I have tried to follow your instructions for obtaining an unlock code to obtain traffic capability. I have a Nuvi 760 and a GTM 20 traffic receiver. When I go to ADD in the traffic menu I do NOT get a traffic receiver ID. All I get is my unit number. Am I supposed to get an ID number from the GTM 20 itself? Even if I were to obtain a traffic receiver ID number, where do I input it in the Jetmouse Keygen? There is only a Unit ID entry. Is that supposed to be used to input the ID's for both the Nuvi and the GTM 20? I am confused.
