1st remove the factory radio cover.
Secure the Kioti mounting plate with the 2 screws that were holding the factory radio cover on.
Next insert your new radios sleeve thru the mounting plate into the opening and fold or bend the tabs to sandwich the sleeve to the opening.
Notice the factory rear bracket.
Slide your radio in the opening and you will feel the friction as your radio slides between the friction bracket. Your radio is now secure.
