Ah, so that's what "Heading Up" means. Man, looks nice, but what's with the super-slow frame-rate? You'd almost think it was streaming the data off the internet.
This demo doesn't do the app justice when it comes to the frame rates, there actually pretty good and are not as jumpy as the demo might suggest. It's actually pretty smooth.
I just recently took a trip to Florida from North Carolina using this app and I was pleasantly surprised on how well it worked. At first I was disappointed by the fact it did not have voice turn by turn, but I found that it did not hinder the use at all. It has a directional for the next turn indicating miles till turn which is pretty accurate. The only thing I wish it had was the ability to magnify this directional when tapped, for greater visibility. I also read that the next update this month will add an alert in lieu of voice turn by turn.
The only thing needed now is the ability to review the route prior to execution. Without this youre really relying on the apps to route you the best way possible without a quick list view of the route. Yes you can review your route on the map by panning and zooming in at the turn, but a quick list view would be more practical.
