Black antenna looking wires help, second gen

Installing a new stereo in my 2015 and after removing the factory radio I’m seeing two black wires which I’m unsure what they are. Can’t see where they’d even plug into the factory radio unless it’s in these two female receptors that look like they should take male harnesses. Previous owner definitely had an aftermarket radio in here before so wondering if things were changed. Any help hugely appreciated

 

Yeah those wires used to have plastic connectors on them. Previous owner (or install shop) broke off the connectors instead of using the appropriate adapter. One is for XM antenna and the other is GPS antenna

 

Okay that’s good to know, that’s why I was thinking but thanks for confirming.
