I am considering a Passport 9500xi for the XLR. I have a Valintine for the Vette and like it. What has got my attention with this detector is it has GPS and will tell you whats on the other side of a hill or around a curve. It also will identify all cameras both red light an mobile radar. I am wondering about the box mounted at the top of your windshield that I believe contains the Sat radio antenna and the GPS navigation antenna. Does anyone know if this radar detector will work with a windshield mount with these other two antennas already in place.
