AUX in on W13801 possible?

[Jiuz]

I'd like to add some kind of aux in on my W13801 factory stereo. Has anybody had any luck in achieving this?
Thanx

Maybe this? http://www.yarisworld.com/forums/showthread.php?t=56732
If the stereo has a 12-pin connector in the back I'd guess it has a good chance of working but cannot guarantee it.

Thank you for responding.
I'm sceptical if that would work on my W13801. It does have the 12 pin connector on the back, but it has no button for CD changer on the front. Judging by the pictures of the W58824 in that thread it does have that kind of buttons.
Also, if you take a look at this product (https://www.amazon.co.uk/Toyota-Yaris-interface-Adaptor-iPhone/dp/B00JEWSV8S) which I guess is similar to the one you're referring to, they say it's not compatible with the W13801 model.
I hope someone out there can confirm positive outcome with this particular model.
Any help appreciated.

I'm also looking for a solution for this model. Can anyone confirm if they've found a way to make it work?
