   `mapStyleV2` is not supported for current version of echarts bmap extension. But you can modify the source code below the folder `/extension/bmap/` for your custom requirements. 
   Demo:
   `/extension/bmap/BMapModel.js`
   ```
   ...
   defaultOption: {
       center: [104.114129, 37.550339],
       zoom: 5,
       mapStyle: {},
       roam: false,
       enableV2: false // ADDED
   }
   ...
   ```
   `/extension/bmap/BMapView.js`
   ```
   ...
   var newMapStyle = bMapModel.get('mapStyle') || {}; // FIXME, Not use JSON methods
   var enableV2 = bMapModel.get('enableV2') || false; // Enable setMapStyleV2 or not
   
   var mapStyleStr = JSON.stringify(newMapStyle);
   
   if (JSON.stringify(originalStyle) !== mapStyleStr) {
       // FIXME May have blank tile when dragging if setMapStyle
       if (Object.keys(newMapStyle).length) {
           enableV2 ? bmap.setMapStyleV2(newMapStyle) : bmap.setMapStyle(newMapStyle); // MODIFIED
       }
       ...
   }
   ...
   ```
   Then configure the option:
   ```
   option = {
       bmap: {
           center: [120.13066322374, 30.240018034923],
           zoom: 14,
           roam: true,
           mapStyle: {},
           enableV2: true // CUSTOM
       },
       series: [{
           type: 'scatter',
           coordinateSystem: 'bmap',
           data: [ [120, 30, 1] ]
       }]
   }
   ```
