Humm... I've not been having much luck with changing the mctx.dat file.
Can anyone upload the uk_trafficmaster.dat file as Classic FM reception in my region is abysmal.
I know a few have worked out the structure of the mctx.dat, can it be manually edited so you can compile your own?

Hi, I am newbie on file mctx.dat, but have applied the brute force to extract information of encoding, and the final file encrypted.
There my step
file mctx.dat
mctx.dat: Non-ISO extended-ASCII text, with CR line terminators
1)script
iconv --list | sed 's/\/\/$//' | sort > encodings.list
for a in `cat encodings.list`; do
printf "$a "
iconv -f $a -t UTF-8 mctx.dat > /dev/null 2>&1 \
&& echo "$a" >> success.txt || echo "$a" >> fail.txt
done | tee result.txt

execute first script and get type of encoding (success.txt)
2)script
for a in `cat success.txt`; do
printf "$a "
iconv -f $a -t UTF-8 mctx.dat >> folder/$a \
&& echo "$a" >> success.txt || echo "$a" >> fail.txt
done | tee result.txt

execute second script and get all the content of mctx.dat on folder (559 file)

for reverse (recompile) change the command iconv option on preview script.

Okay... I'm getting nowhere fast :(
I'm still looking for a comprehensive mctx.dat that cover as many RDS-TMC data providers as possible of includes support for Trafficmaster in the UK.

On my old GO 910 I changed the mctx.dat from 22220 to 11110 (the Trafficmaster network I believe) and it made a massive improvement to the RDS-TMC in the UK and across Europe... it was very useable.
I was hoping I could do something similar on the 940 to improve the RDS-TMC as I get bugger all at them moment.
I would prefer to use the USB 4V00.014 option on my 940 as the antenna on the RDS-TMC active mount is tiny and I have a heated front windscreen.
The connection to the GO 910 was a far more elegant and thought out solution.
P.S. I don't want a Live subscription as I can get detailed traffic information from Google Maps should I need it.

Yes but when 2 or more providers are available in the same area (ie. Trafficmaster and ITIS/INRIX in the UK) and you have both in the same mctx.dat file, the receiver will simply pick the service associated with the first radio frequency it can tune to (ie. the lowest FM frequency in most cases).

Hi again, apologies for the triple post but I've created a "master" mctx.dat which will enable all the known services that are natively supported by TomTom devices. In countries where there are more than 1 provider, the first FM station (and associated traffic service) that the navigation unit can tune into is selected.

Enabled RDS-TMC providers:
  • Australia - HERE Traffic [VIC, ACT, NSW, QLD, SA, WA, TAS, NT]
  • Australia - Intelematics (SUNA) [VIC, ACT, NSW, QLD, SA, WA, TAS, NT]
  • Belgium - Be-Mobile
  • Canada - Total Traffic & Weather Network (iHeartRadio, formerly Clear Channel)
  • Croatia - TrafficNav
  • Finland - MediaMobile (V-Traffic), previously Destia
  • France - MediaMobile (V-Traffic)
  • France - ViaMichelin
  • Germany - HERE Traffic (DE), previously TMCPro
  • Hungary - TrafficNav
  • Ireland - TrafficNav
  • Italy - Infoblu
  • Luxembourg - Be-Mobile
  • Mexico - Total Traffic & Weather Network (iHeartRadio, formerly Clear Channel)
  • Netherlands - ANWB
  • Netherlands - Be-Mobile
  • Norway - MediaMobile (V-Traffic), previously Destia
  • Poland - MediaMobile (V-Traffic), previously Destia
  • Portugal - TrafficNav
  • Puerto Rico - Total Traffic & Weather Network (iHeartRadio, formerly Clear Channel)
  • Romania - TrafficNav
  • Slovenia - TrafficNav
  • South Africa - Altech Netstar
  • Sweden - MediaMobile (V-Traffic), previously Destia
  • UK - INRIX, previously ITIS
  • UK - TrafficMaster
  • USA - Total Traffic & Weather Network (iHeartRadio, formerly Clear Channel)

EDIT - 7th June 2019 - Added support for HERE Traffic in Australia with the correct decryption key - the one supplied by poshea/deadbeef is incorrect.

roflmonster... you're a star!
Using your super mctx.dat file my TomTom connected to a TrafficMaster enabled radio station in minutes.
Can't wait to try it out on my next drive across Europe.
Thank you so much :)

Your work is very much appreciated, but I'm a little confused... how come the new file (7th June 2019) with the additional/corrected Australia TMC provider is half the size of the previous mctx.dat file?

There were some incorrect/redundant services enabled for US/Canada which I was able to better fine-tune with the help of some external sources and cut down the file size.

Great... that explains that mystery :lol:
The first comprehensive mctx.dat file you created has been working perfectly... the RDS-TMC on my 940 locks on almost immediately and stay connected.
Before using your file it never connected as the reception from ClassicFM station in the UK is useless pretty much everywhere.
Once again, thank you for taking the time and making this available to us all :023:

Hello.

So you simply change the file on SD card (Tomtom carminat 8.843 "prepared" and with no wekk rollover bug) and that's it!
If that is so, you are a genius. Million thanks, i will try on my Renault Megane 3 and then let you know how it works on Portugal.
Do you know what radios / freq. that are transmitting?
Thak you again.
