who can adapt gpstmc.dll for tmc?

---

Hello who is ingeniously and can change gptmc.dll for tmc?
Thank you!

What do you mean exactly ?
You want to know if this gpstmc.dll library can be used to retrieve TMC data from RDS using the Polaris's FM radio ?

First, I'd like to know where do this library come from ? What kind of device ? I dunno if raw RDS data is available on the Polaris.

No gpstmc.dll it must be rewritten. Then the TC/Orbit2 TMC.
I can not change the gpstmc.dll, so I look for help here.
Data supplied by Orbit2

The Polaris can TMC.
Signals/TMC are sent to the gpstmc.dll. But will not continue.

Can you explain this in detail ?
I just looked a bit into this:

I don't see where gpstmc.dll get its data, but it looks like a compatible equivalent library is feasible.
I see that FMRadio drives the FM chip thru FMS_api.dll which itself speaks to the FMS.dll FM Chip driver.

What I can see in FMS.dll is that there is a specific event handler for incoming RDS groups but I don't yet know if is hookable. It looks like FMS.dll RDS groups handler filter a lots of feature (probably managing only PI, AF and PS).

Do you have more info on gpstmc.dll inner workings ?

Well. This is not a simple project.

First, a program to test reception of TMC data using the FMS driver must be done.

Then, if it works, a new version of gpstmc.dll must be created (not that easy) to provide software using gpstmc.dll (like, igo or software like that) with TMC data.
gpstmc.dll seems to be specific to devices with GNS GPS+TMC receivers.

Personnaly, I like the idea of getting TMC data from the Polaris radio. If the driver allows us to grab other groups than RDS PS then it can be done. However, providing TMC data to GPS software will be a bit tough.

before you try driver hacks ... do you know what bluetooth chip is inside? after that you must hack the radio rom to switch the right nv-items on. then you can use the drivers.

What does Bluetooth have to do with TMC?
TMC is a side channel of RDS on FM radio.
There is a software for showing TMC events at navifriends.com (called TMCview).

Those are very specific to the Eten hardware (and drivers). But its interesting nonetheless.
