Hi everyone,
I need Your help, I have problem with TMC not working on my device F700BT. I try to add some mod to sys.txt in Primo etc .. It doesn't work!,
I scan com ports in TEST mode to find out  com port where TMC signal is, but program hasn't  find any COM ports with TMC signal

so my question is:
Do I need ANY special antenna to TMC working on my device?

OK, I've scan COM ports again in Test mode with GNS TMC.exe, and I found TMC signal at COM port 4

When I run GNS TMC.exe (not in Test mode) but in normal mode from avic menu-  access to this port is restricted !

I am trying do run TMC in iGo Primo, but in the same time I have running standard iGo (btw. in iGo I also don't have any TMC, only scanning frequencies)

so

How to release COM port 4, THAT IGO Primo has access to it

edit:

I have on my F700BT this soft : AVIC Net 2.0 EURO VERSION: http://avic411.com/index.php?/topic/32763-avicnet-21-for-avic-f-series-working-obdii-updated-041812/

Hi

There is simple way to bypass iGo using COM4. In SYS.TXT in iGo folder file add:

[tmc]

source="gns"
port="COM,8"

Restart system and igo will set igo TMC port to COM8, by the way not used. Now COM4 is free:))

To be sure it will work with your Primo or other NAVI add in SYS.TXT in PRIMO folder:

[tmc]

saved_config_available="1"
saved_config_classname="GNS_GPSTMC_SOURCE"
saved_config_portname="COM"
saved_config_port="4"
saved_last_tuning_mode="1"
auto_tuning="1"

Have fun

Sorry

BUG DO NOT CHANGE SYS.TXT in igo. It blocks port for BT parrot. Found this when fixed avic in car & tried connect phone.

Sorry once more.
