Question on headunit t1818

[holaplaneta]

morning fellas, just looking for some info on install of a headunit after searching for days, i got this headunit toyota part PT546-00121 as a gift recently from a friend who upgraded to the navigation unit, i got a 06 tc and i didn't get any of the harnesses, i was wondering if anyone knows after getting the 3 harnesses needed will i retain function on my Steering wheel controls? ipod control? and i dont care much for the bluetooth as its not that important at the moment. anyways thanks for all the help.
