I have a couple of versions of the 9.13.405512

I connect my Chinese 2DIN HU via Wifi to my 4G phone and get TMC with both versions.

When you press on the TMC button in the top right corner;
v1 - gives me a list of events and shows them being updated
v2 - shows an overview map of the country i am in with the traffic status over all the country.

I looked in the ux directory in all the zips and in the content skin directory but for the life of me, can't figure out what is providing the overview map.

I want to use the evoskin with the overview map. Currently i get the evoskin with v1 and if there is a traffic delay, pressing the tmc icon bring a map with the detour options, but doesn't give me a country traffic overview.

Any way you can post a picture of the TMC screen? It sounds like you either have a UX file (which you said is not the case) or that you are using some other non-standard skin already (check in the Settings->Display menu).

only two things in the build with the overview map are;
ux\iqs.zip
content\skin\diMka-WA-P171 Urbexuk-Mod.zip is

will try to post pic in the next days

Then I'm guessing that TMC overview map is a function of that skin (assuming you have that skin "activated" in Primo).
