Forerunner 955 SDK min version

Hi all,

I would like to build an app related to music. I have currently a forerunner 955.

I've downloaded the SDK manager.

When i create a project i select the latest SDK but no products are available.

If i select the oldest SDK the forunner are not present.

I selected as well "audio content provider" as type.

I don't get where i'm missing the info.

Thanks for your help
