The CH-WSMB Mirror bracket is used with a dash monitor to enable this to replace a standard rear view mirror which have the common keystone shape mount as used in many models from Toyota, Mazda, Isuzu etc..
Suit will all dash mount monitors with a slide-in slot fitting in the rear but when being used in place of a mirror we would not recommend any size above 7″ with the elongated design CH- SMRVAHD73 the recommended option.
