There are features I like about this, and in my basic test tonight, I have not been able to test some of the 'fancy' features it has. Here are some initial thoughts: The Good Much more pleasant voice I loved the fact that it put up a speed limit sign in upper right, showing the speed limit of the street I am on. Updated immediately when SL changed As others have said, it seems to definitely handle the funky Captivate GPS better Seemed to get directions faster, and update faster when not following directions, than Google Nav It does have a Google Search for POIs, although I found it did not bring up a complete list. For example I searched for Walmart. There are 2 in my town, and it brought up only the one closest to me, which is a much smaller one than the other The Ugly It did not consistently say street names. In fact most of the time it didn't If you moved to another app, or if my music player came in front, the NAV stopped working. When I switched back to it, it had to re-load or something (had a wait type message) and then had to reroute When playing through my Motorola 505 through to radio, the voice played on both the phone and BT, and this phone (maybe all Android phones, I don't know) has a delay at the bluetooth (often do not hear the first 1 to 3 words), so it sounded like an echo The map had almost none of the streets named as you drove. It just listed the next turn street listed. It didn't even indicate what street you are driving on. My comparison software would be Google Nav, of course, and also TomTom on Winmo, which I used over the past 3 years. There are features in Navigon that are not in either of those, but for the basics, it doesn't, IMO, come close to Google, nor my OLD TomTom. My need for this would really be only to have a backup solution should I go somewhere that I cannot receive data for Google. I am undecided whether to keep it or return and hope TomTom is better, whenever it comes out. I must admit though, one thing that this product, I belive like others, may not put me on wrong streets like happens with the Google Nav. But then, I haven't tested it that much yet. Very short time with it, and overall review may be biased away from it, but this is first impressions.
