Select Locations on map

Hello,

I would like to integrate a google map, where you can select your location/town, select a circuit and a division to find the nearest distributor.

Similar to this:

To maintain the backend you should just have to insert some locations and it will find coordinates on the map itself.

Is there already a tool/plugin/code which can do this?

Thanks

Edit: Of course it should also show some more Information like phone etc. by clicking on the map.
