Sharepoint and Bing Maps

Hi,

I'm having some issues with Bing Maps and Sharepoint. I'm trying to create an interactive map that plots locations and details a how much it would cost to transport a vehicle to that location. I need this to be edited by certain members of my team, and I'd like them to be able to pick a point on the map and it adds that to the Sharepoint list database.

Currently i'm having issues with map views as it won't display as a map view unless i create a Web Part Page. But also to get this working I have to manually add the Geo Locations Long and Lat tags for every location which isn't very user friendly. 

Is there anyway to do this or am I am going about it the wrong way ?
