Try the RCA website, there's new firmware for that available for free under the button marked downloads. It'll reformat the player completely, and that should give it a kick I think.
I can't get the external memory card to work. It is a Lexar 256mb sd. I formated it FAT still says not enough memory . any help thanks I know this is not a good high $$ unit but I use it while riding motorcycles "dirt bikes " and the chance of lading on it or losing it it big so I use the rca lyra. Thanks
