17. A system for re-programming one or more modules at a vehicle, comprising:
-
a vehicle telematics unit that comprises a processor, a memory device, and an antenna for establishing a Wi-Fi hotspot; an infotainment head unit (IHU) located in the vehicle that comprises a processor, a memory device, and an antenna for communicating with Wi-Fi hotspots, wherein the IHU provides both infotainment and re-programming functions for itself or one or more vehicle system modules; a first bus operatively coupling the vehicle telematics unit and the IHU, wherein the first bus carries information alerting the IHU that software updates are available; and a second bus operatively coupling the IHU and one or more vehicle system modules, wherein the IHU re-programs the vehicle system modules via the second bus. - View Dependent Claims (18, 19)
