I just got a C-MAX Energi and did a trial install of my Yaesu FT857. I previously has a 2010 Fusion Hybrid and the noise on HF from the electrical system made it unusable. However my trial install showed NO perceptible noise either running in hybrid mode or pure EV on either HF of VHF! This is great news. They must have fixed something. I order a mount for the control head from Proclip. It worked quite well in the Fusion. There are two version for the C-Max on their website. I chose the one that mounts just to the right of the steering wheel. You will have to drill a few holes in it to mount the control head, but it works much better than the goose neck type. I would like to mount the radio under the shelf in the back. The Energi has a flip up shelf made from composite that is wide enough to mount the radio to the bottom if I can figure a way to fasten it without butchering the carpet. Also, the manual say not to connect to the ground side of the battery. So I assume I can connect to the Positive side. There is a large black wire from the negative terminal the chassis. I don't see why I can't connect to the Chassis end of the wire or some other chassis ground in the rear. N8JJ
