We installed a K3 on my 2021 Goldwing, today. When both front and rear cameras are connected, Wi-Fi does not work. The light on the remote unit does not come on, and I can't detect it on my cell phone. However, when the rear camera is disconnected Wi-Fi connects, and I have an image on the front channel. The distributor is sending me a new rear camera and I hope that corrects the problem.
