A:Answer All You have to do is hook the plate on back and you need to update maps and away you go. Real Simple, but need computer to download and plug into the computer. Very easy to enter the address and whatever options you want. I Love it, better then my car navigation. I haven't had the back up sensor hooked up yet. Not in a hurry to hook up either, it was like a freebie bundle. I am very pleased with it. Don't know which vehicle I would be driving with the back up sensor is why I haven't done anything. You will be pleased though, nice big size.
About driving, I drove in South Carolina and it was real accurate.
