I'm planning on updating the maps for a 2013 IS, but I have heard it is not possible to do it yourself, and you have to bring it to the dealership. If I have the techstream program set up on my computer, and I purchase the usb with an ACN from sewell, what else will I need to complete the map update? The 2013 IS has a generation 7 navigation system.
