I know this is going to fall on deaf ears, but it seems a few software changes in my '07 A4 S-line SE would be really useful;
1. Make the MODE button on my steering wheel actually do something useful (don't have a phone fitting), like switch between the radio and the CD player on my symphony radio/cd, instead of saying 'no function'
2. Make the MP3 filename font a more normal size, so it fits on the display rather than the 10 letters you get with the 50pt font, could even make it 2 lines
3. Make the Symphony CD changer show the CD disc titles rather than just whether its MP3 or (audio) CD content
4. Make the steering wheel scroll button rotate through the preset stations instead of randomly selected radio frequencies that happen to have RDS
Oh well, I can but hope!
