Thread: Using TMC in Garmin nuvi for free

for your expired TTN you can try with this:

USA, Total Traffic Network (US, CAN): 28992, 0, 0, 1

Canada, Total Traffic Network (US, CAN): 31808, 0, 0, 1

If you have 3 months subscription code you paid for it we can find out your pid,vid... and then you can unlock to lifetime.

Thank you for the responses. I am a bit confused. I do not have the original code as it was preloaded when I bought the unit.As for NAVTEQ, I did not see it installed on there to reactivate it. Does this mean that If I use the NAVTEQ codes,I will have it? Also,lolypop000,These are the numbers I have used over and over and still shows expired.I have created a code 3 times for both US & Can and installed both 3 times. I hope I am not getting near the "limit" as to have it locked out. I have tried putting each code in and restart in pre-boot for each Then I tried putting both codes in (diff codes generated) then rebooting to pre-boot mode.Still expired.(does say lifetime for 20 sec or so) Is there another way to find the expired code to see what the other info is? Thank you very much.....spoc

If you want to take screenshots on a Nuvi 6x0, touch Settings (wrench)>Display and turn Screenshot On. A quick press of the power button will save the ss. Beats using a camera .

Ok thank you much

Situation is quite odd:
Added the previous code, it showed Subscription added, also with the name Netstar Alltech...
Then its searching the providers and suddenly the subscription is gone, like I never typed it inside.
Not sure whether its related to the Firmware, or having CN South Africa and Garmap 2011 3rd Edition installed, or that both maps are unlocked.
Thanks for the code, I will try and update here

lolypop000

goes to lifetime and after about 20 seconds goes to expired. added both US & CAN

This is a GTM20 receiver. Does this make a difference?

You can try with this:

Generate code with this:

USA, Total Traffic Network (US, CAN): 28992, 0, 0, 0

Canada, Total Traffic Network (US, CAN): 31808, 0, 0, 0

(number 0 on the end will disable supscription)then turn on your nuvi.

After that add unlock code that i send you to PM.
