Perfect for what I need as long as it works moderately well, thanks!
The documentation is really unclear for this item it took me a bit of time to figure out
that it apparently also plays MP3s from an attached USB slot.
Further confusing is the SD support is "via USB" which I wondered if it meant
that you should attach a USB SD card reader or if they just hid a SD slot inside the
space shared by the hole for the USB port; I think it is the latter though that's just a guess!
Being able to turn any spare USB flash disc or SD card plus this into a usable MP3
streamer is awesome; it's cheap, and especially since in those cases everything is powered by the car's power.
If you used the line-in jack to play from an external player, the external player would be operating
on battery or whatever other connected power source it may have.
The UI buttons and display look pretty much unusable while driving, but that's ok, I'm sure a major way of using
this with SD / USB is just to hit "play" and leave it running in whatever order thing happen to play in without messing
with it too much except when stopped or via a passenger's help. (A review says the remote only works at very close range
so I'm not sure that's practical to use when driving either).
If it had a connector for a coaxial cable to go to the car's antenna I'm sure the FM signal would get out to the car
much better; I'm sure one could improvise something if one wanted / needed.
Maybe now I'll have to get that 8GB flash drive from newegg...
