SmartVolume interprets speed lower than [Slow-Fast] button to be "slow" and faster to be "fast".
When the APP is launched by ON/OFF button, main volume changes automatically to the volume set by [Slow] button when driving slow and to volume set by [Fast] button when driving fast.
The volume is automatically adjustmented within several seconds.
The volume and speed set up is remembered when the APP is turned on the next time.

· Toggle km/h ad MPH: Displays speed in km/h or MPH format.


[Warning]
· The APP evaluates the speed using GPS. The GPS must be turned on.
· In areas where there is bad GPS signal, the APP may not behave as designed.
· When used in parallel with other APP(s) which use GPS, (such as GoogleMaps), the APP may not behave as designed.
· Continued use of GPS running in the background can dramatically decrease battery life.

[Final Request]
· Do not operate a phone while driving; it is very unsafe.
· It is illegal in many countries, including Japan, to operate a phone while driving.
