Hi, I have an issue, maybe covered before on the board, I searched & couldnt find. But I wish to flatten the audio signal on the head unit. I have a discovery pro 2.5 I believe & have the correct Vagcom settings in a link, but no clue how to work with ob11 & dont wish to mess anything up.
A link that explains with vagcom for an external MOST convertor, which I haven't purchased.
Anyone take the time to give me instructions with obd11 if possible, would much appreciate & I find head unit sounds not great with my external soundsystem.
Cheers.

infinite: hmm........ I'm not sure what you are asking! The instructions in your .PDF document explains how to enable the fiber -optics facility on a MIB (which uses MOST protocol). If you want to add an external amplifier, this is the same process regardless of whether you use VCDS, or OBD11. Meaning that you need to alter the same software switches on the long-code string on the MIB. However, adding an external amplifier involves other coding changes - for example, you will need to add the amp to the Gateway installation list and you will need to set-up the new external amp - which is a fully registered CAN control module in its own right (it's called J525 and it lives @ address hex47) Don

hmm...... to add to my colleague's sage advice - Byte 19 on the long-code string that you posted above has the value hexD6 = 11010110. I've highlighted Bit 5. You need to turn-ON MOST protocol - so change this software switch to 1

Cheers guys, that last suggestion from Don switched it back on.
Saved me a lot of stress.
Many thanks!

Were you ever able to get the Zen-V working? I'm kinda in the same boat... I know how to change the audio output to MOST with a VCDS, but cannot figure out the coding on OBD11. |

Jimmy: Hi. I'm not sure that I understand your confusion!! The process described in the .PDF link is the "normal" way of activating the MOST fiber-optic facility and switching-OFF the MIB's internal amplifier. The same function as the VCDS long-code helper screens as displayed in the .PDF link when using OBD11 is shown below
Maybe use more words to better describe exactly what aspect of the tweak you want explained using OBD11! Or, perhaps post-up the long-code string on the 5F module and I will tell you the new value. Don

The confusion was that I couldn't get the OBD11 to write the coding... but I've figured it out.
I have a 2024 RS6, which has SFD2 encoding protection.
OBD11 is not able to write anything onto the newer VAG vehicles with SFD2.
The unit is kinda useless, unless they can sort this out...
I'm returning mine (bought it on Amazon).
Unfortunately, I also wasted a bunch of money on an Ultimate VAG Plan... don't imagine they will refund my money for this.

On the TaosForums they are using caristaapp evo to change throttle response, dash colors, locking of doors when they close the doors and unlocking doors when ending is turned off. Also changing brightness of lights and making the rear running likes as brake lights along with changing the 3 blinker to 5 blinker. When locking Taos windows roll up automatically stand so on. So I ordered it to see if it works if not I’ll just return it to Amazon. |

jimmy: hmm..........yes indeed - confusion explained!!
if you have a "2024 RS6" - why are you posting questions about this vehicle in the Mk7 part of the forum? Not all VAG model vehicles are built the same and a MY24 RS6 is designed very different to a MY13-MY16 Golf Mk7!!

Don, - I'm aware that we are talking about two different vehicles, but the MOST interface is the same on both. I was interested in the OP's application as it was similar to mine.
- For a Moderator, your responses are rather condescending and arrogant. Not sure why you feel you need to be this way... but I've read it in a number of threads.
- If you read my original post; I was asking for feedback from the OP - not from you. I was hoping he'd reply, as we are both installing an aftermarket Zen-V unit.
I'll admit, I made a mistake when I bought the OBD11 and didn't do my due diligence. I didn't even know about SFD2 until after the fact.
I've come to realize that the OBD11 will not work on my newer vehicle. It's a cool device... but won't work for me. I've moved-on and found a different solution. |

