Log into Facebook with the profile that you are wanting to detach from NUVI.
Once logged into Facebook, navigate to the top right drop down arrow and select Settings.
In settings, you will select the Apps button on the left hand side of the screen.
You will then see a list of applications that have access to your Facebook - you may have to select Show All from the list but locate the application that states ‘Social Media Application’ and select the ‘X’ once hovered and it will Remove the application from having access to your Facebook.
Once removed from Facebook, you will then navigate back to NUVI and the Social Profiles page. You can then select the trashcan icon next to the Facebook social profile in NUVI to completely remove it.
WARNING: This will remove any scheduled posts for this social profile.
