The company I work is called Metaphorix for specialise in Microsoft Dynamics NAV and also sell Microsoft Dynamics CRM and have experience in intergrating the two systems.
Customers are often surprised when I explain the two systems are actually two separate systems, especially when they both have the words Microsoft and Dynamics in the name of both products.
I have noticed that over the last 6 months there has been an increase in NAV customers wanting to use Dynamics CRM 2011. There is some CRM functionality that exists with Dynamics CRM so it’s important for customers to have all the information when deciding if they want to use the Dynamics NAV CRM functionality or go for Dynamics CRM 2011.
If you are wondering what the differences are between Dynamics NAV CRM functionality and Microsoft Dynamics CRM 2011 functionality then I recommend you read the flyer created to help explain the functionality and differences.

I think the increased interest from NAV users indicates companies are realising the importance of CRM but also want to use CRM from within Outlook, CRM 2011’s Outlook add in often allows users to work the same way as they did but also benefit from the advantages CRM 2011 gives them.
The users who are often responsible for CRM and marketing often are not NAV users which I think might explain their preference for using Dynamics CRM 2011.
I would also say CRM 2011 is easier to use and gives users the ability to easily modify the forms and fields used and has better marketing functionality than NAV CRM.
CRM 2011 is not always the best choice, it depends on what you want to use CRM for, how many users will be using CRM and some other factors.
