I have an 06 a6 4.2 sline. I simply removed the dvd from the player to see what ver it was. After I inserted it back into the dvd player the dam thing will not update the location. Under the details it says 0 sat. Does anyone have any ideas on what the issues could be? MMI seems to be working just fine it populates the map ect just with the wrong location it is off about 20 or so miles. Thank you for any help!
