View Full Version : Can the FM receiver be used as a TMC?

I'm wondering if the RDS data output of the FM receiver can be redirected to a virtual COM port to be used as a TMC receiver with GPS programs like destinator 7.

even if it was possible then the reviewer said that it only worked when the headset was connected guess it act the role of antenna would be bothersome to have the wiredheadset hanging while using it as gps

Hi Rudegar, great to see the red/white flag ;-)

Headset vs. FM antenna can be handled software wise.. eg. on Eten G500
As soon as headset is plugged a popup asks to redirect sound to ext. speaker for navigation purpose.

As for the TMC / FM radio in HTC products.. (Polaris, Artemis etc.).. Haven't seen a solution yet, RDS is supported in both products, so if TMC mesages runs on the default RDS stream it should be technical possible.

I don't think that this could be a problem: I'm thinking on connecting the device in my car with a "Y" connector, one of the outputs to the sound system (car radio) and other to a power system. It is easy to connect the car antenna with a capacitor to the sound line.

Then the Device will be connected to a external headeset, with good antenna capacity, and at the same time to the car power.

Yes, TMC is only a filtered data stream of the RDS network. Obviously it will be needed to know the correct RDS chain that works in each country for TMC, but it is only information.

The question is: Is there any known way to extract online information of the RDS data from the FM receiver programatically?
I can do a program that attach to any API or hardware interface and present the data in a virtual port.

Well, i can't help you too much but i remember that some time ago, perhaps a year ago, hackers been cheating on RDS and people been foolish when reading on their car radios notices like "alarm because of ..." . I don't remember also wich country, perhaps Australia or Usa.

I also remember that, but I'm talking of the opossite side of teh RDS: Trafic information is sent like these RDS hackers sent their "information" but in a data format called TMC. Inserting this RDS transmited-TMC coded information into some GPS navigation software helps the software to create optimized routes.

I've seen the Polaris manual and the FM receiver is RDS compliant, then the RDS data transmited over the FM modulation is decoded iniside the Polaris and shown in the screen. But: If we could extract these RDS information from the decoder and make it available in a serial virtual port, then GPS navigation software running in the polaris could take advantage of it.

I need the FMS_API.DLL, then there is TMC/TMC Pro !!!

from what I've read most navigation software support combined gps/tmc on the same com port. this means someone should extract also the gps data and combine both...

At least Destinator 7 supports two separate comports for GPS and TMC.

it must be changed gpstmc.dll. but the FMS_API.DLL penetrate needed!!!
