My mother-in-law has recently moved into a retirement home in Jersey and has lost the remote control for her "Wave Music System III". I can source one from Bose USA but they don't post outside of the States. I live in Spain and have spoken to a retailer about replacements (he's working on it). The product number is: 049427. I also have another number (343.178.4300).
Welcome to the community, thanks for reaching out.
Sorry to hear that you are unable to obtain a new Wave Music System III Remote. As you are located in Spain, you will need to discuss this with your local product support who can be contacted HERE. You'll require a WMS III remote control 😊
