IN-car navigation is more accessible than ever.

From the increase of sat-nav as a standard feature, to smart phone mirroring, excuses for getting lost in a car have been harder and harder to come by since the mid-00s.

However, the first in car navigation system debuted 36 years ago in 1981 as a dealer-fit option on select Hondas sold in Japan.

Called the Electro Gyro-Cator, it worked by using a helium gas gyroscope to estimate speed and the direciton of travel instead of info relayed by satelites like modern units.

The gyro could detect rotation and movement, and was linked to a servo attached to the transmission to help determine speed.

The Gyro-Cator was an adaption of technology used in fighter jets at the time, and the driver would have to place a transparent map inside the unit at the start of each trip.

The system cost 300,000 (A$3577, or around $10,000 adjusted for inflation), but was discontinued yes, really a year later in 1982.
