brother i am in total disagreement of soldring wires when you can use a male end of cable as said by bulldog1993,
secondly aint that the stereo input/AUX port on right side of your channel button line in last pic, if it is just stick one end of male to male stereo cable there and other to the modulator.
third i am still not getting it, those audio video sorta things at back sides are outputs, or atleast in my kenwood case they are, can anybody confirm this those can inputs aswell or can be used as inputs.
lastly your unit doesnt seems to have any AUX port in back panel
