I know the website states that this won't work with navi, but isn't there a way to hack it?!!! Aargh! Although XM is an excellent replacement for the iPod right now, I still want to use my iPod withouth resorting to the cassette adapter, FM mod, or taking over the XM channel. I've seen the definitive iPod thread here but it'd be great if they could get this thing to work with those of us with Navi.
