New (to me) 2016 RP178

I have mine hooked up.  On a recent outage I went to Target and picked up a 6' RCA male to male stereo cable.  During that outing I just used the AV cable and plugged into the front AUX jack and just plugged the RCA stereo audio out on the TV to the audio for that cable.  When I got the Jensen stereo out, I looked at the back and discovered that the AUX 1 is AUDIO ONLY and consists of two RCA female left and right inputs.  It is marked as such.  I'm attempting to include a photo of this with that input circled.  I didn't get fancy with the cabling but just dropped it down so that I could retrieve it from behind the AV cable plate and just let the wire come out the side.  That gave me just enough to plug it into the back of the stereo easily and still have just enough to make along the plastic cable wrap and over to the TV audio output.  Works like a charm!

WHAT???  This is great!  A bit embarrassing  also.  The manual indicates a mini input jack socket in another location and I never once looked for anything else.  Thanks for the post/picture Tomtreas.  Looks like I have another good shelter in place project for today.
