You dont have to enter username/password.
Just select the internet radio option from the menu.
Depending on the firmware version:
In the next step you either have to choose between "Region" and "Genre" Choose Region and follow instruction below..
or you have to select a region (like Europe, Asia, Africa etc)
In the Region list you will also see "MyFavorites". Choose this option.
Then you will see a list of usernames.. select your username and you will see the stations that you have selected on this website.
Thats all.
btw I will soon clean up the list of usernames in MyFavorites so that only those users that have selected a Penbex device and who have selected private stations will be visible there.
