1. If wifi scanning is on, the app cannot get location data, thus making it totally unusable!the graphics help when there are double ir triple layers if roads and highways.
2. much better than Google maps if in a city.This is interesting if I use it in Japan soon, I am very far away from Japan in USA, I'll be using it in Vacation very soon, But IDK if T-Mobile will work unless there's any Japanese Hotels that offers WiFi.
3. Only thing is that you have to know Japanese to use it.Latest android version is requiring wifi scanning option for location service.
4. Tells you toll prices based on the car you're in, gas prices, and has detailed landmarks in turns that are too complicated for other non-native apps to show you.
5. Definitely a necessity for driving through Japan, way more detailed than the other app that's more mainstream.
6. ...or multiple lanes.
