Well I just went to the Audi dealership to try to use an '09 disk to update and they were really obnoxious about helping me. The service guy said he couldnt because he would be held responsible for any damage as if an official update would cause any harm. The sales manager was going to charge me for the new disk and when i mentioned I was under warranty they said that their warranty doesnt cover software. In order to do this legally one must buy the new dvd for over $100 which defeats the purpose entirely.
