2014 Legacy type B audio, manual says "A USB memory that is connected to the memory card reader or multi card reader cannot be operated." But Aluratek AUCR202F with 8GB SDHC cards works great. Makes a nice installation, too, with the body of the card reader installed (Velcro) above the USB outlet. The manual also says this system has a limit of 2500 files maximum. Can anyone confirm or correct that?