jimmydee : Hmm......OK, maybe my words were not sufficiently clear - my intention certainly was NOT condescension. If I wanted my reply to be patronizing - I hope that would do a much better job!! (I'm joking of course  !) So, my question really was a genuine attempt to understand your reasoning in posting on this part of the forum -which you have explained in your contention "the MOST interface is the same on both [models]".
As I said in my deemed "condescending and arrogant" reply" - your "MY24 RS6 is designed very different to a MY13-MY16 Golf Mk7"!! This is a very real statement and it most certainly applies to what you call the "MOST interface".
The fact is that when VW changed from cars that say were built with a MQB chassis (like the cars in this part of the forum) to the newer evo platform (which I assume applies to your MY24 RS6) - fundamental changes were made to the MIB design.
Of significance to your contention about the "MOST interface", cars with an evo platform are the first model from Volkswagen to be fully equipped with third-generation modular infotainment matrix infotainment systems. Without intending further arrogance, or condescension - this means that evo platform cars no longer use the optical fibre MOST bus. Instead, the Migration CAN bus is a new feature of the configuration.
Anyhow, its good to read that you have found a different solution

evo platform cars no longer use the optical fibre MOST bus. They do still use MOST for data transfer to the MIB3 controller... But they don't use it for audio output anymore. It is now an ethernet a2b bus for audio. The whole intent of this post (right from the OP's original post) was asking about recoding, so that we could get audio output through MOST (to run into the NavTV Zen-V unit). That's why I 'latched onto' this thread. In hopes that the OP might still be on this site and answer my original question. It can be done. I've done it on a couple of my previous Audi's using a VCDS. But with the new SFD2 protocol, it appears that neither VCDS or OBD11 are able to get past this. I have found a private shop (with ODIS) that was able to recode the MIB3 to give audio output through the optical MOST bus - into my Zen-V. |

Jimmy: haha..............let's not get into a tit-for-tat knowledge game - I'm sure that we are both far too mature for such antics!! Instead, I will acknowledge that your expertise about MIB3 is far superior than mine!
However, my statement referred to "the fibre optical Most bus" (emphasis on the word "bus" - being the primary part of the CAN topology) - but thank you for your ancillary information. It will be valuable to others reading this thread

The crazy thing is... they still run audio through the MOST network. But they have disabled it (via a software switch).
For whatever reason, they decided to transfer audio via an a2b ethernet connection from the MIB3 'brain' (located behind the glove box) onto the amplifier (located in the trunk).
I suppose they have their reasons for doing this... just not sure why. I suspect cost savings, as the newer RAM amplifier is significantly smaller than the previous MOST version.
I've done quite a few high-end audio systems. Always on German vehicles (my own). I'm not a professional installer, just an avid car audio entheusiast.
Not trying to sound like a 'know it all'... but, I've got a fair bit of experience with MOST - as it pertains to audio.
You can definitely still capture the audio signal through the MOST network, but it needs to be switched on... which is what I was hoping the OBD11 could do.
With that said; I was definitely stumped, when I first tried to fire-up the aftermarket system on the new RS6... and nothing happened.
That was the day I learned about the new SFD2 protocol...
I agree. Our banter back and forth may serve as useful for others (just ignore my 'bitchy' comments).

Jimmy: My guess is that the simple reason why "they have disabled it (via a software switch)" is because MOST protocol is NOT needed on the cars that you are likely to encounter (albeit I'm not sure what country this is!!) As I suspect you will be aware, the role of the MOST bus (again, emphasis on "bus") on the infotainment CAN on previous model Golfs was like this: Notice R78 in my picture as a component on the MOST bus. Now, I have never understood why moving vehicles need TV reception - but these modules are sold ONLY for MQB platform cars in the Japanese market (which has to be a very minor part of VW's world-wide Golf sales).
My hunch is that as a strategic economic decision given the likely sales volume of the TV module - rather than completely re-designing R78 for the new Migration CAN bus, MOST protocol was retained for this application (for "MOST for data transfer to the MIB3 controller", as you said in a previous reply).
However, because TV modules are almost certainly NOT available for mk8 Golfs in your country - "they have disabled it (via a software switch)"!!
