Honda Navigation.. Think it'll work?

It will not work. From what I have read the whole GPS system is wired throughout the car so just the head unit will not work.

this is true,
usually when a multifunction head unit like that is used, they (the manufacturer) will set up a bus system and put the actual control units for the radio and nav in the trunk or under the back seat. Unless the system used and independent bus for itself, grafting it from one platform to another would present its own challenges. Anything is possible, and im sure it wouldn't be ridiculously difficult for someone with a little understanding and some wiring diagrams.
moreover, i hope it DVD based, or reprogrammable, or you wouldn't be navigating anywhere...
