I have a 2010 HONDA CIVIC EX-L model & did a custom install of backup camera monitor on my factory mounted rear view mirror. The backup camera monitor is designed to be clipped onto rear view mirror. but the problem is, it is becomg too heavy & the factory mounted rear view mirror is not able to hold it & slides down always when the car is moving & I cannot see the back of my car..what should I do now ?? I bought that from Internet & since it is more than 30 days now, the company which sold that product does not want to do anything .. The product is made by VALOR & the model # is RVM-600W. Can anyone suggest a solution to the problem ??
