These CD players will plug into a Ford Sync-4 USB data port and allow control of the music through the steering wheel buttons.

After you plug it in, tap "Audio" on the Sync 4 screen, select "Sources" and choose the "USB" to begin playback. Allow approximately 30 seconds for the system to index the CD before trying to navigate tracks.
Finally, make certain that you plug the player into a USB port which is not power only. (Certain USB ports in your Sync 4 are power only and do not support a data connection. Owners manual will show which. Believe that they have special markings to tell you power only.)
