No, the autopilot needs waypoint, XTE, SOG, etc. to run in track mode. That needs so come from a chartplotter/GPS combination. In my schematic, these sentences are transmitted by OpenCPN from the Netbook through Bluetooth to the autopilot. AIS has nothing to do with this. The AIS sentences go the other way through Bluetooth so that OpenCPN can plot the traffic.
