The gmt25 as can be seen here [Only registered and activated users can see links. ] has lifetime traffic support. Probably the gmt25 that was coming with my device has inside the european codes. The gmt25 has many versions ([Only registered and activated users can see links. ]) so depending which one you have, it might or might not work in the area you're in. I bought my 1490t in greece so it probably is a good version.
I think they recommend the gmt35 because they know that it is working for sure with their tmc. Either way it is better to try every receiver to see if it is working.
