I think the volume change as a function of speed is called autopilot, right?

In any case, is there a way to disable it?

If you have Bose that has a system called AudioPilot that changes the volume and tone according to interior noise levels, not vehicle speed. AudioPilot can only be disabled by cutting wires at the Bose amplifier in the rear of the car, and the RNS-E then has to be recoded to enable speed dependent volume (GALA/DSP). There is a TSB (Technical Service Bulletin) which describes how this is done.

If you don't have Bose the speed dependent volume is called GALA, but shown on the RNS-E as DSP. GALA/DSP is disabled by setting it to zero from the menu.

What is the problem behind your question?

Interesting. I have BOSE w/the RNS-E. I've tried every option under the DSP/GALA setting and it still adjusts the volume from standstill and cruising. :x

If you have Bose then the DSP/GALA should NOT appear as an option.

Sounds like either the TSB has been applied and AudioPilot disabled, or your adapter is not connecting the Bose pin to ground, or your RNS-E has been coded incorrectly.

Interesting! I know I have BOSE... and the wiring should be correct. I seem to be getting really good sound from my speakers (sounds a lot better than w/the stock HU). Maybe I ended up coding it incorrectly, but I don't think so? Which setting should be coded what for it to be correct?

Also, I've noticed that it only adjusts the volume when the sound is at a lower volume... the kind of volume you would set it at when you have passengers. Then it starts to adjust.

When I'm by myself and turn it up a little more, it doesnt adjust at all?

:x So confused!

OK, let's look at the coding. You've got an S4 with Bose so the RNS-E coding (STG 56, function 7) should be 309xyz (the xyz depends on whether you have phone, sat radio, CD changer, TV tuner, MFSW). The 9 tells the RNS-E you have Bose.

You should also check adaptation channel 8 (STG 56, function 10, channel 008), that should be 255 (AudioPilot on, DSP/GALA off) - I think you probably have a value in the range 0 thru 5 there at the moment - which is why the DSP option is appearing on your RNS-E.

To check the Bose pin you'll have to slide your RNS-E out of the centre console. Either visually or using a multimeter check that pin 7 on connector B is connected to ground.

Get those values and connection right and you should have just AudioPilot working and DSP/GALA disabled. On an S4 the best way I know to check that the AudioPilot is working is to accelerate in 6th gear from under 1000rpm, you should hear the AudioPilot increase both the volume and the bass content of the music as your V8 rumble gets louder!

Hm now I'm getting confused! :lol: I actually *don't* want the AudioPilot to increase/decrease the volume. I'm pretty sure I VAG'd it to disable the AudioPilot... but as I mentioned earlier, the volume still changes when at a semi-normal volume. Only when I crank it up does AudioPilot *not* kick in.

Just to clarify again:
US B6 S4 with stock BOSE
RNS-E added in... VAG'd to disable AudioPilot

On "normal" volume with others in car talking, volume increases/decreases when I'm accelerating/stopping. This is what I *don't* want... and want to get rid of! Adjusting the GALA does nothing

On higher volume when I'm cruising alone, there is no volume increase/decrease. PERFECT!

As I said in my first post in this thread...

AudioPilot can only be disabled by cutting wires at the Bose amplifier in the rear of the car, and the RNS-E then has to be recoded to enable speed dependent volume (GALA/DSP). There is a TSB (Technical Service Bulletin) which describes how this is done.

You need to read the TSB about AudioPilot (it's a pdf so I can't post it here but I'll email it to you if you want) - you CANNOT disable AudioPilot by coding alone.

What you currently have is both AudioPilot AND DSP/GALA active. So even when you set DSP/GALA to zero what you are getting is AudioPilot "doing it's thing".

If you get your dealer to apply the TSB and then set DSP/GALA to zero then you'll get what I think you want - no automatic changes to the volume.

Interesting, I assumed it was speed-dependent.

Either way, it's not so much a problem as it is an annoyance. I wouldn't mind the system so much were it "transparent," but it's extremely noticeable when it changes the volume.

I would prefer to not have any automatic volume controls at all.

Until the 2004 model year Bose was speed dependent (my 2003 B6 S4 had that version of Bose and and an RNS-D), but in 2004 they changed it to the AudioPilot system (which my 2004 B6 S4 is fitted with) which uses a microphone to measure interior background noise level and adjust the volume and tone.

Enough people think, like you, that the AudioPilot system is too intrusive for Audi to have issued a Technical Service Bulletin which tells dealers how to disable the AudioPilot system (it's a wiring change at the Bose amplifier in the rear of the car). I've only found it annoying on really hot days last summer when it increased and decreased the volume very rapidly until the aircon had cooled the interior of the car down (I'm guessing the microphone is affected by the high temperature).

If you want no automatic volume changes then tell your dealer that you want him to carry out Audi Technical Service Bulletin 91-04-17.

As I said earlier, I have the pdf of this TSB (it's 7 pages long) and am happy to email it to you (send me a PM) if your dealer pretends to not know about it.

Ahh..thanks PetrolDave! Now everything makes sense. I didn't know there were 2 different ways of the system adjusting the volume.

I'll definitely bug my dealer to get rid of it... but just in case, would you mind sending me the PDF?
