2008 Alitma Base Radio question

[keltymd]

i have an 08 Alitma with the base not bose radio . I need another Aux in, since I do not like having wires hanging out the front of my radio, i removed the radio to install a Parrot Bluetooth kit and noticed there are a total of four connectors on the back of the radio. The one, if the radio back is facign you, to the far right is the main connector and the one to the far left wound be the antena. What are the others for? would i be so lucky as to be able to get a harness to allow me to use one of those as an AUX in?

thank you in advance.
