A good start

Though there are limitations I find the App more than adequate for the job. Bit finicky to setup but I think it was more my network issues not the App.
It handles the control of the system well and since I only have a Sirius subscription, I was pleased with the Internet access. Others may find having 5 options a bit wanting. There are tones of Internet radio stations to chose from.
Easy to use and more than handles all the tasks I ask of it.
I did not experience any of the difficulties other reviewers did. I recommend not only the Bose systems but their app is a winner in my books!
