The TMC data type is part of the FM data stream transmitted by the radio station.
Pioneer in there wisdom have left out most of the TMC code so you don't get much info. For example the TMC message is jut text it does not do anything
I have finalised the TMC mods for the new hybrid skin and am currently debugging the graphics. Included is the ability to exclude stations and manual tune. In manual mode you just tune to a station either by stepping up/down on the tuner or searching up/down. When you find a station it will search for a TMC data stream. Once if it is not found you get a "No Present" message. Once locked on you get the "TMC Present" message. After that it will change to the the Data type and key details. For here in OZ that will be GNS so you will get a message like GNS (Key present)
Hope that answers your question once released you are welcome to run the new hybrid skin or extract the tmc code. The code is a total rewrite of the OEM code. Include is the above plus,
TMC status icon on screen that shows up if the tmc tuner is present. The states are tuner searching for station, tuner locked on, has events, has events on route and has events on rout that can not be avoided
The options are
Sort events by, road, distance and type
Filter events by all or on route
Audible warning on/off
New event , auto recalc, off and ask
Advanced Recalc and Advanced show, these allow you to turn on/off recalc for each event type as well as hide the tmc sprites on the map by type
TMClist on map, this gives you a scrolling list of tmc events on the map display. You can select how many lines (events) to show, how it is sorted and filtered. IE if you have 2 events selected, on route with the distance sort. You will get a list of the 2 closest events on your route. If you press the box it will take you to the event list. A long press takes you to the event on map scree detailed below
Pressing the TMC status icon will bring up the event list.
From the event list you can jump to settings, change the filter and sort
Pressing an event will bring up the event on the map. You can select to allow, ignore, avoid and unavoid and zoom
