Has anyone messed around with upgrading the sound system on our e-trons? I don't have the Bang & Olufsen or know how it sounds.... but to me the sound is a little off in the car.

Not necessarily distorted, it's like I'm missing depth, clarity, and details in whatever music I play. Anyone else feel the same way? I don't usually mess around with car audio so I'm a little out of my element for where to begin.
Not sure what year car you have...

Play a good high quality lossless audio source and then press these buttons in the centre console > menu-center dial-and button under "media". Press them all together and release. This will reset the MMI. If the sound quality improves you'll need the software update that fixes this issue.
