Can anyone tell me where the Navigation System GPS Antenna is located?

The workshop manual says, "The global positioning system (GPS) antenna is connected to the DVD reader by a co-axial cable, the inner conductor of which carries a 5 vdc power supply. The antenna is secured to the rear parcel shelf (coupe) or the convertible top stowage compartment by a self-adhesive coating on the base."

I have the convertible. I cannot see anything in the top stowage compartment, however, I did find a small, white, electrical connector in that location, left (driver) side.

Perhaps my antenna was removed by a previous owner.

Thanks in advance.
