What is the v-aux for? - Yamaha HTR-5930 Receiver

Echo Dots can also be connected to your soundbar through an AUX (3.5mm) cable. This is because Dots are equipped with an AUX output port, and most soundbars have an AUX input. This is an easy, wired connection that is possible with a soundbar, as long as your soundbar and Dot are near one another (or you have a long AUX cable).
Here’s how to make your wired connection through an AUX cable:
Get a 3.5mm AUX cord. Make sure it is a good length
Open up your Amazon Alexa app on your smartphone
Select ‘Devices’ from the Main Menu Settings
Select your Dot by its name
Select ‘AUX Audio’, then ‘Line In or Line Out’
Connect your AUX cord to your Echo and your soundbar
Now you are connected through your AUX (3.5mm) cord, and any streaming or listening on your Echo Dot will come through your soundbar as long as both are powered on. If you ever want to listen to your Echo Dot through another device, simply disconnect the AUX cable from your soundbar.

You may. Have a broken or disconnected wire

You need an extra part to use the AUX function, part number CD-RB20 or CB-RD10. You then have to turn the function on in the settings:

1) Press FUNCTION to select AUX.
Press FUNCTION repeatedly until AUX appears
in the display.
2) Select AUX on or off with 5.
Pressing 5 will switch AUX between on and
off and that status will be displayed (e.g.,
AUX :ON).

1 press function repeatedly until you see aux on screen select aux .
2 press select aux on or off turn on aux
once you turned on aux fucntion when you need to use it use the source button to change radio to aux here is a link to its in german and english . http://pioneer.ipapercms.dk/Manuals/DEH_P6800MP_XRD7099_manual/

OK - had the same problem and got it finally figured out. Power the unit on the ignition key. Press and hold the source button so the unit shuts off. With the unit shut off press and hold the function button (the key is to hold the function button down) The clock, aux etc will show on the screen. Press (but do not hold) the function button and it will move to each function. When you get to the AUX press the ^ button and the will switch the AUX to "on". Once you know, like everything else, it's pretty easy.

try this
