Navigation option

[ohioZ]

Hey all,
I'll be buying a Z in the near future and I've been debating the options. My question is about the navigation package. Do those of you who have bought it feel it was worth it, or wish you wouldn't have bought it? And those that didn't buy it, do you regret not buying it?

My main problem is I hate the look of the center dash without it, but its only available on the touring model (more and more $). I feels like something I'd be kicking myself every time I drove it if I didn't get it, even though my bank account would be hurtin.

Thanks for the input!
