Hi Nigel. Nice solution. I've thought about doing the same but never got around to it. Wondering: Is there a MagSafe mount that you could put into the wedge? That way the phone would simply go on/off with magnetic mount, and charge while driving without wires dangling. I just don't know of a magsafe mount with a bottom that could be screwed into the block and have adjustment for angles. Let me know if you know of one. I'd be interested in one of your mounts. maybe I could just clamp a magsafe mount into the jaws.
