I tried but I think it's useless mainly because the gtm cable is not detected: in settings, traffic i see "TRAFFIC: enables traffic - traffic receiver cable required". But the cable is plugged in.
Connecting the usb the garmin detects the power source (coming from the 12V car adapter) but not the gmt. plugging or unplugging the gmt cable doesn't change anything.
I tried to restore the original 140.bin, no improvements.
In the hidden menu I've seen the FML number, I hope this is good news.

Create backup of your Remotesw folder and trafficprovider.xml from your .System folder and extract rar in .System folder and try if GTM will work
Try downgrade FW to 6.60 maybe then will GTM work like before.
Create backup of region 139 and 140 and we will compare to 139 and 140 from working nuvi 2495.
p.s.
Anybody have nuvi 2495 with working GTM reciver and can share region 139 and 140?

these are my 139.bin and 140.bin files.
I tried to replace the files and folder with your file but no luck.
Downgraded to 6.60 still no results.
thanks for your help and support.

This is original region 139 and 140 or do you create backup now when GTM wont work anymore?
p.s.
Do we have on forum some user with working GTM reciver who have nuvi 2495 and can create backup of region 139 and 140?

I don't have the original 140.bin because the loader didn't make the backup before writing the patched version.
I saved the original supported_features.html so starting from that I recreated the 140 like it was before. [Only registered and activated users can see links. Click Here To Register...]
I made the backup of the 139 today, but I never patched it, so I think it's still the original.

OK,we must now wait for someone with working GTM reciver to share region 139 and 140 from nuvi 2495 and then we can compare ;)

double check if the trafficprovider.xml is there, as well as checking with the webupdater perhaps the GTM firmware is missing?

@bpb:
I've checked, and trafficprovider.xml was there, and gtm firmware was up to date.
@lolypop000:
Then, after deleting the region 41 file, the gtm started working again but:
after the reboot, the nuvi said it couldn't unlock the maps, so I tried to upgrade them with map updater (from 2013.10 to 2013.20) and maps now are working.
The problem that I still have is that every time I start up the nuvi, he keeps asking the country and the agreement for the contracts.
I've changed the MTP and screensaver settings, and the nuvi remembers them, so it's not like at every reboot the device just resets forgetting everything saved.
Do you want me to post the 2 reg41 files to take a look at the differences?
fw now is 7.20
thanks again to everyone for the help
