Thanks petaf! I had the same information of you... But mine come with my 2013 motorhome. I talked with a the technical support and they said to me that they are not selling parts anymore for this radio. So, if the problem doesn't need a part it's OK, but otherwise it's often not possible to repair it. I bought a new one, identical (JRV212T) at rvcams.com for 570$US. Tim, the owner is very nice and the price is good. I'm suppose to receive it in few days. Here's the link...
