What is the name of that iPhone holder, and where did you get that iPhone holder?
From the various photos you have posted, it seems as if you were able to integrate your screen into the visual field of the dash very well, so as not to interrupt the driver's ability to scan horizontally for risks. Well done IMO.ProClip, you can get a mount specific to your vehicle, then a holder specific to your device.

I added the vertical extension plate to get it a little higher:
