    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.

    It would be great if we could have option 3

    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

    As I said previously my signal drops out frequently and there seems to be no signal in regional cities.
    I am very grateful to get as far as we have and thanks to Simba for doing the work and Poshea for testing.

    Finally installed my version of ttsystem combining simbas patched navcore with deadbeefs mctx (option 3). Installed perfectly on my mazda - all working and I'm still getting traffic here in Sydney. So this custom navcore should work with traffic in all Australia states/territories and will tune to either SUNA or HERE traffic data (whichever it finds first).

    Enjoy. Please report back how it works for you.

    I installed poshea's ttsystem file tonight and all seems good.
    I will see if the Traffic drops out in the same areas it did before over the next few days.

    Mazda 6 NB1 2013 -2015 TomTom CX5

    Thanks for your effort guys.

    Edit
    Okay I've had it installed for a couple of days and driven around Melbourne without any drop-outs. It does take a while sometimes to appear on the screen at start up, all good and a real success.

    Some others have reported traffic dropouts in some parts of Melbourne. I don't think anything else can be done (software wise). This navcore is unlocked in all parts of Australia with both traffic providers. My guess is that some parts of Melbourne simply have weak reception of the traffic channel. It's also possible that some car models may have slightly better/worse antennas to receive the traffic data thus effecting reception.

    From the SUNA website:
    I could not receive traffic reports on my device today – is there a problem?

    SUNA is broadcast using FM technology and occasionally devices may experience drop-outs. Transmission ‘black spots’ can affect reception, especially in very dense urban areas such as CBD, and terrain effects, (e.g. valleys).

    In my 2013 Mazda CX-5 (Sydney), the traffic bar appears...not always instantly - but fairly soon after I begin my trip- and I have driven all over the city including quite far west - and have always had constant traffic data. (No dropouts).

    If I ever drive through Melbourne or Brisbane I will share my experience.

    Thanks guys.. just drop this into the SD and put it in car? and then traffic should just come automatically? or some setting in tomtom as well in car?

    Is there way to hack the tomtom map to get latest Australia map as well?

    You can combine your running NB1-Australia-Map with the PNA-Australia_966_7373 and activate this combination about the Australia-100736.meta from the PNA-map (delete the NB1_.meta and NB1_*.dct).
    Leave all files and folders from the old NB1, who are not in the PNA-map. All others files take from the PNA-map

    Hi Poshea,

    just noticed that Simba has released the new core 10.855. If I updated, am I gonna lose the traffic bar as it was not patched with the mctx.dat file?

    Thanks
