Each TMC receiver has its own 10-digit ID.
This one is another number then nuvi ID, you can find it only when nuvi is connected to TMC receivers. Go to menu Tools, Settings, Traffic, Subscriptions, Add and see message containg your TMC receiver ID.
See Post number 1 for providers

Slovenia, Radio SI/TrafficNav (SI): 18689, 33, 33, 1

I know this.
But i dont know where to find number 18689, 33, 33, 1?
Where can i find number 18689?
Someone must find this number somewhere and i like to know where he find this
18689 = 4901 hex
compare to TraficProviders.xml, description for Slovenia: cc="9" sid="1" ltn="33"
And look for the same values in nuvi developer menu, TMC tables.
V-Trafic (FR):
FID=cc*256+sid=15*256+62=3902 REMARK: It's not always factor 256 for all FID calculations
PID=ltn1=30
RgnID=ltn2=32
VenID, use 1 for insert and 0 for remove
Via-Michelin (FR):
FID=cc*256+sid=15*256+58=3898 REMARK: It's not always factor 256 for all FID calculations
PID=ltn1=29
RgnID=ltn2=32
VenID, use 1 for insert and 0 for remove
Looking here in post #1 you can see the 2 code sets for France
It was a year or two since I've tried this calculations. I don't have the complete calculations for all providers but this can be used as a starter for further investigations. The hardest to calculate would be the FID if you don't have a real 25-character unlock key to investigate with [Only registered and activated users can see links. ].
EDIT: Here's some more examples of my own previous investigations.

Maybe someone could find the pattern for generic calculation of FID values for TMC?
I don't know the formula for FID in TMC calculations. Just some fragments with PID, RgnID & VenID and where FID is adopted to fit the wanted result. I'm using binary factors (2^?) as fillers so the pattern would be easier to see in possible operations with XOR, OR, AND, BIT-SHIFTs etc.
My time is limited to investigate all possible ideas that floats around. I tried to explain the initial seed for the TMC calculations and there has been other explanations earlier in forums that crashed and lost their stuff (eg. **** & erased posts in PPC W**ez).

Anyone who is interested and like to do further investigations are welcomed to dig deeper into this problem : anim18):
