Thread: Using TMC in Garmin nuvi for free

Any chance that you upload the 4.1 FW version?
Should be a GCD file in the Garmin directory.
When did you buy the 765?
The FW 5.5 should not have any limitations in adding TMC.
I remember there was a posting long time ago regarding erasing all subscriptions, but this involved a data programmer.
I removed subscriptions, but they were not showing up anymore in the diagnostic menu, whether they complete erased is not known to me

Unfortunately there is not a GCD file on the unit. I only just got the unit and so it came with this firmware already on it.

When I go into the diag menu by entering via holding the speedometer icon, the unit lists various subscriptions (although some are called "Not Named", the ones I tried to remove using VendID 0 do not have names there so these could be some of those, presumably along with ones that successfully added but never showed up in the subscription list in the Traffic menu).

Looks like I have to buy a new TMC then as there seems to be no way to remove these subscriptions...

Does any member have a friend who use the Thai 3770 with TMC cable? If yes, could you please help to check the Unit ID of the GTM 35 Thailand Cable?

Every UnitId is different of the TMC cable, so what do you try to achieve?

Sorry, u confuse me. U made a Subscription for USA, but which subscription do you wanna have?
The TMC UnitID is shown when you connect ur antenna and wanna add a subscription

I want to make the subscription for Thai TMC with Thai Map FID 2338. I use this ID with the Tools and it show the subscription for US. I was thinking that if we have the Thai GTM Unit ID to gen the Code and use this code with "InfoUC_v1.05.exe" which is a reverse key parser. The Family ID might be a different set and it might be use only for Thai GTM 35.

Sorry if this is a worry thinking. So far there is still no solution to unlock Thai TMC here.

Yeap, that was wrong thinking.
FID 2338 is for unlocking the Thailand Map, by coincidence it also can be used for Lifetime subscription of USA/CAN (with some additional parameters and old Keygen).
Normallly TMC subscription requires a different FID (for example Germany: 7474,1,1,1).
But Thailand has from my knowledge no subscription what you have to pay for.
If it's really Pay-Subscription (what I doubt), then u are currently out of luck. No FID known so far.
If Thailand has TMC, then u should receive it for free if your are in the coverage range.
More important is, that you have the current "TrafficTrafficProvider.xml" in your device (v2.70) then u should receive it.

<provider>
<providerName>Thailand GT</providerName>
<pay>false</pay>
<tuning ltn="10" sid="30" />
</provider>

Thanks for your information. I already have the "TrafficTrafficProvider.xml" (v2.70) in my new FW update. When I use FID 2338 with KG 1.5. The device accepted the Gen Code but it doesn't show the subscription as above.

Maybe we don't have any luck to unlock it because so far NO FID found. In Thailand, the service is still free and the local device could use it with GTM 35 Thailand. So Far we still don't know where is the locking point. Maybe it is the Firmware.

Thought my previous posting was clear.
Where do you wanna have a subscription for Thailand when it doesn't exist?
So if a subscription doesn't exist what do you want to unlock?
Once again, the FID 2338 is only for unlocking the Thailand Map v11, nothing else.
You can type 20 times the generated unlock code in ur Traffic subscription page, it won't show up at all
