Keep Position On Road (Lock-On-Road); About Screen - Mio DigiWalker C310 Software Manual

The Overview zoom level will determine the fixed zoom level of the map in both
automatic and manually selected (by the Map orientation icon – see here: Page 28)
Overview modes. You can change the zoom level manually at any time (the Lock
button will not be displayed), but when you enter the Overview mode again, the
zoom level will be reset to this value.
You can also move the map in Overview mode. Then the Lock button will appear,
and when pushed, it will move the map to have your current position in the middle
again.
Note: when this automatic feature is disabled, you can still enable the Overview
mode manually as described here: Page 28.

6.5.5.3 Keep position on road (Lock-on-Road)

MioMap is normally used for vehicle navigation, therefore Lock-on-Road will display
the position arrow precisely over roads, seamlessly correcting small GPS errors. For
pedestrian use you may consider disabling Lock-on-Road to make MioMap always
show your exact position.
Note: By turning off Lock-on-Road you also turn off the GPS position error filtering.
The position shown on the map will be subject to all position errors and position
fluctuations.
