TMC problems for iGO Primo on Mio 6970LM.

**vesijunu** · 9th May 2018, 02:33 PM

Ok, Boki-Srb, now I tell you exactly what I make and what happens.

1) Power ON, the minishell loads, the autorun detects the SD Card.
2) I make an Hard Reset, to be sure to start from the beginning.
3) I repeat the #1
4) I start regedit, and check that HKLM\Dirvers\BuilIn\SW_TMC is set to 1. I't' Ok, it's set to 1

Now I connect the TMC antenna and wait some minute. Then:

5) I start TMC.exe
6) The menu "set COM-Port" appears
7) I select COM1 - (\Drivers|BuiltIn\SW_TMC) - I press OK
8) The window "FMx-Control (COM1)" appears
9) I press the arrow of the "TunerControl"

And after pressing the arrow:

10) I receive the warning "No reply from Module"

The antenna is connected, the protocol is 1, the antenna is functionally. What other is missing?
The problem is not depending from iGO, I think, so may be we need some more setting to activate the reception of the signal.

What other? Something to modify in the registry? Some script to activate FM reception? Any other idea? This is the main point!

Bad news
Your device is new. Enough new that there is no driver for tmc for WinCE (and iGO). New version of receiver.
It is not first time a see case like yours, but on some other devices.

vesijunu and Boki_Srb

The TMC in vesijunu Mio 6970 works with original software:

-

--> costas3850, I think this is the central question! TMC_scan gives me error, like if I had no TMC receiver! But in effect, I have, and with the original software, I receive traffic information.
So, the question is:
1) I have SW_TMC protocol=1 (and now also RadioEnable=1).
2) I have a TMC receiver that works, because with the original software (with protocol=0), I receive traffic informations.
3) I have all the .dll and licenses (thanks Boki_Srb for all files).
4) iGO runs very well on routing, being the TMC the only problem
Is it possible that the TMC (but with protocol=0) works ONLY with the original software? Is it really impossible for my 6970LM to have the TMC with iGO?

I think original navigator in Mio 6790 works under Windows CE. So, The OS does have the necessary driver(s) for TMC receiver.

I think the point is: what is the path for this (these) drivers in Mio 6790 WinCE?
If anyone can access the OS and find the path and clone in mortscript script...

No. There is driver for Mio software, in Mio software.
On some new devices I've seen new GPS chip receivers, which are working under current software, but no iGO recognize them.
There is high possibility that here is similar case. Very high.

vesijunu, it's not enough just to to set to 1 value HKLM\Dirvers\BuilIn\SW_TMC .
You must also do soft reset.
[Only registered and activated users can see links. ] MioAutoRun\Apps\TMC\TMC.exe write the registry key and make soft reset.

Dear friends, I see the problem is really serious!

Yes, may be that the device is really new, and have no new drivers, why not! But I think that Mio Technology has intentionally disabled some option and want to complicate the life of users (Mios are the best for unlockers)!

In this new series 69xx, for exemple, the SD autorun was not implemented, and the problem was solved with a script. So, may be at the same time it was not implemented the FM transmission, and we need another script or some registry change for activating it. It's really a challenge!

By the way, hoping it can be useful, I want to share what is into the registry, in:

HKLM\Drivers\BuiltIn\SW_TMC

Spoiler: HKLM\Drivers\BuiltIn\SW_TMC

I hope little by little to found a solution!

As I said...no driver for iGO...
You can try next: find that exact dll (A5_SW_TMC.dll), in system or in MIO software package, and copy it in iGO folder...
But, I sincerely doubt that it will work

Vesijunu

Edit the script you use to activate TMC receiver:

Try this:

Notify = RegRead("HKLM", "Drivers\BuiltIn\A5_SW_TMC", "Protocol" )
Notify = RegRead("HKLM", "Drivers\BuiltIn\A5_SW_TMC", "RadioEnable" )
If ( Notify = 1)
Run "\SDMMC\TMC.exe"
EndIf
If ( Notify = 0)
RegWriteDWord HKLM, Drivers\BuiltIn\A5_SW_TMC, Protocol, 1
RegWriteDWord HKLM, Drivers\BuiltIn\A5_TMC, RadioEnable, 1
Sleep (1)
Reset
EndIf

Notice the A5_ difference in script
copy TMC.exe to SDMM root.

After that, try to use the app TMCscan and see the results.

Note: In 2015 there was already your gps model. It is not a new model.

Primo stops general developing in 2014 (actually 2013, but for some large cooperatives continued a little bit). No new drivers and support.
I've seen devices in which iGO did not recognize GPS receiver at all!

Good luck with all proposals and attempts

Hi again.

Boki_srb, I tryed to copy A5_SW_TMC.dll, but I received a prompt to overwrite, like if it were also present. And this I received everywere I tryed to copy.

luizcarlosrio, I also tryed with radioenable=1, but it was the same. About A5_TMC, I have not this key in registry. So, do you means to create it?
