I just tested it by riding round the block. The interface and position is all good. I need to work out what apps I want where but for simple sat nav it was good. MRA wasn’t setup and I need to try that.
Yellow remote control cable has been heat shrinked and once the mounting is finished I will tuck it away.
My concern about the mounting position is still there, it wobbles, not much but enough to be annoying and know it will eventually break. As I have failed to find the correct adapter plate, I think next step is to sketch it up, get it modelled at work then find someone locally to 3d print it.
Unless anyone has a better solution?
