Fabia Monte Carlo 2013 steering wheel controls

Hi,

I’m interested in getting steering wheel controls for my fabia, however not really sure where to start? I know the head unit installed has a 3.5mm jack labelled ‘remote’ on the back, would this be where the controls would plug into?
 

I wouldn’t feel comfortable doing it myself so does anyone know of any garages that would do this near Middlesbrough area?? or is it even possible to retrofit on this wheel?

I saw there is a sort of stick on wireless option on eBay, but wanted more of a permanent solution
 

Cheers
