I never knew it had anything to do with the tape deck .. haha ...
As per my post above, my family and I have had four cars with four different renditions of this tape deck (my PGT and my dad's '93 Taurus had the electronic eject; my Contour and my dad's '98 Windstar had manual eject, etc) and all of them used Seek-to-Tune when pressing AMS.
I wish I had known this when I used the tape decks; it would have made skipping songs a whole lot easier
