I really do not know. I ordered this card the same time as the sound unit. By the time I decided to try it, I realized that it is not the correct card to fit my machine. Not sure if I can still return it or not.
If you like waking up to the sound of natural sounds then this is the product you must get! Easy to program and love waking up to the sounds. Only downfall is getting the diffuser to work not sure how to get that part to work.
5 stars if there had been a radio as well, But living in So Cal where it never rains, I LOVE the rain feature. I LOVE the campfire feature, which I had never heard of before. There's a timer or all-night sleep therapy. Since I just moved on to a busy street, it's been great at helping mask the noise and allowing me to sleep through the night. It's a great investment.
