I just bought an 06 FEH & it has the POS factory NAV in it.
I say POS, because I have this setup:

in my 05 FEH & it's awesome & I'm not sure I can live with the limitations of the factory setup after being spoiled by the Eclipse unit(it's made by Toyota/Lexus)
If I remove the factory NAV & CD changer, is it worth anything to sell???
I think the Hybrid display is kinda cool, but not really necessary(I could live without it) & I use my NAV an awful lot & want the awesome screen/features of the Eclipse more than the Hybrid display.
