Thread: Using TMC in Garmin nuvi for free

Great Thread. I was able to add NAVTEQ lifetime subscription On my C550 and wanted to test it out when i notice that the TMC cable has some sort of a short in it which I noticed when the traffic subscriptions would disappear and reappear when i moved the cable in certain positions. So i need a New TCM cable and went on ebay looking or a GTM 20. I notice that they sell the one for my garmin with subscription "Part Number: 010-00544-13 " and also without "Part Number: 010-00544-01 ". Is this correct They sell TMC with the subcriptions in them? I thought you had to manually input the key code's? Can anyone confirm this and also would the NAVTEO and TTN be included.

Update Okay i Guess they are available. Anyone know which subscription is better to have. Clear channel or Navteo for North America. thank you
