Thread: TMC problems for iGO Primo on Mio 6970LM.

Dear friends,

I think that the problem could be about some special setting of this specific model of Mio Spirit. If this is true, may be we could open a dedicated thread, if we will find a solution for the TMC to work. Let's see what I've discovered.

Let's forget for a moment about Primo, because I think the problem is not Primo, but the 6970LM.

I made a hard reset, put "protocol, 0" and so I started with the original settings of Spirit.

- I started the original software.
- I connected the TMC receiver.
- I waited for the TMC to work.
- I received some Traffic event.
- Then I started TMC_scan.

In this case, I would expect that TMC_scan works and give me some FM signal and so on. But no! It gave me the warning "Unable to access COM1!".

So, also referring to posts #6 and #10, I'm not able to receive FM frequencies. TMC_scan or crashes, or give me errors, and by the way the Spirit receive frequencies (also different frequencies), ONLY with the original software.

So, I take a look in the registry (HKLM\Drivers\BuiltIn\SW_TMC), and I se I have:

- Protocol > 00000000 (or 00000001, when I want to use other softwares)
...
...
- dll > "A5_SW_TMC"

This line, as I read, refers to the proprietary .dll used by the original Mio software (it is in "windows\A5_SW_TMC.dll").

I have no other models of Spirit, but may be this model works just (or only) with this .dll? Or may be that others iGO .dll must refer to this .dll as well?

By the way, if we solve the enigma of why the TMC_scan crashes or gives errors, we will find the solution! What do you think about?
