Sadly no way at all to remove the nav system. It is integrated into everything.

Hey, I need to know your opinion on something. I would not necessarily consider myself an audiophile, but I enjoy listening to crisp clean music. I don't have a Z yet, but I am looking into get one. I am on a budget however. Living in Colorado all Z's seem to come at a premium. I currently have a sound system. I mean Headunit, speakers, subs, amps, and everything to install it, but the best deal I can find is on a touring Z with Nav. I know its asked a lot, but is there any way to put an entire non touring set up in the dash? if so would it entail completely new harnesses. I'm just trying to figure out if it would be worth the effort, or if I would be better off just buying a non nav z. I know it is possible to replace. It just seems like a lot of work to adjust signals and everything and rewire everything to get it to. Any feedback would be appreciated.
