[Android Head-Units] sciallo:
My unit showed up yesterday, very unexpectedly! The FedEx tracking number I was given still shows "not found", the unit was delivered yesterday by DHL ...figures :)

I negotiated an extra set of wires, that will be really handy once I have the unit installed if I decide to take it back to the bench for more mods. But also, as other expressed, I'd be interested in seying a picture or drawing of the ext. microphone connections someone got on the harness with the I-pod connector. I'd look inside and see if that is connected and just missing from the harness...

I got the TH8681GA model with the same exact face/button configuration as the original "OUKU" TH8581GA

I havent' had much time to play with it yet. And won't do too much for a while as I'm going to be out of town for a few. So far, at first glance:

Android 4.1.1

MCU: 4.0.6-1-10-0301

System: 2.6.60

DVD: 2.13.11-hd860mc

- I tried to set the right knob push (tune in my case) to brightness... Turns out I can't set that knob to anything, it sticks out further than the volune knob and seems flimsy, it does "click" but does not appear to work (it does work turning it for tuning. Does anyone have the same model? could you let me know if you can assign something to that knob push? Trying to figure out if it's defective or just designed that way...

- My USB hub works fine. Might be overkill with 10 ports, but I'm happy it does. Once in the car it will be powered by this 3A DC/DC converter, 1A more than the wall adapter that came with it. I tested it connected to the PSU's 5V out with wi-fi, keyboard dongle (logitech K400), and 2.5 external SSD hard drive, pus a couple of Bluetooth dongles wich of course didn't work but still added some load to the test :) Interestingly enough it works powered or unpowered, though I doubt it will be able to theke too much load when bus powered if things like hard drive and phones charging are connected...

- I was disappointed to see the "hold home button" trick to shut off radio and other "native apps" does not work like it did with the OUKU. I guess we're stuck with some worthless thing always coming up at startup for now uh? On second thought, I just tried: Opening the Disc app without a disk in the slot does the trick, it opens and immediately closes. When powered off and restarted it comes up to the desktop... good enough for now :)

- I was pleased to see there is some sort of "Sleep" Interesting how that seems to be an alternative "model" selection in the menu. Once selected it's almost like it loads a different version firmware and reboots... anyone knows more about that? what else changes between models? (I have two choices there, is there models/firmwares with more?) As already mentioned this does not work on red wire disconnection (the unit will still shut down) it goes to "sleep" on long press of the vol. knob in my case. Any other way to put it to sleep? specifically, a command... that will help with my plan for IOIO

- LED colors are aqua blue as opposed to bright dark blue as it was on the OUKU... I guess I won't feel as compelled to do the LED swap as it should be pretty close to my dash illumination now :) Of course I might eventually get brave enough to pull a whole different harware hack on the front panel to interface with IOIO for led dimming and hardware buttons but that will probably be a forum thread of it's own when the time comes...

...And that is an awesome feature I'm adding to the list of IOIO hacks
