It seems I never finished this topic.

As set up on the dash shelf.
Techgripper to the left with the twin power supply behind and to the left. The X-gripper to the right. There's also a GoPro cam mount but it's not used and the plan is to get the GoPro fitting for Tech mount as I only use the phone as a music player. The screen is ear marked for replacement.
Phone and Sat Nav. mounted on the shelf. Both mounts can be used vertical, horizontal or anywhere in between. The Sat Nav. has a 6 inch screen which is larger than the new TomTom rider which is a planned upgrade.
