[Android Stick & Console RockChip based Computers] Sincidius:
I decided to make a post on this due to the fact that I have decided to get a different phone (iPhone), but wanted to keep my AppRadio 3 function. I decided to make this to assist anyone else who would like a more stable solution in their car.

*****Note*****

1. This will go over the initial setup of AppRadio Unchained with a MK809III stick. I am using V 5_2. I bought this from Amazon. It came with 2GB RAM, Quad Core, and a skinned 4.2

2. Almost all Android sticks are a little different. Most stock roms work fine, so don't attempt to load a different ROM unless you are 100% sure you have a one that is built for your EXACT stick.

3. The final goal is to have something that functions mostly off no internet connection. WiFi Tether works, but I wanted something I could use daily without the extra step.

4. This step will work initially. I will be expanding/editing this to expand of a fix for Google Music Storage to the SD card (not NAND) and ROM Flashing (Please see above).

5. Do this at your own risk. I AM NOT RESPONSIBLE FOR ANY DAMAGE YOU MAY OR MAY NOT DO TO YOUR DEVICE OR RADIO.

***** Lets Begin******

You will need.....

- Android Stick MK809III (These steps do not deal with the ROM so any 4.4+ ROM Stick should work)

- Appradio 3 (Support these guys!)

- Bluetooth Auto Connect (Play Store, Free)

- Google Maps or Sygic (Sygic cost $25 for NA maps, again, how data depended do you want to be)

- SuperSU (Play Store, free)

- Kingo Root (PC app, this will be a lot easier if you have a laptop)

- Driver Assist (PC app, search "Release_DriverAssist Rockchip", this will make driver install a lot easier for you, especially if you are on Windows 8+)

- USB Keyboard/Mouse (USB Wireless Mouse works, but a mouse alone is a PITA)

- Smaller HDMI Input Video Source (I used a monitor. This will help when establishing bluetooth)

- A good USB cable (not the one that comes with the Android Stick, I used my LG G3 cable)

1. Boot your Android Stick for a first time. Verify that you have Android 4.4+, the Play Store, and that your HDMI output is set to 720P! (settings - display - output) This is necessary for Appradio & touch.

2. Go to settings - about device. Click on build until you are a developer. Go to developer options & enable USB Debugging mode.

3. Go to settings - security and enable install from unknown sources.

4. On your PC, install the drivers through DriveAssist.

5. Install Kingo Root.

6. Connect your Android Stick to the TV through HDMI only. Connect your PC to the Android stick's OTA plug, not the power one.

7. Once it powers on and settles, go to settings - USB. Select connect to PC. Your computer should start installing drivers for the stick.

8. Once installed, open Kingo Root. It should find your device and be pretty simple at this point, just don't install the free browser they offer.

9. Once Root is complete, Install SuperSu and run. Install binary, but do no reboot. Kingo will request Root access. Grant.

10. Go to Settings - Apps. Go over to All apps. Remove all Kingo Apps, we use SuperSU.

11. Install Appradio Unchained & Bluetooth Auto Connect.

12. In AppRadio Unchained, select the following options....Invert XY, Start/Stop on HDMI, and Start on Boot

13. In Bluetooth Auto connect, select the following options....Bluetooth On, Screen On, Control On, Device Connect

14. Go to your car or as close as possible with your monitor (or whatever), your Android Stick, and keyboard & mouse. Start up your android stick and make sure AppRadio Unchained & Bluetooth come up on boot.

15. Cut your car on. When the AppRadio boots, go to your Android Stick and go into settings - bluetooth. When you see ApprRadio connect. Once it connects, let it download phonebook ( I know).

16. Go back to Blueooth Auto Connect and look at devices. Make sure that AppRadio is selected.

17. Power off your car and plug your Android stick into the Appradio (HDMI and USB through OTA plug)

18. Start your car up & click past the OK message (Using fingers at this point, no mouse should be needed). Wait and you will see the connection item, it will fail. Don't worry. Just press retry & the Hard home button. This will happen about 3-4 times because your Android Stick is booting up.

19. Finally you will see the Bluetooth on your radio connect and Appradio Unchained will finally boot on your screen.

I installed two USB wires, one that goes from the radio to the OTA port, and one that goes from a power switch to the power connector on the stick. When I get into my car, I flip the switch and start up. After a minute I start the car and press the OK for the warning on my radio. This gets past the connection error and boots right into AppRadio Unchained. I have left this on overnight & not had any issues, but I don't want to chance draining my battery.

Please feel free to post any questions.

Will update 6/18 for advanced (details below post)
