Thanks, Boki_Srb,

I have some little news, but TMC is not working yet!

As I told, I was able (with tmc_fix utility and adding tmc_station list in save folder) to have the Traffic Summary on Scanning 102,5MHz. And I had this only by adding in sys some voice about [tmc-http]. Today, I've seen another interesting fact: the tuner changed from 102,5MHz to 87,6MHz and 87,7MHz, but always without indicating traffic events. And I think is not important, because the scanning happens also without antenna!

It's like the TMC antenna is recognized, but I'm not able to receive tmc events! And TMC_Scan again doesn't work, giving the following errors:
- Unable to connect to port 1 (when iGO is running)
- No reply from module (when directly I run TMC_Scan)

I've seen in the original device, in the file My Flash Disk\Program Files\Navman\SmartST_CE\Userdata\device_settings.ini something that I think could be interesting:

Spoiler: device_settings.ini

[default]
gps port open=true
gps port=COM8
gps baud rate=57600
gps default protocol is nmea=true
gps sirfbinary protocol=false
gps sirfbinary baud rate=57600
gps protocol switch=false
...
...
tmc port open=true
tmc port=COM1
tmc baud rate=14400
tmc duplex mode=true
tmc gns module=false
tmc command timeout=100
tmc command retry=3
...
one2one port open=false
one2one port=1
one2one baud rate=115200
...
fm transmitter available=false
...


Now, about the line "tmc gns module=false", has something related with the messages?
And in sys I've the voice internal_tmc_name="gnsport" and I wonder if I must change in "gns".

By the way I think that:
- we can see that the TMC antenna is recognized
- licenses are all available
- I need in sys the [tmc-http] settings (but why is it important and which are the correct parameters?)
- I receive frequencies scanning but...
- I don't receive tmc messages.

It seems like the problem is in the messages not received, and not in the setting for the scanning.

Concluding:
TMC_Scan doesn't found and FM station, so I can't receive messages.
Is it a matter of settings or what other?
Is this model of Spirit that need some other setting? Don't forget that also for the SD Card to be recognized, this model needs a script!

I think there is the only one question:
How can the spirit 6970LM Truck receive RDS signal, that we can verify by TMC_Scan?

This is the big problem!
