The Bolt2 uses the VTM rendering by default.
On the Other devices you can enable it by creating a file on the device with the name "cfg_BHomeActivity_VtmMaps" it will use the new rendering method. Another file with the name "cfg_MapPanZoom" enables panning and zooming on the map.
Create a new file in "maps/vtm-elemnt" with the name "vtm-elemnt.xml". You can copy the latest theme from https://gist.github.com/Intyre/7494d5c6c86b5bc60ce4d03b9cfce2df
