How much of that noise is fake?

If Caddy added this as an option I would have paid extra.

Added a 12" sub to my 5V tire well and it was immediately obvious the sound was being piped in. Look at my last 2 threads on how to disable. I didnt notice before aftermarket stereo but im a naturalist and once I knew it was electronic sound I felt like I may as well buy the new Charger EV. (Kidding).

Id just rather have the car be the car and the sounds be the sounds. And with the corsa on the way and stereo in, it was necessary to change it back how my 2 2nd gen Vs were. Au natural.

This product was mentioned in a non-BW thread I ran across. Any thoughts on this sort of thing?

LLJ ANC bypass harness

When it comes to adding aftermarket equipment in todays modern rides you will come across ANC or Active Noise Cancelation. This is the process of introducing antiphase to the interior of the cab in an attempt to combat ambient road noise or wind noise. The main problem comes from adding low bass...

I prefer this approach because it's easy to reverse if desired.

However good luck ordering one! I put in an order last Friday. It did not ship and Monday I got email that it had been canceled "because we did not have enough stock to fulfill your order and your payment has been refunded." I emailed them on Monday -- no response. Note that even now the harness is shown as in stock and available to order... I tried calling them today but got a recording (and a robo txt message) telling me to txt or email them. I sent a text asking how to order -- no response.

If I can't get one from them I might try PAC or Metra/Axxess but I'm not 100% sure either of them have an application for the UQS radio.

(And I would roll my own but while the female connector shell is available (35016343) it appears Aptiv never made a free-hanging cable male connector shell.)

They finally got back to me, they say they're out of stock for another two weeks. Apparently they don't let orders sit around unless they can fulfill them within 5 business days.

Looking forward to your results!

They finally got back to me, they say they're out of stock for another two weeks. Apparently they don't let orders sit around unless they can fulfill them within 5 business days.

So I waited two weeks and asked if the harness was back in stock. No response so I ordered one. Order was canceled and refunded the next morning. Sent messages asking what's up for the next three days. Finally got a response today: still sold out, will be back in stock in three weeks.

I'm not optimistic I'll ever get one of these...

I cant remember where else I mentioned this but at the bottom of my stereo install post, I solve this problem for free in 30 mins.

Adding this to this post too: ANC issue solved. I dont like cutting factory harnesses. I also read that on Older Vs if the ANC system sees a fault, it disables completely. There are 3 microphones in cabin. 2 of them are driver and passenger side just over your head, hidden under the grab handle at the top of the door. One is dead center between the 2 rear passengers.

I wanted to remove 1 mic and test. I pulled the rubber door trim down, popped the 2 plastic covers off that hide the bolts on the driver side grab handle. Used a 5/32 socket and removed the grab handle.

Next, I carefully...

What noise we talking about? My better half has been given me fake noises for decades?

IDK, with the windows rolled down something real appears to be happening.

It's been three weeks so I sent another message today. Surprise! They are still out of stock. I was able to confirm that the part number is GMBB4. They did not give me a new ETA (nor would they answer why this item is shown as "in stock" on their website...)

The Chatbot gave about the same answer. Said it would be available in 2 weeks.

I ordered that one. Ordered April 30th and shipped May 5th. They did send an email letting me know when it would be going out. Overall the customer service was good and it got to me within a reasonable amount of time and the product does work.

I think so. The price is the same and the phone numbers both have Phoenix, AZ area codes.

The Chatbot gave about the same answer. Said it would be available in 2 weeks.

They've been saying that for six weeks...

I was looking for the correct de-pin tool instead of the bypass harness. The price is more than the bypass. I hope they restock soon.

Figures. I ordered one on May 9th and they canceled/refunded the next day.
