Thread: Using TMC in Garmin nuvi for free

Thank you very much....Will give er' a shot

It worked great for about 30 seconds or so. It went to Lifetime subscription to expired again. I have seen this alot in this thread,but can't remember the fix (if any) Do you have any suggestions about this? Thank you very much again for all your help....spoc

Well, I read through all 392 posts again.Did make some changes. I created a code for US and installed,rebooted then installed code for Canada and rebooted. It still comes up with sub expired. At this point I am at my wits end LOL If I am not close enough to the radio signal,will this happen? I would really like to get this to work, but can't figure out what is wrong. Any ideas greatly appreciated. Thank you very much....spoc

Edit #1: lolypop000.........Anyone????

Edit #2: Ok, I realize reply's are almost non-existant because there are so many posts about this thread. Everyone thinks someone that asks questions with all these posts is just lazy. This is not the case! I have read this damn thread in full 3 different times along with hours on Google trying to acomplish this. Here is what I learned on this thread form this site. Use the newer keygen to create unlock code. Instructions for this say to put in Unit ID and radio ID which is impossible.Then you have to add BOTH US and Canada to keep from expiring. DOESN't work for me. Then you have a guy that makes a code from a "random" number in the older keygen. That doesn't work either.Then someone says,if you do it too many times, your screwed because once its filled,you cant erase all the old tries.On that note,I am trying to get this to work properly before that happens,But after all the typing I have done,only 1 person has taken the time out of their busy schedule to at least try to help. I thought a website like this was for helping people,not ignoring them. Maybe you all know a hell of a lot more about this subject than I, but can guarantee I know more about alot of other topics than most here. If someone were to ask me about something I knew about,I am ALWAYS more than happy to help. So, even though I have done everything posted, Do you have to be in an area that is transmitting for the expired to go away or is it still expired? If you do not wish to help , that is fine,but then why are you a member?

main issue is less experience from the community (may be only me) and very less information form the question raised.

Can you check Developer Menu (Diagnostic page) - Developer info - GTM FM table ? Post the screen, then we see the list of subscriptions.

Do this again once you put in the new code for life time.

Sometime on the reboot unit and also need to disconnect the GTM cable for power source.

nothing !?

Can you check if it's the same screen from this post? if no subscription list I assume no traffic code or it's out of order.

Just for your information:
It seems the code for South Africa, even it's accepted by the device, is not working on my unit.
It shows up in the list of TMC providers, but the traffic symbol never shows up
GTM35 with Nuvi3790.
Probably needs a SA firmware/device

Thank you bpb for all your help. I managed to get a camera and take some photo's for you. I will try to get them on here but been havng a heck of a time getting on this site today. I hope these pictures go through because I only have dial-up. I had 1 more but would only let me upload 5. Please let me know what you think. Thank you very much.....spoc

Can you try the 1953, 17, 17, 1 it will accept the code but acquiring FM traffic is questioning.

sid="128" ?

your unit and this GTM cable worked before? To me it's look like not a correct subscription.

This is the last photo. Also my daughter drove over a hundred miles with it connected today and it never did activate. She also said the unit was sending her all over the place that was out of the way and that never happened before.

Yes, It all came together when I bought it. The green and orange lights work on the plug. The green stays on and the orange flickers.When I had the 3 month sub, it worked great. Now it seems that the person talking sends ya on a wild goose chase. Only thing I did was change map to 2012.10 and mess with this traffic to try to get it working. It originally had 2009 map on it. Thank you soooo much....spoc
