We have a 2015 Prowler P292 5'ver which came with a Furrion AM/FM/CD/DVD player.
It was replaced (upgraded to the next model) by our dealer as they took it out to work on the coax wiring behind it, and when it was reinstalled it was screwed in so tight that when it needed to be pulled again they had to destroy it to get it out of the entertainment center (also damaged the woodwork in the entertainment cabinet).
However, I bought a Sony BluRay player (which also has internet access) that sits on the entertainment center, so I never plan to use the built-in stereo for playing discs, but for sound only.
Did the same thing in our previous Heartland TT.
