Time to chime in my 2 cents. No disrespect to you, as I'm sure the craftsmanship is top notch. I think the biggest flaw, and your design is flawed, is the bezel around iPad mini. It is too freaking big. Makes it look like it belongs/came out of that horrible GM dashboard in that second vehicle. You have the bezel on the iPad itself showing, then that second bezel, with finally the pod itself, it just looks too busy.
Also, the roundness of the corners don't flow well with the rest of the center dash piece. Sure, the CCU bezel is rounded at the edges but it's also "slim".
Lastly, the angle at which you mounted the iPad doesn't flow either. I understand where you are going with this one trying to reduce glare. The dash slopes at a 45 degree angle, give or take. Even the gauge cluster pod flows at about the same angle in the opposite direction. Your pod sticks out almost vertically.
My suggestions:
1. Make the bezel THIN, as thin as possible.
2. Make the bezel corners less rounded.
3. Make a "duck bill" kind of like the gauge cluster and have it look more like the OEM Nav Pod.
Or you could work a floating mount and go bezel-less like what the guys at Soundman Car Audio have been doing. Of course, that only works wirelessly and there is no charging the iPad while in place, but the iPad does have a long battery life, so that could be a non-issue.
Soundman also has a new iPad mount that is a combination of a side-slide mount and the floating mount that allows connectivity/charging while mounted.
Thin bezel or bezel-less would allow you to have a smaller pod overall, and aesthetically look better.
Also going this route would maybe allow you to mount the iPad mini lower on the dashboard. I did a quick photochop. Of course you would still need to implement a "hood" or "bill to reduce glare.
I'm not a fabricator, just throwing out some ideas out there. I'm sure you have the knowledge and capability to see this through.
I'm a huge Apple fan, and would love to see an iPad mounted properly on the NSX.
