Traffic Reports with Discover Headunit

[SimoHDK]

There has been reports of some headunits not accepting this due to a software bug. As an example, my partners March-16 110TSI Highline doesn't work even after traffic being enabled in OBDeleven. As I read on another forum, this is a bug.

She's going to VW on Monday for a software update, I'll report back if it fixes the problem.

Hi all,

I can't seem to get the traffic updates to work.
I have made changes using OBDeleven and turned on TP setting but still nothing.

I noticed from video posted that I don't have the RDS option in my screen menu, second line is missing, does anyone know how to activate this in menu using OBDeleven?

Or am I missing something?

CandE; Hello. Not sure if you are aware, but RDS stands for Radio Data System. Just as a suggestion, have a look at the code-string on your MIB and in particular note the setting for Byte 13, Bit3. If the long coding helper is the same as mine below (which is from a MIB1), Perhaps this setting cab help you with the problem?

I've seen two cars where I was not able to enable traffic on Discover Pro (MIB2) units.
Both had software version 0240.
There is a TSB from VW which indicates that a minimum of version 0613 is required on these units.
Every other car I've enabled traffic on successfully has a newer version.
I'd suggest checking what version you have and getting VW to update per their TSB 91N9.
Then report back if it works.

^^^^ Kamold: Hello.

You may well be correct in your SW hypothesis (interesting observation). Coincidentally, I was investigating a problem for a colleague on another forum regarding the 5F module using OBD11 dongle and I came across the interesting long-coding entry below (highlighted in the yellow box):



Now the long coding helper screens on VCDS look very different to those on OBD11 and this entry isn't identified. There is also no way (that I know) of finding the particular Bit number for the Byte 14 RDS function that's quoted on this screen.

I hope that OP provides feedback because the solution for this problem is mighty intriguing!

Interesting stuff indeed!!

EDIT: On a totally unrelated matter, you appear to have access to some great resources which prompts me to ask the following question: Do you have ODIS and if so, is there any way of "hacking", or otherwise using the device to find-out the security access code for control modules?

I'm still on my quest to find the security code for MY16 instrument module and whilst I have been successful using VCP for this purpose (on other modules), I can't find an acceptable security code for the MY16 unit as the seed for the polling function (hope this makes sense)

[kamold]

Another piece of the puzzle perhaps Don...?
We'd need someone with a Discover unit with non-available RDS option and OBDEleven to check if that bit is set, then compare the long coding string with a working unit to see if we can isolate which bit might need to be flipped.

Not sure when I will see my recalcitrant Golf Alltrack again but if I do I'll check it with OBDEleven and report back.

EDIT: Just a clarification- the two Disco Pro systems that I haven't been able to enable traffic on both HAVE the RDS option available in the radio menu (and TP) however enabling them and setting the traffic adaptation to 1024 do not have the usual affect.

I have a sum total of about 40mins experience with ODIS but will have a look at it and see what I can figure out WRT security codes...

I made this change as suggest by Don, thanks for that, and now have RDS option in menu, but still not receiving any traffic reports.

What software version is on the unit?

I will check tomorrow and report back. Might have to get it updated as suggested and see how that goes.

CandE: Good- at least you now have RDS! The problem may well be the SW version as per Kamold's post, but one last suggestion that is an easy try is to reset the infotainment unit.

Not sure if you know this procedure, but just hold down the on/off button on the radio until the unit switches off and keep holding down the button until it switches on again.

When I did this on my MIB1, the initial value was 0. But on my mate's Golf MY15, his was something like 65535. I haven't changed his yet, but did anyone find changing from this initial value work? Or does it need a software update to his headunit?

[SimoHDK]

So my partner went to VW today, MY16 110 Highline. Hardware H24 and Software 0245.

No MIB2 updates available (Apparently one is coming...) so traffic obviously still does not work. Have not tried the POIs however I'm assuming they won't work either.

Need to do some research and find out how the software version numbering works.
Appears to be different for different regions.

MY16 92 TSI with MIB2 - H25.14.78 Software 0624. Updated early August. Traffic 1024 coded and custom POIs work fine.

[SimoHDK]

My personal car, MY16 Golf R is:

Hardware: 820
Software: 0624

Traffic and POIs work fine.

0 - dev options
32771 online traffic + VW TMCPro

Australia uses SUNA, I've seen lots of UK admaps that have 32771 setting. In answer to your question, I have changed a couple of units with 65535 and it has worked OK - but I needed to reset the MIB unit in each case and wait a while before the Traffic table was populated . On one of the cars, it didn't work until the owner started the car the next day - go figure!!
