Software for embedded vehicle computers in a motor vehicle is updated using a smart phone having Bluetooth connectivity or USB connectivity. An application program or “app” running the phone queries a server via the Internet, for any available software updates for a vehicle. The vehicle is identified to the server by the app using the vehicle identification number (VIN). When an update for an embedded computer is available, the server transfers the update as one or more files, which are transmitted to the phone via a cell phone network and stored in the phone until the phone can be linked to the vehicle. After the phone and vehicle are linked the update is transferred to the vehicle, preferably using Bluetooth. Software on the vehicle copies the new software into an appropriate memory device via a bus running through-out the vehicle. |
