I have the L05.00.04 firmware and i have to use CPS RT72 Version 1.00.02 to make it work. Problem is that L05.00.04 firmware doesn't have the recording function enabled. i have enabled it into CPS but the recording function is still not present into the menu radio. This need to be fixed with a firmware update. Where can i download new firmware L05.00.05 or L05.00.06 or more ?
