Active Noise Control (EOE & EOR) - How to get it disabled?

[Pau1ey]

Hello!

I have a small problem and hope this is the solution
I work with aftermarket caraudio. My client has a 2023 XC60 T8, the car is equipped with a Harman/Kardon sound system with a subwoofer. The client wanted better bass so I installed a new sub box and amplifier.

It sounds great when the car is running on electricity, but when the engine starts, it thunders throughout the car and is unbearable.

Is it fake engine noise, or active noise cancellation that starts in conjunction with the engine and is played in the sub box?

Is it EASY to turn off the function? I have read that one should reset the software if the car is going for service at Volvo. Therefore, the customer must be able to reset/reactivate themselves.

Thank you 

Is the iDatalink Maestro RR/RR2 not available for it? You/ your client would need maintain a subscription to OrBit to tweak with it.
