with kgd online updates, it always updates to the same version, which is a bug. with 2.3 version, there is online update option, but u need to have sd inserted, i think it saves the previous firmware to it, or could download new firmware to it. i am not sure why it requires sd for update.
any one had installed 2.3 and checked the L/R audio outputs??
p.s. is there a way to check the version of the device? at the back i have a sticker : m3v2240000512. does it mean its version 2.2 with 512 mb???
