    Hi Loly,

    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

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

    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.
    Thanks, Kanopus

    Default TMC unlock calculations

    If you have a unit like the nüvi 3790 or similar you can look in "[GPS drive]:\.System\TrafficProvider.xml".

    Here's an example with extract of 2 entries from TMC providers in France:
    Code:
    Please Login or Register to see the links
    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
    Code:

    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.

    Sample calculation with Radio SI/TrafficNav (SI)

    :Anim3: State Type of license Ltn 1 Ltn 2 SID
    Radio SI/TrafficNav (SI) 9 1001 33 33 1
    9=SL 1001 = lifetime
    Formula Value
    FID / MapID State*2^11+2^8+SID =9*2048+256+1 =18689 :Animated77:
    PID =Ltn 1 =33
    RgnID =Ltn 2 same as Ltn 1 =33
    VenID (1=insert) (0=remove) 1

    Sample calculation for Destia Traffic TMC (PL)
    :111anim: State Type of license Ltn 1 Ltn 2 SID
    Destia Traffic TMC (PL) 3 1001 5 5 2
    3=PL 1001 = lifetime
    Formula Value
    FID / MapID State*2^11+2^11+2^9+2^8+SID =3*2048+2048+512+2 =8962 :Animated98:
    PID =Ltn 1 =5
    RgnID =Ltn 2 same as Ltn 1 =5
    VenID (1=insert) (0=remove) 1

    Maybe someone could find the pattern for generic calculation of FID values for TMC?

    I cant figure out formula:State*2^11+2^8+SID

    how do you get from 2^11+2 result 2048?

    how do you get from 2^8 result 256?

    How do you know that is factor 2048 and not something else like 256?

    @lolypop000

    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):

    @lolypop000

    Connect your GPS with the GTM TMC device and look in diagnostic pages for further details.

    Example:
    96815d1330264869 using tmc garmin nuvi free gtm fm status

    I see something interesting from your picture.

    Traffic_nav(SI) 1001 9/e4/1/33
    hex e4 is decimal 228

    <country name="Slovenia" cc="9" ecc="228" fmTuningGrid="World">
    <boundary desc="slovenia">
