Hi all - Haven't got around to my install yet and I'm pondering the thought of getting a double din w/navi. Thinking of the Pioneer Avic F900BT. I can't seem to find if it has time alignment or if you can go active from it like the 880PRS that I have now, and , if it can go active, will it have the same / different x-over section like the 880? Any thoughts one way or the other? Thx.
