Hi @tratori ,

Is the volume of the BT music source as high as it can go?

If it is then you may have to consider this option as there doesn't appear to be any other way to control the volume.

If you decide to go with this, it is not a recommendation to use the supplier shown. It was just to give you an idea of the cost of a replacement remote control. There are other suppliers that may suit you better, Just search for Bose 10 sound dock remote control unit to get results
