With my nuvi 680 plugged into the traffic receiver I go into the MSN direct icon on the lower right corner and what appears is a 20 character product key for my expired subscription.

I've looked under the all other menus and can't find "add subscription".
Has anyone made this work for a nuvi 600 series?
Is there any other way to get the 10 digit TMC ID?
The only ten digit ID I've been able to find is my unit ID.
