That's an odd location so I'd say it's aftermarket. GM does use USB in the stereo but the USB plugs are wrapped in a physical connector that won't come apart.I bought it used - one owner. So, it's not standard to have this cable? I'm going to plug in my wife's MP3 into it and see if it charges it, that will tell me if it has power or not.
I have it in my signature. Currently though I am running a GS90C as my front facing camera and the G90 is now my rear facing camera.Live Trash,
I'm just curious, what kind of dash camera do you have?
