All NAV or GPS systems have this problem. That is, they interpolate address numbers with areas or end-points such as streets. You can always enter your current position at your house as home to be the most accurate. On some other systems you can name this kind of an entry anything you want, such as "Home" with your correct address. Unfortuneately, with the Camry Nav, while you can list the name as "Home", the system will not let you change its address description. A design flaw, but not too big a deal.This does show the limitation of the maps when looking for specific addresses. They will be off at times.Jeff
