I've done some digging around the forum and it appears that the 03LX470's didn't come with parking assist sensors. My LX doesn't have a backup camera. Everytime I put it in reverse, whether I'm close to something or not, my vehicle beeps very high pitched, indiscriminately-spaced, varying length tones, as if I'm about to run into something. I suppose its something I can just deal with, although it can be alarming, when I know there is nothing behind me and I am backing up and my vehicle is beeping at me. Anybody have an idea as to how I can either: 1) adjust the sensors so they actually work when they would be needed, or 2) remove the sensors altogether?
