So I'm downloading both the latest 2.126 and Grace Notes 4118 from Sox's server. My questions are this:
On the server, only ISO files were available for both and I want to put them on USB as I don't have a disc drive. Second, I'm doing this on a Mac so does that change how I need to put the files on the stick. And finally, what's the process for updating Grace Notes versus the RHR software as a whole.
So I am going to answer one of my own questions. When I opened the ISO file on my Mac, it expanded the file into Becker and two CDI files mentioned here:
What version of Application Software did your RHR 730N come with?
