Just read the reviews. Some reviews might be old and sorted ever since, some gives 1* because of missing something that used to have on another navigation, some gives 1* because it wasn't compatible with their phone (or other glitch which wasn't necessary the TT app's fault but other issues).
It is not perfect, but does the trick. Comes with free map updates. The traffic service is a separate in-app purchase though.
