In one aspect, the invention is directed to a parking assist system for a vehicle, wherein the parking assist system has two modes of operation. In a first mode a first overlay is added to an image of a rearward field of view displayed to the vehicle driver. The first overlay includes a representation of a target parking position. In a second mode a second overlay is added to the field of view displayed to the vehicle driver. The second overlay includes a representation of a projected path for the vehicle based on a current vehicle steering angle, and a representation of a target path segment for the vehicle.
