An other solution is to mount the antenna inside the car.
(on the passenger seat for ex.)

More seriously, when I mounted & tested my tuner, I remember that the diod (red light) on the tuner module was staying always on, either the tuner was activated or not. This could explain your antenna problem. maybe next version...
