Had occassion yesterday to plug a memory stick into the USB input on my Marantz 603. It came up as 'Unsupported'. Not too bothered I tried another stick with the same result. Now tried all the sticks I have with exactly same result, and I know for definate that some of them were working OK previously but not now.(probably been over a year since I last used this input}. Checked the 603 firmware which confirms it is the latest, also checked the sticks to confirm they are formatted to FAT32. Run out of ideas for now, anyone got a suggestion? Have asked Marantz Support but no response as yet.
