Hi pyro2677,
I would not suggest manually tuning to a station. Leave this off so the system can auto scan and find a station broadcasting traffic. When it finds one, the traffic bar will appear...even when there is no active route. Traffic information on the traffic bar will appear when you have a planned route with traffic on it.
Are you on the outskirts of Brisbane, or in the city?

This is the Suna coverage area in Brisbane. when you drive out of the zone, the traffic bar would disappear.
We have determined it is the mctx.dat file the 'enables' RDSTMC in certain zones. The mctx.dat used in simbas post above was sourced from an old navcore (8.351.go530-go730-go930.CAB-navcore-GO) as old devices that run this navcore were listed as supported devices on the SUNA website). It certainly works in Sydney, and I believe another member has reported it working in Melbourne. I'm not sure about Brisbane.
Since simba compiled the above ttsystem, deadbeef has had a closer look at the mctx.dat file we used and determined that it is only enabled in 3 Australian States, (NSW/VIC/QLD). If this is true, installing this version of ttsystem should enable traffic as you are in QLD (provided you are in the supported zone).
Deadbeef also determined that there is an alternative traffic provider in Australia called HERE. Hard to know which service would be better. I'm guessing they would get there data from the same sources, and therefore would provide similar results. SUNA seems to have added some additional regional areas, and since its been around longer - I personally trust it more... But it's really hard to know if one would be better then the other.
Deadbeef has provided 3 variations of the mctx.dat for AUSTRALIA RDSTMC
1) SUNA traffic enabled in all 8 states/territories
2) HERE traffic enabled in all 8 states/territories
3) SUNA and HERE traffic both enabled in all 8 states/territories
Note, tomtom can not pull traffic data from two sources simultaneously, so using option 3 would just mean it would use whatever radio station it finds first (regardless if it's broadcasting SUNA or HERE).
I have attempted to decompile the ttsystem and add the mctx.dat options above and recompile 3 different ttsystem files conserving all file permissions etc using Linux. I believe I have successfully achieved this, however have been hesitant to test. My system is already working perfectly where I am, and simba has more experience with working in Linux terminal - so I trust his version, not mine. I'm nervous if I made a mistake, my ttsystem might brick my tomtom!
The process is a little time consuming, but simba if you have time to make us new ttsystem files using the revised mctx.dat files provided by deadbeef, please let me know and I'll share the files with you.
