I have been a user of colpilot live, Tom Tom, GoogleMap, MapKing, and iGO My Way.

The best in my opinion is iGO for the following reasons:

1) It is the only one that warns you if you exceed the legal speed limit. This is in addition to red light and fixed camera warning. Tom Tom only changes color if legal speed limit but has no audio warning. Mapking assumes a estimated road speed limit but does not keep the real speed limt in its database so the warning is not useful. All other software do not even have such warning.

2) Beauty of its user interface

3) Speed and responsiveness

4) Tolerance for gps inaccuracy due to weak or even lack of signal strength inside tunnels.

5) Availability of maps

6) Abikity to obtain 3D lock within 10 seconds, if the gps seting is correctly done.

7) quality of sound and spoken voice.
