is there a bracket out there or even a block that the monitor can clip to which can be attached.  But I'm struggling where to start of turn for help.

There is a special glue for gluing mirrors to windscreens
Any of the windscreen replacement guys will help you, they have to re install the existing rear view mirror to a new windscreen.
Try local Autoglass or similar.
