Aux has disappeared from src options on kenwood car stereo

According to the manual, the aux input for the mpv622 is an optional accessory. If it's installed, you select the aux input by pressing the [SRC] button. Select the AUX/AUX1 display. Then press the [DISP] button for two seconds. The selected input blinks. Press the ? or ? to change the input setting.

press the src "source" button untill it comes up aux mode, you may have to go into another settings menu to activate the auxiliary inputs on the headunit

Here's what they don't tell you: AUX isn't automatically an option when you scroll through the SRC button. You have to turn it on. I know, I know...stupid. I had to contact Kenwood (the maker of the unit) directly to get an answer.

• First, press the SRC button repeatedly until it displays STANDBY.
• Then hold down the Menu button until MENU is displayed.
• Next press up or down on the right control knob, to scroll up or down, until AUX OFF is displayed.
• Next hold the right control knob to the left or right until Aux switches on.
• Now just press the Menu button to exit.
• AUX will now be an option when you scroll through the SRC button

Its becuase the aux is turned off as default so you have to activate it.
Put the unit into standby mode
Press menu for at least a second untill menu appears and then select the aux option and edit it to either aux on1 or aux on2 or aux off.

In order to access the AUX option the stereo needs to be in Standby mode. To do this just hit the SRC or source button until you reach the Standby option. Now hit the menu button and scroll up or down until you reach the AUX on/off option and just turn it on. Hope you find this helpful.

Try putting the unit in standby via the "SRC" button FIRST..., then press the menu button and cycle through to the "AUX 1" option and activate this....then press menu button again. When the unit is next switched on, you should have an "AUX" option accessible via the "SRC" button which will cycle through all of the availale modes ....standby-tuner-cd-aux etc etc.

with the unit in standby, press the menu key, use the joystick control to choose aux, and set the aux option to "on"...then press menu again to save...when you next switch on the unit, using the SRC button you can cycle through the available options...cd - tuner - aux..etc etc
