Hello, I purchased a brand new in the box 2010 RNS-E and installed it into my 2012 A3. The person doing to vagcom say it will not take any of the coding. The navigation never asked me for a security code I am assuming because it was unused and mated with my car. What I don't know is why it will not take the code, and I am thinking it is because of the security code even though it did not ask for it? Any help would be appreciated. I am sitting at the shop now and have been here for 5 hours!
