How to add a stream to your My Streams folder on your Grace Digital radio
Sometimes you want to add a stream to your radio that doesn't necessarily need to be added to the database.
Your radio must be registered at myradios.gracedigital.com
To register you will need to do the following:
1) Get a fresh registration key from your radio-non+ models. (this key changes often, so you will need to enter it on the website right away) Go into your 'settings' menus and select 'register' and write down the key (code) that is provided
2) Go to myradios.gracedigital.com and enter in your registration key and create an account.
3) Then on the side of the web page you will see ‘My Stuff’/My Streams
Click “add stream” and add a name for the Stream that you will be adding.
You will need a non-flash url, without an embedded player for the stream, and the best way we’ve found is to ask the station. Some stations do list streams available for windows media player or realplayer Enter this in the Stream URL field. And click submit.
4) Go back to your radio and unplug it then plug it back in. Then turn it on. From the main menu, select My Stuff/ My Streams.
Registering your radio allows a few extra features. .
Step One: Go to www.myradiosplus.gracedigital.com and click ‘Registration’ to create an account
Step Two: In the menu on the left hand of the browser select ‘Radios’
