I put a 32 Gb SD card in the SD port and it plays well, and the browse function works, too.
The issue is the number of songs the player thinks is on the card. There's ~1,700 actual songs on the card, but the screen is reporting ~4,800
It's not a big issue, but I wonder how to reorient the count back to actual.
It's amazing to me that I can take the SD card out, add more songs to the card from my home computer, reinsert the card days later, and it starts right back where it left off when I removed it even if other SD cards have been played in the meantime.
How it know?
