Ain't sure how ur planning to wire the auxillary in but.. http://www.allenparts.com/cgi-bin/ford/ ... &NOLOGIN=1 That's what you would get if u got the auxillary option, its a simple retro fit. You pull off the front fascia, unbolt the 4 torx screws holding the stereo in, remove the stereo, unclip but don't remove the wiring loom, plug the aux cable in, re-clip the loom, and ur done! Fitted mine in about 30 mins, which included drilling a hole thru the glovebox for it to plug into it. EDIT: This is provided you have the CD6000, with the aux button on there.
