[FYT Android Head Units] Savvy Tofu:
What's Working for Me Android 6.0.1 JY-TM138N2

This post is exclusively what worked for me and to say thank you to our brilliant developers and modders! Thank you so much! My car now feels like it’s worth so much more. I hope this can help others with their install who are just picking a unit up now and save you >150 posts of read. This is my first post, please let me know if I'm causing trouble. Will update with links once I reach 10 posts (blank spots).

Goals:

•	Install an android head unit for Torque Pro and RaceChrono lap logging

•	Allow Bluetooth tethering for spotify

•	Allow AutoMate to control my music, navigation, and calling/texting

•	No internet use Google Maps navigating

•	NO STEERING WHEEL CONTROLS

•	NO AMP INSTALLED – I’m okay thanks

SECTION 1: Hardware

Vehicle:

2015 Subaru BRZ Limited Edition

Head Unit:

JOYING 2GB RAM 32GB ROM TOYOTA UNIVERSAL CAR STEREO FOR SALE 8 INCH DOUBLE 2 DIN ANDROID 6.0 MARSHMALLOW CAR SOUND SYSTEM

SKU: JY-TM138N2

Android 6.0.1 Marshmallow

CAUTION: This is their newest unit and NO ROM AVALIBLE AS OF THIS POST 7/15/17 PER MFG. Proceed with caution :)

Harness:

JOYING® TOYOTA HILUX WIRING HARNEDDCAR AUDIO STEREO RADIO PLUG LEAD WIRE LOOM CONNECTOR ADAPTOR

SKU: THILUX

•	I replaced the original audio USB AUX port with a generic one which is compatible with the head unit.

•

•	There will be a few wires that will not connect (2-3 wires), but I haven’t been able to identify them nor have noticed anything missing after a month of use.

•	No, this harness does NOT come with the unit. You can try emailing them to see if they’ll replace the packaged one with the hilux one?

Q: Will it fit your BRZ standard, GT86, or FRS?

A: Pull the unit out, look at the back, take pictures and compare them to the harness. If the number of pins match up it will fit! If not email the MFG.

Backup Camera:

N200 Rear Backup Camera

•	You’ll need to tap the 12V wire and ground the grounded wire to the chassis (any screw attached to frame of the car) and of course connect the yellow RCAs.

•	Identify your backup wire and connect it to the harness wire labeled “break” to allow the backup camera to automatically turn on when in reverse.

•	This link was instrumental to my install:

OBD II Unit:

ScanTool 426101 OBDLink MX Bluetooth: Professional OBD-II Scan Tool for Android & Windows

•	Works! I wanted a unit I can leave plugged in and forget about it.

•	It has a blue light on at all times which is noticeable at night for you OCD people.

Remote Controller:

Satechi Bluetooth Button Series (Media Button)

•	DOES NOT PAIR – unit keeps asking media button to type in a code, but that’s not possible since it’s not a keyboard.

•	I don’t have a steering wheel controls, I thought I could use this instead – will update if fixed

SECTION 2: Rooting

CAUTOIN: CREATE BACKUPS OF ANYTHING YOU MODIFY – this is the only warning

Use factory reset under backup and restore password 3368 to revert to factory settings. It has resolved some of my Bluetooth and system failures successfully. Do not re-root once factory restored.

Q: How do I open CMD.exe as administrator?

A: In your search bar or run, type in CMD and right click it. It will say C:\WINDOWS\system32> or similar if it worked. If it failed, it will say C:\Users\User_Name>.

Q: How do I navigate CMD?

A:

Q: I have a MAC

A: I do too, just borrow someone’s PC w/Wi-Fi

Q: I typed in my IP address, why isn’t it working?

A: Type in the IP address displayed by the ADB program on your head unit, not your laptop IP address

SECTION 3: Bluetooth

NOTE: No, it’s not known at this current time how to enable the original Bluetooth menus. All options I’ve tried have resulted in either soft bricks or endless boot cycles. If like me when you factory reset and your OEM Bluetooth app didn’t install, just install your backed up original APK file by clicking on it and installing from an unverified source.

1.	First install ES File Explorer Pro or your favorite file explorer with root access.

2.	Activate root explorer at the bottom of the menus and allow SU permissions

3.	Download treel’s apk to a usb file

4.	Use ES File Explorer to perform the above

5.	USE THE REPLACE FUNCTION – replacing a file will retain the original file’s permissions.

6.	DO NOT INSTALL ANY APK by clicking on them! Just replace the stock apk with the new one and leave it alone.

•	OBD II and phone tethering working great through Bluetooth! Thanks!

PAIR THROUGH THE NATIVE OEM UGLY BLUETOOTH APP!

SECTION 4: No Kill – task killer

Every time I get in the car, the machine will forget my settings due to task killing. This should allow it to behave much more like a tablet.

1)	Download gustden’s file to a USB

2)	Use the above file with gustden’s instructions here

SECTION 5: Software/Apps

Software:

•	Torque Pro – It does have typical noticeable Bluetooth lag, but it’s clinically insignificant when looking at your data

•	RaceChrono – GPS lags, but haven’t been to the track to test it fully

•	Bluetooth Tethering Pro – AMAZING, you don’t need the pro version, but it works so well I wanted to support his constant updates. Caveat – Bluetooth tethering will prevent your phone from being able to make calls or texts from the native Bluetooth app we are restricted to.

•	Nova Launcher Prime Pro (necessary for Pro) – LARGE ICONS are totally worth it while driving. You need to change the car settings to choose this launcher by hand

•	Spotify – Why do you take so long to load?

•	Spotify Shortcut – AWESOME! One of my pages on my launcher are entirely playlists. Just click and you’ve driving with a brand-new playlist!

•	Titanium Backup – Working! I keep old saves just in case an update causes instability.

•	ES File Explorer Pro – Working!

•	Google Maps – No, you can’t install a map for the country, just small locations at a time.

•	Here – YES! You can install a map for the country – currently backup

•	AutoMate Pro – I usually just keep this program open while daily driving

o	Do not set as launcher!

•	Root Software Misc.

•	Google

o	TTS installed

o	Google app is not due to system crashing on reboots

You may PM for questions, but as a newcomer I'll do my best to assist. Best of luck getting your system to work!
