开车用的导航显示软件，可以将所有的行车资讯，包括目前速度、平均速度、方向、海拔、天气预报等预测资料利用屏幕反射限时在挡风玻璃上，还能提醒超速。

晚上开高速路时把屏幕反射到玻璃上很好用，可能有的朋友说功能太花哨了，不过目前限时免费中，下来玩玩还是不错的。

- direct distance (kilometers, miles, nautical miles supported) to the starting point of your trip.
- maximum reached speed, altitude and distance to start point, for the current trip and all the trips your ever did.

Comparing with others HUD displays on the market - better look and more features for no price.

Tapping the "HUD" icon mirrors all the text, so if you position the iPhone horizontally under your car's windscreen you can see perfectly readable half-transparent reflection of the picture displayed. We love this mode! We found it much more convenient compared to traditional car dashboards (especially on the roads of Western Europe, which are full of speed cameras and where you need to watch your speedometer all the time). And last but not the least - it just looks cool. *Note: this mode works pretty well at night time and twilight, but on direct sunlight the screen brightness can be insufficient.

- "aSmart HUD" can keep track on 4 speed limits, giving a warning (sound and visual) each time you crossing it. Normally, it's legal speed limits within cities, local roads and high-speed motorways. "Never exceed speed" is the speed you should not exceed under any conditions. For example, it can be a technical limit of your vehicle or the point where government can arrest your driving license.
- You can skip/rewind/play/pause your current iPod music track, select the playlist or set the Shuffle or Repeat iPod mode.
- Weather forecast time intervals and temperature units (C, F) are selectable in Preferences.
- You can quickly take a photo of what's going on the road. Photo will be automatically saved into the Photos Album. The speedometer image, map and a some of other useful information will be placed over your photo.
- Landscape and Portrait screen layouts support.
- Three different compass styles, sound themes, colors, etc.
NOTE: Preferences - Display - Enable 3GS Magnetometer switches on magnetic compass support (not available on iPhone 3G). When OFF, compass shows the direction you are moving, not how the iPhone is oriented.
- 3 functionally different display themes.
- Speed history log chart.
- "Location Info" - longitude and latitude, GPS measurement precision and some more data.
- "Records" screen (left upper button on the "Location Info" screen), where you can see your maximum reached speed (during the current trip or all of your trips), maximum altitude and maximum distance from start.
- Tap the speed indicator to switch into speed fullscreen mode.
- In Preferences, you can specify different measurement units (miles per hour, kilometers per hour, knots and meters per second), display color scheme, speed log chart refresh rate and chart style (bars or dots).

Limitations
- The precision is affected by the satellite signal quality. If unsure, use the program only for reference, don't rely on it for 100%. Application requires real A-GPS chip - so, no iPod and not-3G iPad supported. On iPad 3G application function only in "double pixel" mode.
