b.From behind the mounting surface, insert the shafts through the mounting surface.

c.Adjust the nuts on the shafts until the stereo's front panel lines up properly with the dashboard. Insert the supplied gasket if additional front panel support is needed.

d.Place another supplied nut and washer on each shaft and tighten the nuts to secure the stereo against the dashboard.

Note: To further secure the stereo, if your vehicle's dashboard space permits access to the back of your stereo, attach one end of the metal strap to the bolt on the back of the stereo. Then attach the other end of the strap to a solid metal part of the vehicle using an existing bolt or the supplied self-taping screw. This strap also ensures that the stereo is properly grounded.

7.Reconnect the wire harness and antenna.
