My 03 S also came with the Navigation but is clearly out dated, is there an update, cause the neighborhood I live in doesn't even appear?

Thanks

There are likely both updates to your software, as well as updated Nav discs.
You probably have the CD system, where the maps are broken out by region. Unfortunately they're not cheap, but sometimes used ones can be had on ebay.
