To each his own, but I bought the option for a GPS/Rearview camera/AM/FM/Sirius-XM/CD receiver and felt I'd made a mistake. The first problem was the position of the unit. For the most part, depending on lighting conditions, I could see mostly reflections from inside the RV. I like the review camera on all the time to help with lane changes after passing when towing. I also like the GPS to be in a position that doesn't require taking my eyes off the road any more than necessary. Unless you have someone to operate it for you, switching between functions can be a dangerous distraction with a touch screen and the sometimes small buttons. Anyway, I installed a separate screen for the rearview camera, mounted a standalone GPS (which I can easily take in the house for preprogramming) where a rearview mirror would normally be and just use the receiver for Sirius-XM. Still, the receiver has decent sound quality and after adding a subwoofer I'm fairly well satisfied. Doing it over, a good receiver without the added functions would have saved me some money.
