I've not seen one of those connectors before either, but if you are doing the same idea as me and putting a cubby box in where the old stereo was, then the cable length though be fine.
Whilst mine use the flat, thin ribbon cables, which are more annoying than a nice connector like you have.. there's enough space for me to disconnect/connect them in situ with just the cubby removed.
Your actual control box looks shorter than mine too (mine's full DIN depth) and to get mine in, I used a shallow cubby, rather than a deeper one. With the deeper one in place, I couldn't get the rest of the control box to sit nicely and all the associated wiring to fit easily!
Some other pictures of my install, which may/may not help you... You won't have the open case though - as I took the top off mine, and then cut the back plate down to size to fit...
The guts of my unit, again small control board in a big space - so much of it is empty, just to make it a 'double DIN' unit...
I found when loading mine up with things - DVR dash cam, DAB, 3G modem, Bluetooth, Nav app all running, it was getting pretty slow and a bit glitchy. I did all my testing on the bench too, and felt the heat sink for the processor, and it was almost untouchable, so decided to fit a cooling fan to it, and power it from the ignition switched 12V source. It now runs a LOT cooler and without issues. Looking at the specs of yours, it's a quad core, whereas this is an octa-core, at about 1.5ghz - so depending on what heatsinking they've put on the processor, you might be OK - but if it starts getting slow or glitching at all when it's been on and running for awhile, then adding a fan to the heatsink might help. My old one which was octa core was glitching at times on the GPS, but generally only when warm (it kept 'jumping' the location and the app kept 'recalculating route' which got annoying pretty quick!). As I'll probably be reusing the old version in one of my project P38's, I'll probably look at fitting a fan to it and see if it makes a difference.
This is where it gets more interesting... You can see where the unit is sitting on the cubby I've installed - which puts it pretty much behind the bottom of the screen when the fascia is in, and the front of the unit 'tucks' up on the lip of the dash aswell, so it's not rattling around!
This was my 'test fit' install to make sure it all screwed into place, worked etc - this is with the screen/SD card cables connected, and the unit tucked back up on the lip of the dash.
This one was actually taken, so I could reference the wifi reception of the unit from the house (it's got a RP-SMA connector for the 'stub' antenna they supply with it, and I've extended that and fitted a 5db antenna in one of the A pillars for 'better' reception - but even then it isn't that great, but I'm looking at either a 10db antenna or adding a small wifi hotspot at the end of the house where the car parks... though the 3G modem seems to work pretty well. But I digress, this also shows pretty well the cubby box removed, and the unit dropped down - you can see the screen (bigger) and GPS (smaller) ribbon cables. With yours, the mini IDC connector would be right there and able to be plugged in/out, so if you have to get the unit out, then you should be able to do so without removing the whole fascia!
Hope this helps, or is at least interesting
