Attach the back brace to the CD/MP3 player using the supplied hardware. Then attach the other end of the brace to a firm mounting surface (i.e. Dash brace, fire wall, e.t.c.) This will brace the back of the CD/MP3 player to ensure solid mounting to prevent theft and provide optimal CD play.
Once the CD/MP3 player is secured, fit the trim ring over outside edge of the radio until it snaps into place. Insert the face plate with the right side first. Angle in the right side slightly then gently push the left side of face plate until it snaps completely in place.
