We use an ESRI provided StreetMap Premium with custom roads Pro project to create multiple mobile map packages used in Navigator across the US. We have different travel modes established in our network dataset, but the default travel mode changes depending on the location of the map package.
Mobile map packages inherit the default travel mode from the network dataset, which becomes the default travel mode in Navigator. It would be convenient to have the option to specify default travel mode in the "Create Mobile Map Package GP" tool so it does not always have to be the network dataset's default travel mode. Currently the work around is to change the default travel mode on the network dataset before generating each MMPK.
