Provide a speedometer and compass widget which can be used in Car Dock Home v3, or any other widget supporting app, while in car mode.Uses the gps for speed and bearing. It does not use compass sensor in device, so you will have to be moving to see any change in direction. Tap the widget to bring up prefs screen… Options are: MPH or KM/H display Font for speedometer reading Color of speedo and compass Background color of the widget Transparency control of that background.You might not see speed unit change until the next update from the GPS. If the gps is not sending updates, "NO GPS" will be displayed. Updates are requested from your phone at maximum update frequency. When not in car mode, it will also show "NO GPS" as it does not receive gps updates outside of car mode.
