The newest version of Vasco (5) (Still very pricey) has some very unique features in it........you lay out your complete itinerary by labeling the cities you are going to visit and then a built in World Wide GPS system automatically creates your route.
It has a built in World Map; but you can add your own maps as well........It even has monuments and historical buildings that you can add along your itinerary
There is a camera built into the software so you can get a 3 dimensional "effect" and you can track your moving
device from various angles............
The user interface is not very friendly but they SELL a video tutorial for about $100 US.......UG!!
Most of the you tube tutorials are in languages other than English........Ug UG
Another key difference is you can insert video clips along your route which adds a lot of realism.....
Here's a VERY EARLY PREVIEW.........about 90 seconds (NO SOUND COMES WITH VASCO)
