How does the "electronic compass" work?

I know that the determination of the north direction in the normal Edge 1030 is done by GPS and forward movement.
But how can the 1030 PLUS determine the north direction even when standing still? It is not a magnetic compass, but an "electronic" compass. Can anyone enlighten me?
Thank you!

Beeing "electronic" doesn't prevent it from sensing the magnetic field. It's a Sensor based on MEMS technology.

Whats the bennefit?

Better handling of the routing position?

When you are stopped and rotate the GPS unit around the maps will shift to show the proper orientation. Much better than the 1030 which did not have this compass and the maps would freeze in whatever orientation you had been travelling before stopping which can make it hard to figure out which direction to go when starting again.

I think I sow this also at Edge 830, I don t know if the 530 has it

But yes, I undesrtand now, with 1030 is difficult to guess in what dirrection you have to go, specially when you stop
