Nokia Lumia 625 - Why don't I have the LiveSight option available in HERE Maps, HERE Drive or HERE Transit on my Lumia 520, 521, 525, 526 or 625?

The LiveSight feature in HERE map views is not available on Lumia 520, 521, 525, 526 or 625 because these phones don't have a magnetometer (compass). LiveSight works only on phones that have a compass.
