1. A mounting structure for a magnetic field sensor and a display means for use in a vehicle compass system comprising:
- a magnetic field sensor normally stationary with respect to a vehicle on which it is mounted for creating electrical signals in response to the position of said sensor in relation to the earth'"'"'s magnetic field;
a digital display means responsive to said electrical signals for displaying the vehicle heading in response to said electrical signals;
a mounting assembly for supporting said magnetic field sensor in a pivotally adjustable position with respect to a vehicle; and
means for pivoting the magnetic sensor secured to said mounting assembly to a predetermined adjusted position when said mounting assembly is attached to the vehicle, said means providing pivotal adjustment of said magnetic sensor independent of said display means whereby said mounting structure can be utilized in different vehicles by adjusting said position of said sensors independently of the position of said display means.
