See the attached photo. What is this?

Think that is the sensor for the magnetic direction finder. You can read the compass heading on your Javalena monitor.
I am not certain, but I would guess a satellite ant for XM or Sirius maybe.
I have the magnetic compus on my 320, but do not recall seeing anything on roof like the pix.
The XM radio sounds good but could also consider for a cell booster re: similar to a Wilson Booster.
It is the compass head. At least on mine it is.
George, that looks like an older model GPS antenna I had for an old Garmin on my old boat.
Thanks everyone!
