Online Maps Location Service is a wrapper for Unity Location Service.

Try using Unity Location Service directly.

To dynamically create a map, create a prefab from the map gameobject, and instantiate it when you need it.

I know in Unity Editor , I can't get the GPS coordinates. I clean the inspector's number of  latitude, longtitude  and check online maps service script in map's inspector .When I built the android apk  in my phone. Map didn't change the location by GPS.

Is possible to change map depending on online Maps Location Service
?

Latitude can be negative (range from 90 to -90).
In Unity Editor, you can not get the GPS coordinates, because you just do not have a GPS sensor.
In Online Maps v2.4 (available through the built-in update system) has a new feature - Find Location By IP, so in Unity Editor, you can find your location up to the city.

is possible when I playing the map ,showing the location by GPS.
