I generated the unlock codes for Bulgaria, Ireland, and Greek at home as well as the pan european codes several weeks before all working correctly. After several attemps (unlock code incorrect length, maybe my mistake) all three codes (Bulgaria, Ireland, and Greek) were shown in my nuvi 1255 as well as all the others with lifetime abo. But when I disconnected the GTM 25 and connected everything at home and in my car only these three stayed completey disappeared til today. Why? Any help is appreciated.

Because signatures are initially in volatile memory and then are recorded in non-volatile. You have reached the maximum number of signatures, supported by non-volatile memory of gtm25, so they disappear on startup (or finalization) when would be recorded .

I have a GTM25 with the same problem.Last edited by angelozip; 7th April 2014 at 02:18 PM.

The 1350T I bought early 2013 for my dad and made all the firmware updates even 3:10 firmware of gtm25 traffic receiver, then I installed acleite sd unlock procedure to unlock JCV and Lane Assistant. All went well at the time and as my Jetmouse traffic signature did not disapear I did not follow your procedure to downgrade the firmware back to 3:00 firmware.
Recently I purchased a 1310T second hand again this time for my wife because she prefer using it to the IGO PRIMO I have on my car… I did everything as above except updating GTM firmware to the latest Update. I did not update the GTM because after doing this on my 1350T the year before I read that could block the signatures. ( which had not happened yet).
After I updated everything on the 1310T, except the GTM firmware everything seems to working but do not know which I GTM firmware update I’m using ... how to check this?
Also, my father travelled abroad so I took his 1350T to play and see if the traffic info had improved lately, for I live in Embu and work in Sao Paulo, I like to see what is the best highway in Sao Paulo, Raposo or Regis…
After some days using it without any problem the traffic icon took some time to show on the screen so I entered the Traffic option on the configuration to if the last update I did in traffic provider had interfered in the signature. And I had a surprise , the following message appeared :
The traffic signature has not been activated . Activation occurs automatically when your unit gets satellite signal and receives data on traffic .
I press OK and appears :
Habiitar traffic , selected
HERE Traffic ( US , CAN )
Subscription Period
HERE Traffic ( BR )
Subscription Period subscription
And funny thing is that the icon came back that the traffic map still works .... I didn`t know that NAVTEQ has been renamed HERE!
What do you think I should do? Make your procedure to downgrade the firmware or simply ignore everything?
Again regarding the 1310T how can I find out which firmware I’m using, the last owner didn`t update since he purchased it back in 2011!
