2014 Corolla with the factory radio 100149 adding XM

#1
I have a 2014 with the standard touchscreen Bluetooth radio. The part number is 86140-02050 model 100149. I was looking to add the factory XM module to it. The part number for it is 86180-0E011 and it was advertised to fit the 2014 and be plug and play. It has four plugs in the back, one is the antenna and apparently the other three are supposed to plug into the factory radio. The problem I found after the purchase is the factory head unit has only one open plus and it doesn't seem to match up to any of the XM unit's plugs. Has anyone figured this out or am I just SOL? I know the factory navigation unit has the extra three plugs for the XM unit, but I just wanted the XM. This is for my wife's care, so please no questions why I want crappy XM. I want it because she does. Maybe there's an adaptor cable or something. Thanks in advance.
