I know I'm coming in a little late here, but we just took ownership of a 3685RL and yes it has a GT2 in it. It does sound tinny and when I put a dvd in to see how it played, it played the disk in black and white, color was gone!!! Went into the menu and tried to change settings, menu disappeared and I can't get it back and it won't play movies any more... So, I can use it as a radio since it is already tied into all the speakers in the trailer... I went out today and bought and installed a Samsung sound bar with a wireless sub woofer and a Blu ray player... What a HUGE difference... I will have the GT 2 looked at when I take the trailer in for minor warranty work, but it definately will not be my primary movie player... My old Alfa came with a full 5.1 surround system tied into the TV... I really like the Bighorn so far, but when you spend the dollars these Heartland trailers cost, why are inferior stereo/ dvd players installed?
