Recourses for the Magellan Crossover

I've been stumbling blind for a couple of days in a renewed effort to find crossover resources. I tried when I first got it, but that was when it was first released and most retailers didn't have it yet and the Magellan website barely even mentioned it. I was hoping that by now there would be a wealth of custom POI library, base maps (as Magellan promised but hasn't yet delivered), hacks, and the such. Unfortunately every time i think I'm on to something it doesn't support the crossover. Magellan seems to have forgotten they ever made the thing, and it seems to be little more than a byword on the forums I've seen.

So now that I've rambled enough, I was hoping this post could serve as a dumping ground for everything crossover compatible people have come up with.
