Tribeca B9 Nav system in the WRX

[chimchim]

So the 2006 Tribeca/Legacy has a nav option... anyone know if I can get this for a 2006 WRX wagon?

Shouldn't I be able to buy the part option and have the dealer install it? (or install it myself)

And with the exception of maybe the bracket for the GPS pickup, it should be a bolt on?

(are the harnesses different?)
