So I updated my 2017 Expedition with the factory Sony system to 3.4 using the manual method. Install was a breeze. When it rebooted did the full reset like instructed. All it really did was reset my audio settings… My audio sounded amazing for the first day. Now my bass is super muddy and sounds like a cheap Bluetooth speaker and my treble is super high.
My dual ac controls are also messed up. When it’s off it says it’s on. But when you turn it off, it grays out th button and turns it on.
Last my screen finally dims at night correctly. But now my back up camera doesn’t go full brightness like it used to.
Is there a way to ensure a full reset to see if that helps anything?
