Kuda mount installed, and radio head attached.
When it cools down a bit outside, probably in a few days!, I will take the time to route the flat cable to the head under the Kuda mount, along edge of the dash and windscreen and down to the radio head under the seat.
The radio head could mount a bit higher, but I decided to start it a bit lower and see how that works, as the mounting hole(s) won't show if I then move it higher, unlike starting higher and moving down.
