I bought this MP4 player on ebay:
4GB 1.8" 260K TFT USB MP3 MP4 FM Aluminum PLAYER NB4
Just got it in today and everything works, but as a lot of people say, the navigation sucks on it. Anything I can do to improve it and any mods that are a must to have? If anyoen else has this one and can comment I really would appreciate it.
