2016 XC90 Inscription purchased in late 2015.

Recently received Sensus software update. Afterwards, B&W sound is degraded. Adjusted all possible sound settings (balance, fade, bass, treble, subwoofer, equalizer, sound experiences, etc). Sounds more like a rental car stereo than it did prior to the update.

Service department checked it again, and pronounced it fixed with "adjusted bass settings". Still not back to original rich, full sound.

A few days later, the stereo paused momentarily, and original sound was restored. in the meantime, it has returned back to the rental car, "tinny" sound.

We even had the service rep listen to ours side by side with another model with B&W system, and there was a noticeable difference.

Any suggestions? Software issue? Loose connections?

 

Hi Mate,

Did you ever fix the issue with the tinny sound? I have a 2016 Volvo XC90 with Bowers & Wilkens and the amplifier died on me, so I just got a new one, but I have no bass/subwoofer/treble and nothing happens when I try to adjust the sound.

I am thinking my new amplifier is faulty, but I am keen to hear how you sorted your issue.

Kind regards,
Kevin

 

Hi Kevin

I own a Volvo XC90 2016 R-design with B&W soundsystem.

Did you sort out the issue?

Ive got the exact same problem as you..
got a new amplifier because the old one died..
and now i cant adjust anything..
it doest react on the sliders for bass, treble og sub..
and its lacking bass.. it sounds like the sub is turned all the way down.

Hope you can help me.

Best Regards
Dennis

 

If the sound goes back to its original quality, it might indeed be a software problem.

Also, check the wires and connections for the audio system.

And I’d check the amplifier unit. Sometimes, issues with the amplifier can cause fluctuations in sound quality.

Maybe, try resetting the car's system to fix the issue. Disconnect the battery for a few minutes.
