All thanks for the help. CC support is great. Heard back from them and the fix was very easy. The Satellite Dish Hookup plate is only if mounted on the roof. If you have a mobile dish then you use the Aux/Sat port which goes to the bay connection.
I thought that this attachment would help others if they have the same issue.
