Here is my mini GPS roundup review:
I installed the Navigon app yesterday and say I was highly impressed. I have tried Gokivo, AT&T Navigator, G-Map, and now Navigon and I have to say out of all of them, the Navigon is the only one that I would use. First it actually had the most accurate route, second it was the only one that didn't give weird turn offs and gave appropriate time to turn. On AT&T Navigator it told you to turn two blocks early without saying the name which would make you turn off on the wrong road, G-Map tells you to turn right when you are at the turn with no time to turn. That was annoying. I was also surprised that the Navigon had the speed limits down to the wire, as I passed by a Speed Limit sign the GPS updated to show the speed limit even in small towns. Wow. I only wish it had full spoken street names (it will say highways and interstates). All in all, the others had their good points, the Gokivo has full turn by turn with spoken street names and a great trip summary, the G-Map has the current street shown along with the next street at the top which I liked. The AT&T really didn't have anything I liked except maybe the lowest priced gas feature.
