Panda 100HP Topnavi head unit problem

[daiblack]

I have bought and fitted a Topnavi android head unit and to be fair it's been mostly plug and play except for the 2 connectors for the steering wheel control (picture attached) and having searched high and low I can't find where they link up to so any input would be most welcome. I'll get some pictures of the head unit later.
My Panda 100HP is a 2010 model.
