Two methods to disable Bose AudioPilot.. Is one really better?

[agentsmith988]

So the volume fluctuations from my Bose Symphony HU were driving me nuts. So I decided to do some digging and this is what I found:

Want the volume fluctuations gone? You must kill what Bose calls AudioPilot. There is a little microphone up in the sunroof console that picks up ambient noise in the cabin, witchcraft happens, and your audio equalizer is adjusted accordingly to sound nice and pretty. Sounds good, doesn't it? I don't think so... IMO, something falls on it's face in the witchcraft stage (especially if you have something like an aftermarket exhaust) and all of a sudden your nice Bose system is a possessed hunk of crap that will blast you with bass one second and practically go silent the next.

I know of two ways to do this:

-One is to simply unplug the microphone under the sunroof console (what I did). This gave me the results I desired, but I also get three quick beeps from my stereo every time I turn my car on (I don't mind it at all)

-Second, you could follow the TSB released by Audi and actually put effort into it (and not get any beeping)

After you do either of these steps, if you so desire, you can perform a vagcom love session with your radio, go to adaptation, channel 66, and activate the speed volume control so you can access it by holding menu on your radio (I hate this too, so I naturally did this step, and promptly returned it back to it's original setting).

-setting channel 66 to '0' allows you to access SVC from the menu of your radio and overall enables speed linked volume on your stereo
-setting channel 66 to '1' keeps SVC from appearing on your radio's menu and from functioning at all (IIRC, this is the default for the 2003 and newer Bose systems that have AudioPilot as part of the system)
See here for more info http://wiki.ross-tech.com/wiki/index..._II#Adaptation

After all of this, my question is... to the best of anyone's knowledge, is simply disconnecting the microphone and dealing with a few quiet beeps on start-up any less effective than going through the TSB from Audi?

Hopefully this helps a few people.. it's made it so I can bear using my DICE adapter (still have a wee bit of ground loop noise at high volumes that I can live with). All in all, if you've got a Bose system give it a shot and see if you notice a difference! I finally have consistent audio that I can enjoy! No more volume fluctuations or suddenly booming/non-existent bass!

I'd expect not. The TSB has you grounding the mic signal it appears, so either way the mic is disabled. The TSB will just get rid of the beeps since the HU won't sense that the mic is missing

Very interesting. Got your pm the other day btw. I'm going to try disabling the mic tomorrow and see what happens.

Mine is usually only bad when it's hot out so we'll see.

Exactly what I wanted to hear. Truthfully, I didn't look too close into the actual technical process of the TSB. I'd spent the time before working on this issue getting my Podi gauge wired up and thinking of splicing any more wires (after I saw the reference in the TSB) was an instant turn-off.

The heat always made stuff worse for me too. I'll be interested to see if it helps you out at all in your situation.

Off-topic, did you ever get the Dension adapter installed? I'm still trying to decide if I want to RMA my DICE adapter or try to add an in-line choke to try and get rid of the last bit of engine whine making it through my stereo.

Havent yet. I need to call AOA to get the radio unlock code, as the PO apparently lost it. But once I do that I'll get it installed and give my impressions. I'm hopeful it'll work as advertised and without the drawbacks we've both seen with the DICE units...

don't need the unlock code to disconnect/reconnect the HU once it's been unlocked, as it remembers your VIN and verifies it with the cluster (via CAN), only requesting the unlock code if there is a mismatch

neat.

I wondered what the mic was for up there... I also always wondered why the audio system sounded better with the engine off.

I know thats how it should work, but when I plug in the Dension box, it asks for the unlock code. When I unplug the dension box it works just fine again. I'm not sure the reason exactly, but I need the unlock code to get it to authorize with the dension unit connected.

the Denison cabling has a pass-thru for the OEM wiring, correct? I assume it connects via the cd-changer interface, and it should pass-thru the CAN and line-out signals. If not, then that's why it's asking for the unlock code - bc the HU isn't able to communicate to the cluster via CAN

I don't know. The adapter is kind of janky. Its a but of a universal adapter. I was pretty dubious of it, but the guy I spoke with at enfig assured me it works fine. I'm going to try to get it connected tonight, the fiancé is hoarding the b7 to herself so I never get to drive it anymore, haha.

Your reasoning sounds solid though, I wouldn't be surprised if it wasn't passing all the correct signals. I might have to lookup some wiring diagrams and see what exactly it's passing through.

Hi everyone,

I am a owner of and Audi A7 year 2017 and other victim of Bose Audiopilot ...It is really auwful.

When I turn Up the volume the subwoofer looses its power...the bass really sounds weaker. It is really frustrating. I even installed a 10" JL W3 subwoofer (because 8" Bose with Audiopilot was nothing ) and Audiopilot kills this JL 10" subwoofer with digital amp...


So I desperated was looking for a solution and found this post.
I would like to identify the Audiopilot MIC and unplug It .

Other user from this forum made a guide ,

https://www.audizine.com/forum/showt...0#post14117150

However, my main worry is that the the user agentsmith988 made a comment (his First message on this thread) about the possibility to find problems with the Bose sound system even if you unplud the Audiopilot MIC.

He said something related to exhaust sounds...could make problems (I did not understand this really , what he wanted to mean)

But my A7 car has magnaflow exhaust (Stage 1 with downpipe) only you acelerate strongly un 2ns and 3rd Gear makes strong noisy, but the rest is absolutely normal, so


Is removing the Audiopilot MIC worth trying ??
Could I have problems because fue exhaust sounds ?

I would apreciate any opinion about it


THOUSAND OF THANKS!!!

You are in the B6 (A4) section so both the incorrect model and generation.

I highly doubt your system is similar to ours in any way. A few guys here might also have a newer A7 but I recommend going to the A7 sub for your generation car and asking there. Those folks will know what's up.

[Bardok84]

Thank you so much for answering me

Yes, I Will try just when I see chance to go to my nearest workshop (I do not know to open the pastic someroof by myself, although your pictures help a lot.

When I bought the car from audi Factory ,I ordered the A7 with Bose system and It was a Big error... From the begining I really missed the 8" subwoofer loosing strength ... I mean, when I turned Up the géneros volumen, I felt that the bass sound from the subwoofer went down..the bass sound was weaker...

Because of that , I disconnected the Oem 8"Bose subwoofer ( I Will put It for sale soon , even being new) and I bought a 10" JL W3 with a specific Woody box fitted an embedded in a side of the trunk with a digital amp amllifier connected. The change was definitely better, the bass sound now was so much bigger and stronger BUT, the same bss issue from the Audiopilot, made me sick... Again, as much as I turned on the volumen, It made the subwoofer sounding weaker again...

What a shame.

I do not know when I open the sunroof plastic if I Will be able to see clearly which is the Audiopilot MIC , hoping to see similar than this One of the following pictures I found in a tutorial. Even the car model is different , the Bad issue of Audiopilot is the same, It gives se kind of Hope .

Does Audiopilot MIC look like than yours?





Regarding the 3 beeps, se people say that they do not sound so much but sound low, is that true?? (I wish) and , during this time, Has anyone found the way to stop the 3 beeps??

I Will let you know the Next news, hoping to solve this situation.

Thank you so so much in advance for everything.


It has been my luck to find this thread.


Kind regards
