Aux button on '09 Kia Picanto...no plug!

[Spare tyre]

theres not an USB socket anywhere is there?

Ive driven a kia with an aux button which can use a USB stick to play music, or the aux 3.5mm plug

This can be done. Took me days of research and experiment, but on my daughter’s 2010 Picanto, it was as follows:

You’ll need a mini ISO plug similar to this one. https://m.banggood.com/3_5MM-USB-Plug-Audio-Adapte...

I didn’t find any already wired correctly, so my best advice is to get this one or similar from eBay, and put the pins in the right place yourself.

For the aux in, you are going to use the middle block of 6 pins. As you look at the from the back of the radio, top 2 are audio L & R, and of the middle 2, the left hand pin is the audio earth. You will also need to jump a short between the middle right hand pin and the bottom left pin. This switches on the aux option on the radio. That middle right pin is labelled “Aux input detect” on some of the wiring diagrams I looked at, but none of them gave me any idea what to connect it to. I found out what worked through trial & error.

Here is the closest wiring diagram I could find to what worked for a 2010 Picanto.

The relevant pins are on connector C, 3,4,10,11 and 16

Just out of interest, I think the usb pinout on this diagram are correct, but couldn’t get it to talk to my iPhone. It said it was trying to read an iPod, so maybe there were some firmware issues or something.

Your're a bit late to this party, like 5 years!

This helped massively! Parts ordered, gonna attempt this weekend. What would happen if I don't put a pin in the 'Aux input detect' socket? Can you clarify "jump a short between the middle right hand pin and the bottom left pin"... do you mean just connect a wire between those pins/sockets?
