Having bought 2 x 4GB SD memory cards, then got a reader which was compatable with their large size to format them, I am STILL having problems with them.
I now have one card which has about 10 albums in individual sub folders which works ( although car states that it is a 392 megabyte card).
However, the other card, I have formatted and added individual tracks (about 30 or so) and the RS4 does not recognise the card is there.
Any help gratefully received
