Fast shipping! But only two buttons work in this very big remote for my Yamaha amplifier, controlling volume up and down. Better then nothing I guess, since mine isn't exactly the actual model mentioned .
In my yamaha RX-V550 power, standby, mute, volume, sleep, input source select buttons work well. but, the amp and sound effect buttons, including the crosshairs keys, do not work. I'm sorry that not all buttons work in my RX-V550.
