I haven't bought a new remote in a while, so I'm not up to speed on the latest models. I love my MX-980. I've been using it for years, and it has been a real workhorse. It is my understanding that this remote is no longer being manufactured. What model replaced it? If I purchase one, will I have to start over from scratch with the programming, or can I dump my current MX-980 configuration into the new remote?
