Thanks to this forum, I have had some success in updating my maps and speed cams on a Mazda TomTom NB1 system. I am now looking at trying to activate RDS/TMC here in Australia.

RDS/TMC service in Australia is offered by a company called SUNA. Up until 2009/10, TomTom units that supported RDS/TMC came with lifetime traffic service with SUNA. Then, for some reason (presumably licensing issue), TomTom decided to stop supporting SUNA ... BUT all previously sold units could continue to use their life long SUNA service.

So, apparently there are 5 files that if copied from a unit BEFORE TomTom stopped supporting SUNA - it is possible to enable RDS/TMC in Australia! I'm am unsure of the accuracy of this information.

The 5 files are:
<root directory>
mctx.dat
mctx.txt

<Australia Directory> (maps folder)
tmccodes.dat
traffic.dat
traffic.inc

The important thing is, these files have to be Australia 2009/10 vintage (before TomTom cutoff SUNA support) ... Or perhaps using files from another country where RDS/TMC is not disabled may work also??

Any expereinced members/moderators think they can help me source these 5 files. I'd love to try it out and see if I can get traffic fired up on my Mazda CX-5 (TomTom NB1 System) in Australia!

Note: my current maps folder only has 2 of these files:
tmccodes.dat
traffic.dat
