A vehicular communication device and method for communicating with a remote server. In various embodiments, the vehicular communication device receives a plurality of device packets from a vehicle device(s) via a vehicular communication network, including device packets having a first priority and device packets having a second priority. Processing circuitry of the vehicular communication device determines the respective priorities of the received device packets based upon the contents of the packets, and queues at least some of the received device packets (and/or informational packets derived therefrom) in accordance with the respective priorities. The queued packets are output to a remote server for processing. The vehicular communication device receives responsive content from the remote server, which may include safety content, a servicing notice and/or targeted commercial content.
