No, it will only work with devices designed and programmed with appropriate firmware to handle them.
For example, the e200 series which will recognize and play regular SDHC cards will not play the SlotRadio cards. Even the Fuze in it’s original state, would not play these cards. The ability was added in a later firmware update.
The Clip+, being the latest & greatest player offering from SanDisk can handle these cards out of the box.
