You cant enable future over garmindevice.xml only solution is over region 140 and in this region is only for future and no other data like you say.
Region data is in 139 region.
So when he flash region 140 this is not reason for TMC problem but he change something else or GTM antena have problem.
I try over xml enable future but no luck becouse over xml disable also working future,only working solution is reg 140.

GTM26 and GTM36 have problem with TMC data and Garmin already work on this problem,if someone have problem with TMC,change 26 and 36 GTM for 25 and 35.
