My Windsport 34F came with a j212. After 2 years of constant issues, I chose to ditch the Jensen completely and installed a Voyager 3 camera switch behind the radio. This removes the whole switching camera functionality from the radio so you can install any 2 din flat screen radio you want. As long as it has a single camera input, the camera switch alternates from side cams to reverse cam when you use the turn signals or switch into reverse. It's a bit of work to install but well worth it. Since it's Voyager, the camera plugs match the Jensen plug. I went with a Dual 2din radio with full blue tooth features. Big improvement.
