Hey guys, I am going to be installing a AVINUSA unit soon and it has the input the gps antenna, The unit comes with a gps antenna but i would rather use the factory antenna already in my car, less wires and less mess,

where does the 2013 F30 factory gps wire run to? I have a CIC head unit, does the wire run into the trunk com box or to the back of the radio?

thanks !
