They are available in Bluetooth versions which connect to your phone or standard models that have readers that are connected to the socket.

One of the most common issues with i20s can be that the throttle position sensor (TPS) becomes defective. This sensor programming is used to determine the opening angle of the throttle valve. The information is then sent to a control unit, which aids in calculating the amount of fuel required. A damaged throttle sensor can cause abrupt acceleration, erratic RPM changes and reduced engine performance.

Another problem that is frequently found in the i20s is the malfunctioning transmission. The transmission is a complicated component with many gears that mesh together to transfer power from the engine to the wheels. The friction between the gears causes wear and tear, which can cause the transmission to fail. Symptoms of a faulty transmission include clunking or grinding noises and rapid acceleration that is jerky.

Spark plugs are an additional aspect to be concerned about for the i20. The problem with the plugs is that they can cause damage to engines by not delivering enough sparks to every cylinder. If unchecked a damaged spark plug can result in severe and costly engine damage.
