Thanks Don. Will keep looking.Originally Posted by DV52
snala: So - as I understand for the SUNA service (here in Australia, at east), the actual TMC data is transmitted over the commercial FM radio - it uses a harmonic of the stereo sub-frequency in the RDS signal (I think). The MIB unit (the module that lives in the glove box on a mk7 Golf) combines this information with the GPS data to locate the TMC data on the map that you see on the screen.
RDS also carries other data on the FM band - like the name of the song being played, or the weather information that is sometimes shown on some FM stations. So, if you have this information displayed, you probably already have a base level of this function activated.
Now we get to the difficult part - From my work with the MIB units on a mk7 Golf, I have found that the RDS function is enabled via Byte 13, Bit 3 on the 5F control module as per the VCDS screen shot below:
BUT - as you can see from the screen shot - there are lots of Bits on Byte 13 not shown with VCDS.
Here is a screen shot from my OBDeleven dongle for Byte 13 showing the Bit which refers to the same " RDS plus" facility as well as a basic RDS function and another reference to RDS on Byte 14 (boxed in yellow) - the reference to RDS plus on the second screen is a duplicate of that on the first screen
Unfortunately, there isn't an easy way of determining which Bits the OBD11 entries relate-to. So alas I can't make any definitive suggestions for your car. But you could try experimenting!

Interesting as I my brother in law and me had a tinker last night, He has the new 162TSI Tiguen so has been playing with that too and the two cars are a bit different. While mine has the 51 code for an Australian model my MIB unit is quite a bit different in spec overall as we were wondering why on the the radio settings mine doesn't show advanced settings as an options but everything else looks the same etc.
Driving over there last night I did however get one traffic message so it is in fact working so no TP reference as an option to disable anywhere but it did have the message and associated map. This morning showing nothing so I guess nothing loaded on SUNA this morning and I do wonder about the availability and useage in NZ too.
Another hint specifically for the 206 Passat only with LEDs currently and I would say 7.5 version Golf R and GTI is that when enabling light assist (which is pretty good I might add!) for cars with LED headlamps required a guess on the long coding that we couldn't see on our VDCS.
We had to change the longcoding in byte 2, last lines below, that was set at 1B to 1D. 1C which we could see referred xenons and light assist as below and looked like it was working until I tried it in the dark and I lost high beam.
So we tried 1D which wasn't an option we could see to select and it is working no problems.
To Activate High Beam Assist (Light Assist)
Open controller 09 - Central Electronics
Security Access 16 – enter 31347 and press Do It
Adaptation 10 – use channel drop down box, go to:
IDE08786-ENG116637-Assistance light functions-Menuesteuerung Fernlichtassistent
Change Stored value from Not Present to present. Press Do It.
Open Controller A5 – Frnt Assist / Driver Assist
Security Access, use code suggested by VCDS
Go to Coding
Open Long Coding Helper
Go to Byte 2
Use drop down box to change to Light Assist. Default is Inactive. Exit. Do It
Go back to the Central Electronics module, enter the security code
Go to Coding, Long Coding Helper
Go to Byte 2
Change from Bi-Xenon w/o Light Assist to Bi-Xenon with Light Assist, Exit, Do It
