Well, I stand by my recommendation on page 1 of this thread.

That is the OBDLink MX Wi-Fi. My OBDLink MX Bluetooth connects 100% of the time.

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?

You might be confusing PAC side vs. connector side of the two cut PAC harness wires.

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).

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 (-)

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..

Shoot. I just ordered a cheap-o 1GB unit from Corehan. ($197.00) I wonder if it is worth it to return and get this other one instead.

Not that hard. Don't be a fool like me and cut off you PAC adapter rca jacks. Still do not know what I was tinkling there.

LOL, I actually read your posts about that the other day. I will definitely leave those as-is.

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.

Looks great! I took one USB and ran it into the sender console and ran the other one into the glovebox.

yeah,I don't think Apple is making head units yet, lol.

But as an iphone user (which I love), I have to admit that I'm happy with my Android HU.

I'm not sure what is meant by "for Iphone." It is Android but works with Android, iPhone, Windows Phone, etc.

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)...
