I already had V9 when I took delivery of my new P3D+ but just updated it to the latest version w/ dash cam and navigate on autopilot and notice the sound system dramatically changed. It doesn't have that "punch" as it use to. I check the EQ and it's still on the same settings it was before the update and I played the same playlist as I did prior to the update as well and it just sounds a little stale. And yes, immersive sound is still on. I checked to see if I was the only one and it looks like others have started several threads of this last year til the beginning of this year but only for S/X. Haven't heard from Model 3 owners yet. Anyone else feel the same?
