Funny thing about the sound system in ours....the in dash Jensen is just fine for driving and we have a nav system to share between vehicle already. As for the coach/living quarters, the previous owners upgraded that. They upgraded the front TV to a LCD flat screen and added a LCD flat screen with built in DVD player in the bedroom. The front one is connected to a DVD/CD/Tuner (RCA) with a surround system and nicely hidden sub woofer. We tried it on an FM station to test and WOW what a room filling sound...and clean!
