When you say "auxiliary" input, by this do you mean a constant live feed?
You may have to tap into the ignition feed, or perhaps run a fused wire from the battery +
The radio system in the Doblo is mad! I fitted a JVC and if I switched the red/yellow wire it stayed on all the time. As it was, I left them as they were so it retains the memory when the ignition is switched off.
I am trying to do the same thing exactly - I have connected a yellow 6 pin ISO to 3.5mm connector. I did not get the AUX option when I pressed the Media button. There is another thread on here that suggested connecting the D IN and D OUT pins on another Delphi stereo with identical pin specification. That did let me select AUX when pressing the Media button- but still no sound . Did you make any progress?

Hi I had the same problem with fitting Aux cable to stereo, purchased a yellow connector aux cable from eBay to click into the aux socket on the stereo (advised it would work from ebay seller) connected but did not work! After some digging I found the same stereo where someone had cracked it... so as fitted to mine, get an aux cable 1.5 meter ish, keep the 3.5 mm aux connector, on the other end strip the ends of the three wires, you will need small female push connectors to punch onto the male connectors in this order:
Black to AFR
Red to AF earth (upside down T)
Light Blue to AFL
Next get a wire 2” long, add male connector to either end and connect to “D out” & “D in”, to complete the circuit, if you do not do this step the stereo will not know there is a connection.
That’s is! Once complete press media to cycle from CD to AUX, AUX will now be displayed.
Colours may differ on AUX cables but the black and red are the key colours.
Edit: Next get a wire 2” long, add female connector to either end and connect to “D out” & “D in”, to complete the circuit, if you do not do this step the stereo will not know there is a connection.
