not sure how they all work. I know the Harmony universal you program thru an online link , then with some info added it programs itself (while connected to the PC of course).
You can get different versions of that Harmony starting at about 15 bux and up past 100 bux.
I would not go for an expensive one, with not knowing if a universal remote will work or not.
The Harmony may not even be a good choice, as you pic from a list what you are tryin to control. The avov may not be on that list. It may just be okay to list it generically thou, like Android for instance. I am just not sure about that.
But there it is
check your messages.
I have a couple extra avov remotes. I will send you one, no charge.
