Hi i have recently bought a 55 plate audi allroad fitted with the sat nav plus mmi system. When i tried to use the satnav today it was saying my current location was in a different location to what i actually was it was about 45 miles out can i reset the sat nav current location? Also the parking sensors are not working, when reverse gear is selected it does a long bleep then a short beep then goes off it lights up and flashes on the button next to the hand brake. Can this be fixed ? NEED HELP.
