i wonder if you can get refunds if it sucks?
Hope so -- Just got back from a 10 minute drive around the neighborhood with it and it is almost unusable (suburbs, not city, so it's not like there's giant buildings in the way). The software looks and sounds beautiful but the GPS tracking is absolutely horrible. First off, it gets easily confused if you take a turn not on the route, taking anywhere from 3-4 minutes to find where you went. 3 to 4 minutes to relocate you via GPS! This is an inordinate amount of time, especially if you are driving somewhere and you don't know where you are going! Also, the screen refreshing is nowhere near as good as my Garmin unit. A series of quick left and right turns had the Navigon behind by a turn.
If you make a wrong turn it will display you on the path it calculated beforehand for up to a minute and then realize that you have made a wrong turn. THEN it will start trying to relocate you which can take another 3 minutes. This is ridiculous.
If this were a free app that came with the iPhone I wouldn't complain. But as a standalone dedicated GPS app that is going for $70 now and $100 later it is not worth it.
For what it's worth, I'm pretty sure this has to do more with the internal GPS receiver in my iPhone 3GS than anything. I'm sure my dedicated Garmin unit has a much better one, even if it's 4 years old.
I give my Garmin StreetPilot 330 a 9/10 and I give Navigon for my 3GS a 3/10. I wouldn't trust it in any situation where I did not know where I was going, whereas the Garmin I recommend to everyone.
Disappointing to say the least. Now off to contact Navigon for a refund.
