I haven't looked too in depth, but I would imagine that any of the double-DIN sized units would work. Something like the Pioneer AVIC-Z2 and AVIC-C3. The roll out screen models don't work as well because the radio cage sits too far into the dash, and the screen can't rotate fully upright without hitting the panel above, plus it would block the climate controls.
Here's the link to Pioneer's nav units:

Some nav units have the screen which fits into the dash, and a second "box" which is the actual navigation processor that has to be installed somewhere else. Pioneer (as far as I know) has everything built into the dash unit. There's the reciever antenna, which has to be mounted somewhere too.
SVXdc makes/sells wire harness adapters, which should make everything work just fine.
