A battery-powered wireless content loader for an entertainment system of a vehicle includes a multi-mode wireless data communications module with at least a first communications mode and a second communications mode. A controller establishes a data link to a remote content server with the multi-mode wireless data communications module to retrieve multimedia content from the remote content server. The controller selects either one or both of the communications modes based at least in part upon an evaluation of availability of an access point for the first communications mode within range. A data storage device stores the retrieved multimedia content. An electrical power storage supplies power in response to the vehicle being powered down. The controller copies the multimedia content stored on the data storage device to a content server of the entertainment system following the electrical system of the vehicle being powered up.
