i see april listed as when the 920 and add-on navi are released, is it the same for the rest of the 2010 line-up?
i am very interested in a AVH-4200 with the add-on nav. assuming they fixed the 24 hr only clock on the 4100 and possibly upgraded the EQ.
Could you buy an extra wire like one of these from, say, a computer supply store? I don't even have a Z110 yet, and will probably just use the mute wire once I get it, just spitballin here I guess.
