OMK consumes internet data when using online OpenStreetMap instead of imagery as a basemap background, unlike GPS units that do not have a need for internet as they use satellites to geolocate.
OMK inatumia kifurushi cha mtandao wakati wa kutumia OpenStreetMap kwa mtandao, badala ya picha kama picha ya nyuma, tofauti na vifaa vya GPS haiitaji kifurushi cha mtandao, ambapo inatumia sattelite kuonyesha maeneo.
