Joying has new 2gb RAM and 32GB memory units on the way to the market. Shipping says ETA of late November.
Guess my 1gb unit will be right back on the shipping truck back to Amazon...

Can someone who has used the OS2X module, tell me how they wired up the SWC wires?
EDIT: I found the GR w/WH wire and the Yellow (battery) on the PAC harness. I re-read the 1st post and it says to wire the gr/wh wire to KEY 1, but then the yellow to GND lead. Shouldn't the yellow be hooked to ACC +12v?

The PAC has two types of steering wheel control (SWC) connections; a mini phono jack and a single blue/yellow wire. It also has a 10-position switch that determines SWC signal compatibility with mainstream HUs. This HU has two wires labeled KEY1 and KEY2 and according to the documentation works with only resistive signals like the Corvette's (see Volume 1 of the shop service manual for schematic). I tried the single wire, and I cut off the phono jack and tried the red and white wires, and I tried all ten switch settings, but nothing worked and I couldn't make sense of the PAC SWC signals with my multimeter. I solved it by cutting the yellow and green/white wires from the PAC that correspond to the purple (6) and dark blue (7) wires from the car and connecting them to the KEY1 and GND leads from the HU. The HU immediately recognized the buttons and made it easy to map them to the desired functions (my 1-6 button now controls mute).
The PAC harness brings its power in on the yellow wire and loops it back out on pin 6 to power the car SWC (purple wire on the car side of the connector). I believe yellow is constant power rather than switched, so I didn't care for that approach anyway (why energize the car SWC resistor tree when the ignition is off?). Cut that loop and connect the outbound yellow wire on pin 6 to the KEY1 wire. The SWC circuit becomes:
HU KEY1 <--> connector side PAC yellow pin 6 <--> car SWC purple pin 6 (+)
HU GND <--> connector side PAC green/white pin 7 <--> car SWC dark blue pin 7 (-)
HU KEY1 <--> connector side PAC yellow pin 6 <--> car SWC purple pin 6 (+)
HU GND <--> connector side PAC green/white pin 7 <--> car SWC dark blue pin 7 (-)

Thanks!!! You are correct, I was backwards. After the drive from NOLA to Houston yesterday, my brain was apparently not functioning properly. The last quote was exactly what I was missing.
Sidenote - the new 2GB RAM and 32GB Flash Joying unit is FAST. Very Fast. I got everything else wired in and was able to play around a bit with the unit. UI is good enough, and I can't wait to pair my MX I had from my truck.

Bookmarked for my installation attempt this weekend
and with a backup camera
I've never installed a car stereo in my life. I've researched how to do this and bought all the items needed (PAC module, ground loop isolators, Double din installation kit. I imagine this 3 hour job will take me at least 8.
Pretty excited to update the stereo on my C6..

Spent about ten hours doing the entire job. Never installed an aftermarket radio before. Love having Waze, Spotify, and the beck up camera. The unit came with a usb on a long cord, wasn't sure what I was going to do with that. That's the only thing I think I could have done a little better if I had the proper tools.

Those are among the questions answered in more detail earlier in this thread for the model I installed in 2014 as well as newer models installed by other members of the forum, but to summarize briefly:
yes
depends on the nav app that you choose
iGo and Sygic are among the options that have offline maps and POIs with worldwide coverage
yes
no HUD directions, voice commands depends on the nav app that you choose
yes bluetooth, I have seen posts on use of the OEM mic in other threads, but I use the HU's mic
mine is wired to the OEM amp and speakers and sounds at least as good as the OEM HU (and offers far more options for equalization and other acoustic customization)
yes

I remain so pleased with the Android head unit that I installed in my C6Z nearly three years ago that I just bought another one, this time for my 2009 Toyota Rav4 Sport V6. These are improving all the time... this one (C1067106A3 from "BonRoad") has double the CPU cores, twice the RAM and ROM, higher resolution, custom form factor and plug-and-play installation (took less than 30 minutes total), all for only $287. Impressive!

Is it instant-on yet or still a ~30 second boot time?

Android still must boot, which happens a bit faster on this unit (closer to 20 seconds). As with the older unit in my C6Z, only the backup camera is available immediately (presumably because the OS is bypassed for that function). It's particularly annoying in this case because the Rav4 cuts power long enough to force a reboot when switching from ACC to START to ON. I am preparing to add a capacitor and diode to keep it running for a few seconds when power is cut; perhaps a similar approach could be employed to anticipate the need to boot when entering the vehicle (e.g.- tie in to the dome light circuit)...
