After I recently updated from 110 to the 120 upgrade. It went smoothly and everything seems to be working nicer. However, this has happened to me twice. While I was in the SD for my source I was browsing through my SD card for music and browsing back to artist/album, it'd automatically restart the system.

 

What's my issue? Too many sub-folders perhaps? IDK, but I'd appreciate your help, thank you.

Possibly too many files or folders. The Z120 manual says max 300 folders, 2500 files. Also max capacity SD is 16GB. I image some brands of cards may have issues too.

Not sure what happens when some internal memory/storage space limit is reached. Probably nothing good.
