Just picked up what appears to be a newly designed (or redesigned) Volkswagen headunit using the Allwinner T3 Quadcore from Umecity. I didn't see any threads matching the hardware listed, so I thought I'd start a discussion thread for it. The unit I purchased is only a few centimeters deep, and seems to use several upgraded ICs (radio and amp, specifically). The images of the system indicate a hardware date of March 31st, 2017 (printed on the board), and a system date of April 10th, 2017.

FIRST IMPRESSIONS
This is probably one of the nicest car stereo designs I've seen. Very thin and light, with what look to be well thought out button placement for a 9" unit (capacitive buttons in the bottom bezel). The unit was well packed, and arrived in good shape with no damage. The vendor has also been super responsive and helpful.
INSTALL COMMENTARY
The unit is incredibly shallow, giving you way more space for cabling. Unfortunately, it didn't come with any documentation, or even a wiring diagram. Luckily, most of the connections are pretty obvious.
The combined the VW ISO1, and ISO2 connector harness is a nasty spaghetti cable, but manageable with some careful sorting, and zip ties. If you use CANBUS, don't connect the orange power connector to your ISO of choice. This will make the stereo not shut off when the car does.
USAGE REVIEW
Startup time: Took about 30 seconds from no power to radio on the first boot. Unit will stay in standby for up to an hour, then power down to preserve battery.
Responsiveness: Touch screen and capacitive hardware buttons are very responsive.
Display Quality: Screen is super clear and bright, with good viewing angles. Brightness and panel lights come up or down based on the headlights.
GPS: GPS found lock after only a few seconds.
Wireless: Wireless range could be stronger. That said, the unit did eventually see my home AP from the street and connected with 2 bars.

ISSUES WITH UNIT
- Fender Audio: Individual audio channels are way too loud. Listening to car on volume 3-4 starts to get painful. Volume control goes up to 40 or so.
- Can't install Android Auto through the Play Store directly. Will need to be side loaded.
