how to change map locations based on radio button clicked

I am trying to show map in site. unfortunately its working good. Now my concept is divide into three parts of page. half for map and 25% for check boxs (generated by DB. name of the check boxs from db).balance 25% for images(based on check box image changed( this image from db). everything working good. like when i click check box image updated nice. but the map not update. (i want this, when i click check box get latitude and a longitude from my db and update the map), now my map not showing. image only update.
