Ecaplen95 Posted October 26, 2023 Share Posted October 26, 2023 Hi all, New here but just wanted to advice. My MMI sat nav maps stopped working it is showing different errors each time about the "data medium". After doing some research I think the disk is damaged as it wont read it and makes a buzzing noise when trying to read it. I also cannot eject the disk as I know audi disabled the eject feature to stop people stealing them. I am looking to buy a new Data medium and basically want to ask will a 2023 SD card be compatible with my model or do I need to get the same disk as I have now? Its an Audi a4 Technik 2012 which I belive had MMI 3g? and will I need to take it to a garage to get the disk out for the SD card version to work? Thanks in advance for any help!

Steve Q Posted October 30, 2023 Share Posted October 30, 2023 It might be easier for you to replace it with a used one. That will need coding to the car though. Quote Link to comment Share on other sites More sharing options...
