Hi, I am looking at an older MP3 by Rio (s35) that has 128MB on board, but allows for expansion using SD Memory Cards. I have seen people say that you can expand it to 256MB using SD and other's saying you can expand to 640MB.
My question is the expansion limit a factor of what SD Memory cards are available (now 1GB is available) or is there something in the electronics?
I've done it before and didn't have problems, But the songs are put in by using a memory card reader direct from the pc. I couldn't manage the songs by using the Rio.
