When it’s time to pick out your own parking sensor, you’ll notice a few different types are available: - Replacement Sensors If your car is already fitted with parking sensors, and one fails, you can replace it with a new component. Bear in mind that you may need to replace all of the old sensors with the new ones to ensure the system functions correctly. - Aftermarket Wired-in Kits If your car does not have a park assist system already installed, you’ll need to purchase a complete aftermarket kit. These kits usually include everything you need for installation, such as a control unit and wiring. You may need professional help to install one of these kits safely and neatly, since they must be wired into your car’s electrical circuits. - Aftermarket Wireless Kits These kits consist of a set of sensors, and an all-in-one control and display unit. The sensors transmit information wirelessly into the cab, removing the need for complicated wiring. However, this type of parking sensor may not be as accurate as their wired-in counterparts.
