I have a 2006 Civic with the navagation package and also live in Los
Angeles. I have used it throughout the west and as far east as Ohio.
I have found very few missing streets. Some "new" streets aren't
shown, also some new extentions of old streets, such as Golden Valley
west of the 14 and Carl Boyer, both in the Santa Clarita area. Also
Golden Valley offramp on the 14 isn't shown.A problem I have found is
that its database of stores is very poor and lacks many retail stores
that have been around for years.
