We are having trouble with our DV3200 as well. I have no radio signal now. It just quit working one day. I checked the antenna connection at the back of the unit and it is firmly in place. Perhaps the antenna wire is disconnected from the external antenna. That is a bit more challenging to troubleshoot. I plan to hook up a separate antenna to test before disassembling the antenna on the roof.
Also, occasionally the unit will just freeze up. Only after hitting the reset button once or twice will it begin to cooperate again - without the radio, though.
I put a call in to Furrion today. We'll see how quickly they respond with a solution. I will update when I get a response from Furrion.
