Dave, don't you find the satnav a little out of the way for easy viewing? I just use the suction mount to stick mine to the windscreen, as low as possible.
I see you have a tax disc holder. I have the same one but can't wait for it to become obsolete in October, and that would be another spot to mount the satnav.
Your red tell tale for 70mph on the speedo makes the point that parallax is a big issue with an instrument so far off the drivers angle of view - it is at about the 65mph mark. To my mind the road speed is so important, that I would be very unhappy with the speedo in that position. I much prefer it straight ahead as in my 2005 4/4 (and presumably your roadster) which gives the best of both worlds as both speedo and tacho are in front of the driver and visible through the steering wheel. Interestingly my speedo is almost exactly accurate by GPS, unlike most cars that read 5-10% over.
