A:AnswerThe button mapping for the Harmony 665 will change based on the application you in, such as your TV provider box or Netflix. Sometimes the home option will be a selection on the remote screen, and these buttons can be customized to always be a home button if you wish, using the MyHarmony desktop software on your computer.
A:AnswerThis remote should link with any device. It does work with my Roku. (LG Tv, JBL sound bar, Sony HD player) There is a learning curve because the buttons are not the same as the roku remote. I am still trying to find out what buttons to push. I still use the Roku remote sometimes.
If you follow the directions when you sync the remote, You can have the system go into your roku when you start and turn on your TV. Hope this helps.
A:AnswerYes if the proper codes for the device are used also if it doesn’t you can do a custom learn feature but you may want to contact Logitech harmony division for assistance
A:AnswerUnfortunately I do not know the answer to your specific question. What I do know is that I have found this remote very confusing to set up and use. (And I consider myself to be relatively tech savvy.) If you are looking at other remotes, I would consider them. Just my opinion.
A:AnswerI just hold the off button down until everything goes off. And if it gets a little cranky I change the batteries. Or just push the help button and it will usually fix it. Just make sure you point it at the TV until you get what you want.
