Thread: Using TMC in Garmin nuvi for free

Hi all,

Have an 885T with the Microsoft Direct Service cable and service whose service was stopped 1-1-2012. Bought a used GTM20 cable preparing for the stoppage. It arrived to day. Using v1.5fixed generator, generated BOTH US and Canada codes for Navteq traffic and entered in to 885T - US activated immediately with Lifetime for US and a message showed up stating subscription would be activated once I was located in area (Canada). Next, entered BOTH US and Canada codes for TTN and the Expired message appeared. Used Keygen v1.3TMCexp generator using 1527 in the Custom Map block and entered generated code into 885T and TTN Expired turned into Lifetime... Thank you all very much! Will miss the MSDirect information greatly but at least I now have Traffic... One note, TTN channels show, but others are not named, so I am assuming they are the Navteq channels but do not know that for certain. Turning back to the Map, after a few minutes, traffic does show on the map, but do not know which service is providing it. I am not able to select as far as I can tell, even from with the Test/traffic Info or the other key. Good luck to all and Happy New Year.

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
