I don't know for sure but I don't see why a headrest from an earlier Jetta wouldn't work. I don't understand though, is the problem that her head is tilted too far forward? Try tilting the seat back. 2005.5-2006 Jetta had active headrests which moved forward and down. 2007-2008 had passive headrests with a lower whiplash rating. 2009+ had passive headrests which were tilted forward and have the best safety rating.
