2012(12) XC60: can reversing rear-parking camera be fitted?

[Matty88]

Hi Guys

i have only just signed up to the forum,i am after abit of help on my xc60..

I have had my head unit out as i am wanting to install a rear reverse camera

i have a few connections that are there but nothing in them,so would like to know what they are for...i have also found one at the side of drivers seat below the gearstick and a big grey one in the back below where the light is..
i am hoping some are for a plug and play camera

i had to buy the Led light for cupholders and both front door lights i did it myself easy,but i find it crazy all connection's are there but nothing in them...Volvo should of done it when making the car...

i have pictures of what i am talking about if anyone can help me with what they are for...

its not letting me load up my pictures for some reason,the connections on back of radio are grey/brown below geartsick is green


Many thanks


Matty
