We have the Furrion stereo in our 2015 Prowler P292 . . . have not used it to play any DVD's as we have a BluRay player to use for watching movies.
We haven't had any issues with the sound, but the radio reception is pretty bad.
I had tried to get into the cabinet to check the antenna as I thought it was probably the same as our previous Heartland Trail Runner (the balled up diapole wrapped up in a ball with a rubber band around it stuffed into the wall), but there was no way to get into that cabinet.
While on our last camp out (in the mountains near Gunnison, CO) I decided to take the stereo out of the cabinet . . . what a PITA that was!
I was pulling in all kinds of radio stations in the truck, but barely pulled in one station in the trailer.
But to my amazement, the antenna was connected to the roof antenna, yet still not getting good reception!
I tried with both the antenna amplifier on and off.
I also discovered on this trip that the cable TV receptical on the outside of the trailer doesn't work, so maybe this has something to do with this.
I may just go to Car Toys and get a good stereo to replace the Furrion.
