addition: is there a setting in sys.txt that gives more choices maybe?

No, No, this is the phone settings.
You need to look for "3G service".

about your another mentioned check: traffic volume of 50Mb is included, so thats enough

ok, yes i can switch on/off 3g on my phone. it is on. When i lose wifi, it then switches automatically over to 3g.

Check that you have this lines in your sys.txt:

[tmc.src.http]
enabled=1
[tmc-http]
enabled=1
start=1
servers.size=3
servers[0].url="http://zippy.naviextras.com/services/tmclite/data/nng-igo-tmc-iphone/0/"
servers[1].url="http://zippy.naviextras.com/services/tmclite/data/nng-igo-tmc-russia/0/"
servers[2].url="http://tmchttp0.naviextras.com/nng-igo-tmc-primo/0/"

yes, 100% the same

I find maybe something..

i have the version "Primo 2.4 (9.6.29.383117) Android ("for Israel") [3.Apr.2014]"installed.

i see in the igo directory also a file called ux. This is a Winrar file. What to do with this file? Normally there is a ux directory.

UX folder should be in the root of the program and contains "zip" files.
I'm not sure at all that this is your problem, since I had previous versions without this folder, and traffic alerts was working.

you're right. This isn't the problem. I renamed it to test without ux folder and problem still exists.

In discovered something else. When i install the .apk again (after delete save folder, and uninstall .apk) then the sys.txt is overwritten by a "default" sys.txt. I think this sys.txt is embedded in the .apk?

Some information/parameters are saved by installing the .apk at an location on the mobile in dir data/data. You can see this only if your mobile is rooted. my mobile is not roted.
I have seen that in some sys.txt the line: servers[1].url="http://zippy.naviextras.com/services/tmclite/data/nng-igo-tmc-russia/0/"
is commented so it doesn't work. I did this also in my sys.txt. Nothing happening, but may be is still some parameters in data/dat left.

What i need i a clean .apk (|without filled sys.txt) so i know for sure that settings of sys.txt in directory Igo will work.

My device is not rooted, so I have no idea what you are talking.

The line "servers.size" in sys.txt (above servers[0]) is pointing about how many servers is active. If the line above is commented, and you have only 2 active servers, this line should be like "servers.size=2".
If all 3 lines of servers are not commented, make sure this line is "servers.size=3".

You can find here a version that does not create sys.txt when installed. See here my summary about the different apk files of this version.

this is nice. I am going to install this .apk and test it.

I will let you know.

ok. bad news. didn't solve the problem.I am getting crazy. I don't know anymore what to do now.
At start up it loads the same traffic data via internet and after that no refreshes anymore.

Sorry to hear that. If any idea will popup, I'll let you know.

thanks. Now also tried on a HTC and a Samsung S2 (= also different networkprovider). Same problem. It must be somewhere in the iGO software. But why is it working on your phone? Strange. I tried also navteq in stead of teleatlas maps.
Maybe i can get a zipped iGo version of your phone? Then i can trace the files if there any difference with my installation. Else i wouldn't know anymore

I was sure you're using my version. It is not?
You can get it here.
