A vehicle computer system (VCS) configured to communicate with a mobile device, comprising a wireless transceiver configured to communicate with the mobile device. The VCS also includes a VCS software stack configured to interact with a mobile device software stack and a processor configured to receive a message from the mobile device indicating a version of the mobile device software stack. The processor is also configured to determine if the VCS needs an update to the VCS software stack based at least upon the version of the mobile device software stack, download an update to the VCS software stack from an off-board server, update the VCS to include the updated VCS software stack, and communicate with the mobile device utilizing the updated VCS software stack.
