Hi all, I have had my Audi S3 2007-2008 for a week now (love the car!) but im a bit dissapointed with the Navigation Plus system. The CD-Changer doesnt seem to play mp3s, when inserting a disc, the MMI displays "Unreadable Format" I know this question has been asked numerous times, but each answer seems to be different. I currently have the following version on my Navigation Plus System S/W 0650 HW H74 Map 8P0919884_AA_EUW Would I be able to upgrade the firmeware of my device? would this resolve the above problems? and also give me 3D maps? what is the latest offical release version? Also, would upgrading the firmware break the communications to the DIS? or would it work normally?
