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.

so far, these parameters do not generate keys compatible with GTMs below 25. Read previous posts please ... You can try using the 4 digit keys Br, mentioned in other posts, together with 5 digits to see the result ...

Nuvi 205 + gtm25 gave me no practical results either using 4 and 5 digit keys here In são Paulo. Subscriptions are added but no signal found. Any idea?

All Nuvis xxx series are not compatible with the required parameters. Probably because these versions of the GPS does not appear to support ecc ..

Well, do you believe we will have any chance with gnose models?

I would say the chances are minimal. Garmin has no interest in the upgrade, and then only if a developer interested is willing to work on the case. The best solution is to upgrade to a newer version ... 1xxx or above ..
