Difficult to find. Use the Navigation screen,that is map, not the Multi-information display. Hit Menu,Navigation,Detailed Navigation settings. Then scroll right to the bottom to Speed Limit settings. This has all speed limit setting plus school zone.
Same Guy on ebay is also selling previous versions and also claiming the disc came out of a smashed car. Im stating the obvious that theyre all copies and he's printing labels but most of the poor folk buying them would think theyre originals. And its a good earn for him too, would cost him 50 cents for a blank disc, id say his profit is about 90% on each disc. And he's sold hundreds. I emailed asking him how he can offer a discount on multiple discs when he has only one but he didn't reply of course.
