My dashcam arrived yesterday, so I've had a bit more of a fiddle with it. It's the sort of thing that's supposed to clip over the mirror. Two problems - the Defender mirror is a but small for its jaws, and it tends to droop with the weight of the camera and vibration as you drive along. So I've bent the jaws so it grips better and have pulled the mirror off the ball on the mirror arm, and forced it back on with a bit of Blu tack in the socket. It's all nice and solid now. I had wondered whether it would be too shaky to give a good picture, but that'snot a problem, and I drove over some bouncy roads to test it. The colour balance is a bit weird and all the trees look like copper beeches. I don't mind because I like copper beeches, but maybe I'll look for something to adjust later.
