>>1537359I know your pain OP. I had one of these a bit ago. It definitely works with 512GB cards. I used mine in it (just formatted to FAT or FAT32 or whatever it was, ton of cheap chinese players use that for some reason). If you rockbox it you lose bluetooth support but everything else gets much better. Cannot remember if search worked. For me, I ended up returning it bc I wanted side buttons and I found this device annoying to use. I got a sony walkman A55 instead, it works well but unfortunately navigation is all touch screen.
Post back if you find anything, I am looking for this too. Especially if it sounds great (I would have kept the H20 Pro except I despised the volume knob, impossible to use in your pocket).
