The Ford 6-CD player requires and external shipping bracket to keep the CD-transport in place during shipping.
After you remove the shipping bracket, be sure not to turn the CD-player up-side-down or the transport mechanism will fall off the mounts (That what the shipping bracket prevents). After it is completely installed there is no procedure to remove the unit from shipping mode. The shippin mode just parks the CD selector/head in a specific location where it will not be damaged by the shipping bracket. Normally the head and CD selector is located at the location of the last CD played, selected or ejected.
