Thread: Using TMC in Garmin nuvi for free

I have a 3790
Tried this:
>>U need 3 Unlock codes:
>>FID 1527 to generate a subscription valid November 6, 2023
>>FID 28992 for a TTN subscription for USA
>>FID 31808 for a TTN subsscription for Canada
Anything I enter, it gives me a message that I need to update the FM traffic provider database, and suggests to use web uploader.
Any advice?
Thank you

I everybody, I'm new to the forum, went through all of the 251 posts on this thread, only thing I managed is to add subscription for the Navteq free system, the TTN always expires. i followed procedures on post 10 & 42, I add both codes for US & Canada, but it always expires after a few minutes. If I try, as user erweb, to put the code with FID 1527 with the 4 digit generator, I get his same msg, to update Traffic FM DB. I have a Nuvi 1390 with SW ver 5.30, gpS 4.30, GTM 5.50. Any clue?

Actually, I wasn't even able to enter the TTN code for FID 28992 - got the same message about Traffic FM DB. I did manage to enter Navteq codes, but I don't think I got rid of ads.
