Abstract
A navigation method and system are disclosed whereby users of the systems are provided with backup driving instructions. A wireless communications system allows end users' computing devices to receive dynamic route guidance from a remotely located navigation services provider. The dynamic route guidance provides each end user with maneuvering instructions at appropriate locations along a route to a desired destination. In addition to the dynamic route guidance, the navigation service provider also provides the end users with backup driving instruction data. The backup driving instruction data can be used by an end user's computing device to provide backup driving instructions for traveling to the destination. The backup driving instruction data can be used in case wireless communications is interrupted.
