Yeah, the iPAQ Navigation software is the same as well. In fact it recognised the maps from the iGuidance disc and I had to uninstall it first then reinstall the iGuidance for it to update.
Routis was also the same package.
Current version shown on inavcorp is 2.0, but I just got 2.1 shipped to me as an upgrade. It's three CD's of maps and it works extremely well. 2.0 was two CD's. If you buy it, you can upgrade for just the shipping costs.
The routes are quite good and the current maps are better than the older version 1.0. Also has the birds eye view.
What really impresses me, is there's a spot where I drive on to a highway and depending on where I need to go, it tells me, bear right, bear left, keep left, or whatever, to ensure I'm on track.
Very accurate.
The latest version also has a gong of sorts that alerts you, so you're brain is at attention for the voice command. Works well. I've missed commands before, when not paying attention.
There's also a speed alert you can enable, which is very accurate. Could save you a ticket when the speed changes.
Overall, I'm extremely pleased. What's really cool is playing music off my iPAQ through the Pac Audio adapter and then the voice command comes through. It doesn't have Ipod capacity, but with a 1 Gig SD card, it's not bad.
I put the XM back in, so I have to work out a different interface for that now. (and I will...)
