Hi VANomad,
I got mine done on Friday and also see 18AA-1945-001.
In the interest of accuracy for the benefit of future readers, I'm going to disagree with your assessment of the update. It's nothing personal and I'm certainly not the absolute authority on this so if someone wants to correct me; please do!
I'm under the impression that there shouldn't be any changes to the operation or sound of the audio. It was defined as a fix for backup camera and HUD glitches only. In some cases the backup camera would not display and/or the navigation in the HUD would not display until the unit was reset. A safety recall as opposed to an OTA update.
What it did do to mine is reset it to factory settings which means that the equalizer, fader, and associated settings are all back to default. Could that be why it sounds different to you?
It also should not have had an effect the camera appearance. Maybe there too a "view" has been reset to default.
I have no experience with the hybrid settings and screens. Perhaps those too have been adjusted.
