Do ELECTRONIC flight computers have isogonic line values factored into them? If so, how does it know where I am departing from, etc?

Elctronic E6B's, such as the CX-2, are useful in calculating a number of functions; one of which is true heading.
However, I never "tell" the electronic E6B the location of my departure OR my destination. Therefore, HOW can it calculate true heading without knowing which isogonic line to factor in?
It DOES calculate true heading...I'm just not sure how it "knows" where I am in order to calculate the magnetic variation factor required for my true heading.
