Hi, only I wanted know what version you installed if exist another high, because I've same player with ver.2.07. Up version still doesn't exist. Last time I bought docking cradle and also I searching where I can purchase remote controller for this player. I know, it exist but is including for korean model. Speakers for YH-J70 also no exist, if you conect any speakers the volume is too low, the 3.5mm stereo jack is only for earphones or headphones but no for speakers, maybe set for PC who has amplifier.
Yours sincerely piacek
