I am installing an xm receiver. It requires that I locate the site of the FM antenna. Does anyone know here it is located? Thanks

It is embeded in the rear window glass, with an amplifier in the tailgate. If you ar installing an FM modulator that connects to the antenna cable, the connection is on the back of the head unit, but you will need 2 adapters for the euro style antenna jacks to US style on the XM FM modulator.
