Systems and methods for communicating data from off-vehicle data sources to a vehicle are provided. In one embodiment, a method for obtaining data for a vehicle comprises: initiating an information request from on-board a vehicle; formatting the information request onboard the vehicle into a data file format to generate a request file; performing a wireless file transfer of the request file from the vehicle to a data center, wherein the request file is transferred to a file system location; polling the file system location for creation of a response file corresponding to the request file; when the response file is detected within the file system location, retrieving the response file from the data center to the vehicle; and displaying at the vehicle information responsive to the information request from the response file. In some embodiments, the file system location is a file system location uniquely associated with the vehicle.
