    weather proof it with Plasti-Dip and mount it outside the vehicle.

    This cannot be stressed enough, the band that GPS operate on is very sensitive, you need to have a ground plane and have clear unobstructed view of the sky. This means mounting the antenna outside the vehicle, on steel.

    The heated windshield in my vehicle completely obliterates any GPS signal, also the trouble with windshield mounting is that you only have a limited view of the sky. Im lucky, my hood/bonnet is fiberglass, so I have mine mounted on the battery cage (steel) which protects it from the elements and allows great lock.

    I have the same kind of heated windscreen which also blocks GPS coz of it's metal coating.

    When I had the GPS on the roof 6-10 sats. When I mounted it on the left side of the dashboard 2-3 sats. When I mounted on the right side 6-10!!

    Weird !!!

    Not wierd, the wires in the windshield act like a polarizer, so just like the sunglasses, the attenuation varies with the angle presented to the sky.

    Ideally yes but not necessarily true...

    It worked well for many poeple without having to install it outside the car. It just all depend what sort of material is in front of the GPS receiver.

    Isnt the heater wires too wide apart for the signal to be affected?

    Mine in the front are not more than 1/2 cm apart and def. affect the signal.

    Lots of GPS devices are made to sit inside the car - For example the new generation of speed camera detectors which use GPS to find the location.

    Isn't the thing magnetic? You can stick it to the upper part of the hood at the top of the window.

    Mine was magnetic; I can even stick it where the passenger door window meets the metal frame (inside of course).
