SEAT_HEADREST_HEIGHT_POS

What it is

(Deprecated) Headrest height position

This property is deprecated because it is defined as type VehicleArea:GLOBAL, which means all seats use the same value. Use SEAT_HEADREST_HEIGHT_POS_V2 instead which fixes this issue by being defined as type VehicleArea:SEAT.

Sets the headrest height. Max value indicates tallest setting. Min value indicates shortest setting.

This property is defined as VehiclePropertyAccess.READ_WRITE, but OEMs have the option to implement it as VehiclePropertyAccess.READ only.

How the ID is built

A property ID is a 32-bit value packing four fields. Reading 0x11400b95 apart:

Field	Mask	Value	Means
Group	0xf0000000	0x10000000	SYSTEM
Area	0x0f000000	0x01000000	GLOBAL
Type	0x00ff0000	0x00400000	INT32
Ordinal	0x0000ffff	0x00000b95	0xb95

Reading it from an app

CarPropertyManager mgr = (CarPropertyManager)
        car.getCarManager(Car.PROPERTY_SERVICE);

int value =
        mgr.getIntProperty(VehiclePropertyIds.SEAT_HEADREST_HEIGHT_POS, 0);

This property can be read and written, though an OEM may implement it as read-only. It fires a callback whenever the value changes.
