Abstract
A method for providing and utilizing navigation data can include identifying a grid that includes a plurality of geographical regions. Each geographical region can have an associated navigation data set which includes street level mapping data. Linking references for each geographical region can be defined. Geographical navigation bundles can be identified that conform to an OSGi compliant framework. Each bundle can correspond to one of the geographical regions and can include a navigation data set and a manifest file. The manifest file can include a version, date, and the linking references. A GPS equipped device can dynamically install and activate the geographical navigation bundles. The GPS equipped device can perform at least one navigation process based upon the navigation data set. The GPS device can predict when new navigation data is needed and can automatically acquire suitable geographical navigation bundles in response to these predictions.
