Hello all. I have a 2014 Town and Country with a 430 RBZ radio. The other day I had my phone charging on the radios USB port. When I disconnected the phone my husband heard a pop and then the radio completely shut down. I checked the fuse under the hood and it was fine but I replaced it anyway. It still isn’t work. Any idea what the problem could be? I’m pretty handing so I have removed the radio from the van.
