Hi,
Yesterday (1st July 2008) I took delivery of my shiny new A4. It's a 2 litre diesel and first impressions were somewhat marred by the fact that so far the Concert stereo won't play SD cards.

I've tried three different cards, all 4GB in size. I've tried formatting the cards, I've tried loading them with mp3 and again with WMA. I've tried a full card and an almost empty card. I can play the cards back on the computer easily. I've tried licensed WMA and unlicensed mp3.

Every time I put a card into the Concert stereo it thinks for about 30 seconds and then displays 'unreadable'.

According to the manual, the Concert installed in the car is capable of reading cards up to 4GB in size. That's a bit strange because if it can read 4GB then it is reading FAT32 filesystems and one would expect it to read cards of up to 32GB.

Anyway, the problem is that my Concert stereo can't or won't read SD Cards. Does anyone out there have similar experience, or even a fix? Or perhaps is able to point out something I've missed?

Thanks - Skidders
