Okay This is the battle of the best GPS's software packages, no hardware just the best and easiest system to use in a CarPC environment.
Let's stay off receiver and crap, I just wanna know who has used Co-Pilot8 and iGuidance and which one you liked better!!
I love iGuidance, but I have to admit sometimes it gets on my nerves, I live in NYC and it won't find simple addresses sometimes.
I've seen screenshots of CP8 and it looks pretty cool, I understand that it's hard to embedd in frontends but I was planning it for dual display anyway, with the GPS solely in the front display.
I don't know much about Destinator, Routis, or MapMonkey, I don't know anyone that has it. For sure, MS S&T and DeLorme are crappy software to use in a car; so I don't even wanna talk about it.

LEt's hear it !!!
