[Android Head-Units] ZexGX:
Link to the one I bought: http://www.aliexpress.com/snapshot/6222933282.html

The front of the unit is indeed larger than the body of the unit, so I will probably need to make a custom bezel. It may not be a problem at all for my use.

I have had the unit now for a couple of days and it's working good in bench testing. It came with the latest software version (2.7.38? 2.7.39? I'll check again when I get home). I don't yet have the files to restore it from the seller or to compare that to the release already in the wild, so I'm a bit hesitant to try a full wipe to get root access. Overall it works good, but permanent root access would be great. So far I was able to use Baidu 2.4.6 Chinese to temp root it to get XPosed installed, then I installed some modules to customize the notification bar, and Holo colors like background, dividers, and selection color. I'd like to keep the stock launcher buttons at the bottom but change their appearance (they look like iOS themed icons), but I'm not sure how to go about that (don't know where the image files are or how to change them). Google Now Launcher did not want to work, as it claimed the default was set, but I could not un-set the stock launcher as default for Google Now to work (defaults section grayed out, even tried using a Home Switcher app). I was able to get GO Launcher to install and work, but I'm not able to add widgets to the screen (not sure if DPI settings need to be changed or what for the Add menu to display properly) so for now it's a bust. I'll try again tonight after disabling forcing landscape and allowing screen rotation.

The DVR system seems to work well in indoor tests (came with an 8GB memory card, too) and recording/playback can be controlled via the head unit or buttons on the camera. Access to view it and change the settings is done by opening the AUX app. It transfers video to the AUX app by "sharing" the AUX 1 video input. It also transmits commands to/from the DVR camera with an on-screen display accessible in the AUX app. I did an experiment where I hooked an Xbox into the AUX 1 input and verified it worked, then turned the camera on. The screen became distorted as the two input signals mixed and interfered with one another, so if you are actively using the DVR, you can't really use AUX 1 input. Focus on the camera is fixed at infinity (I think).

I tested the auto-on backup camera system and it worked. The unit did not come with a backup camera, so I had to make do with a Xbox and jumping the reverse signal to +12V. I'll be ordering a backup camera soon (probably this one: http://www.aliexpress.com/item/Car-...0-Degree-Waterproof-IP68-8-IR/1262490422.html ).

I ordered the headunit and the DVR separately. When I ordered, I specified that I needed the universal wiring adapter (as my car is not a EU-spec Nissan), English language, and USA maps.

One box arrived and inside the box was:

Headunit

2 metal mounting brackets

Nissan wiring harness adapter (bonus for bench testing! de-pinned this and inserted the pins into ATX power supply outputs and 2 car speakers)

Universal wiring harness adapter (all ends labeled & pre-stripped)

Analog? amplified TV antenna (3.5mm jack & +12V and GND leads). I tested it but no stations were picked up as we have switched all broadcasts to ATSC.

GPS antenna

Micro Wireless N adapter (plugs into one of the USB port pigtails in the back, and is about the size of a Logitech wireless transmitter)

iPod adapter cable, old style, not Lightning (plugs into specific iPod labeled pigtail on the back)

Short USB to mini USB cable & short USB extension cable

DVR camera w/short pigtail

DVR camera cable (long) with HU pigtail connector and +12V & GND leads
