In 2017, auxiliary jacks are super-duper cutting-edge high-tech ultra-technology of the future

In case you didn't know that.  Some would argue that auxiliary (AUX) jacks are 1930s technology, but we have a 2017 Chevy Impala with a state of the art entertainment console/module/something, and the AUX function doesn't work.  It's that simple.  It doesn't work.

Simple logic tells us that, if an AUX function doesn't work on a state of the art, super-duper, ultra-modern, latest-technology entertainment console, then it must be, at the very least, emergent technology.

At any rate, it was working yesterday.  The console "detected" my AUX device (a Panasonic portable CD player plugged into the AUX jack), and I was able to play CDs and stuff, and everything was great.  Today, no device was detected.  No sound.  Everything was as I had left it, but no detected device, no sound.  None.  Nada.  Zilch.  Nicht.  Zero.

So I plugged, unplugged, turned the car off and on again, tested the Panasonic player in the house (it's working fine), then counted to ten to keep from smashing something in anger.

Worked yesterday but not today.  Who to ask for help?  Well, given the fact that the folks at the dealership, including a tech, are less familiar with the console/module/something menu that I am (picture a tech poking around, with no idea what he's looking for because Chevrolet forgot to inform anyone what they were planning to do with the 2017 Impala command center console thingie), going back to the dealership would likely be an exercise in, "Hm.  We don't know what's happening," only it would take 20 minutes to get to that revelation, and meanwhile everyone would act like they knew what they were doing.  And there's no number to call.

And imagine if there was a help center.  Person on phone (heavy foreign accent): "Do you have the device plugged in?"  Only, of course, it would come out, "Do you haf dee (inaudible) plag een?"

Here I sit, defeated by the auxiliary function.  Back in 1955, Bev, who is going on 83, used an AUX jack to listen to her record player through her radio.  In 2017, I can't use an AUX jack to play my Panasonic through my super-duper, state of the art, emergent-technology entertainment audio console/module/whatever.

1955=plug player into AUX, sit back and enjoy the sound.  2017=No device detected.

Progress.

UPDATE: Working again.  But... for how long?  (Ominous music, fade)

UPDATE, PART 2: Continuing to work.  It's messing with me!
