For what it is worth, I have a Lockpick in my Chevy pickup truck. I have had it for almost 2 years now, and have had no problems. It does what it says it will do: automatically switches the Nav screen to the camera when in reverse, allows you to integrate an IPOD into the sound system, allows you to input navigation destinations while in motion, etc. On the Chevy, you control the Lockpick with the stereo buttons on the steering wheel, I don't know how the Fiesta version is controlled though. You can connect any standard camera to it, there is a 12 volt power output for the camera and a standard video input connector. You do need to run a long set of wires to the camera from the dash, but many of the cameras you can buy come with those cables.
