Microsoft Dynamics CRM 2013 now comes with an out of the box integration with Bing Maps. This integration uses the address record of your account, contact or system entity to disable that location and render a Bing Map right on the CRM 2013 page.

In order to set this up, you will first need to get a Bing Maps API Key from here:
http://www.microsoft.com/maps/create-a-bing-maps-key.aspx.

You will notice there are several pricing options including a free trial for 90 days. Please decide which one fits your organization best. Now Let’s go Back to CRM to configure it:

Open the Settings, Administration, System Settings. Under the General Tab:

Select Yes, Show Bing Maps on Forms, and then Insert the Bing Maps API Key in the yellow area. Press save. Now when you open your account, contact or custom entity with Bing Map inserted on the form, you will see the map as shown above!

You can insert the Bing map onto a form by clicking the button for Bing maps on the form customization screen under the insert tab. Please ensure you have address information available on the chosen entity for  your Bing integration. Enjoy!
