For some reason I thought this function was tucked away in the service menu somewhere. I was pulling my hair out trying to find it as I attempted to get my new-to-me BV7 to play nice with an ATV.
I was about to raise hell with my dealer for not actually assigning the inputs/connections/PUCs etc. as I had asked and I thought they fudged it. Turns out they just did the minimum and only updated the PUC library and called it a day.
Thanks for posting this, Guy! I’m down to one remote, the greatest remote, my precious Beo4.
