Speed HUD uses your GPS and phones screen to display your speed
You can reverse the text so you can put your phone on your dashboard at night and see your speed on your windshield, keeping your eyes on the road and not looking down at your speedometer
You can also:
* Log and export KML files to Google Earth
* Speech support - get speed and camera warnings (with appropriate database file)
See the 'Torque Pro' app for more dials/widgets and customisable dashboard layouts, HUD options, colours and themes!
