I took ownership of an "18 LX 570 last week and plan to install my Kenwood TM-V71a radio this weekend. The plan is to mount the radio underneath the passenger seat, the remote speaker under the dash on drivers side and the control head in the wireless charging space beneath the stereo. I the head unit does fit in that space with some room around it so I would craft some mounting bracket to fit in that space. Any reason not to mount the control head in the wireless charging space? I would mount the antenna on the rear hatch via a "lip mount".
