Can anyone tell me how to select an area for navigation? I viewed the instructional video on the Lexus site last night and it indicated using the "Change" button. However, when I push change, nothing happens. Further, there doesn't appear to be a map area already selected, as the region is blank. There is a map disc from '06 (I think the version shows 6.1) in the DVD reader in the glove box. So, at this point I am at a total loss!
