This tray replaces the air vent on the top of the dashboard. The dash vent is a nice feature but rattles incessantly. My attempts to fix it have slightly reduced the noise but not stopped it. This tray removes the source of the rattle and provides a nice little tray to store stuff in. It only takes a few minutes to install. Follow this DIY here.
