I was playing around with things and testing bringing in some custom Network Datasets, Basemaps, and locators into an MMPK to be consumed by Navigator. Navigator didn't seem to honor the Basemaps symbology scaling for one, but the main thing I had issue with was locators built using Create Locator do not appear to be supported. What is supported are locators built using the soon to be deprecated Create Address Locator. Anyone know if it is planned to support Create Locator via Navigator in the near future?
