AVS200HD Smart Source HD Audio/Video switcher

I have this unit in my 5th wheel and need to replace it as my current unit died and I’m looking to find where I can get a replacement.

Bought this 5th wheel used and have to have this thing on to get TV, audio, & satellite to function. I can’t believe how everything is connected to this thing!! (it’ll take more than an electronics Geek to change it out).
