Thread: Using TMC in Garmin nuvi for free

Thank you for your immediate response. You are absolutely right. I got the ID number and used it to generate the traffic codes. I was able to obtain the Navteq code and it works perfectly. Sadly, like everyone on this forum, I have been unable to obtain a code that will last for more than a few seconds for the TMC. There are no specific instructions as to how to obtain a permanent subscription. I have pretty much tried everything except using the modified Jetmouse 1.3 key generator which I can't seem to find anywhere. Perhaps that is the key, I don't know.

If anyone has the correct instructions to getting it to work properly please let me know. After going through over 400 posts it seems like the original instructions in post No. 1 do not work for the TMC subscription as they have been put up.

Let me ask you this....

Before you tried to enable TMC on your GTM dit it already have an EXPIRED subscription ?

To get lifetime Clear Channel Total Traffic for US and Canada "TTN"
************ Tested to "EXTEND" an Expired subscription
IMPORTANT: you MUST use the modified keygen "jmgkg13modTMCExp.exe"
use custom mapset with a family ID of 4094 (some say 4095 also works, I've never tried 4095)
NOTE: If you run the generated key through the Key Parser it should reveal a valid key with
a mapID of 28992 and an expiration date of about 50 years from now.
