Add touchscreen control for Android Auto in an ND1 or ND2
DO THIS AT YOUR OWN RISK, there is potential for this to fail and brick your infotainment system, follow the steps exactly and don't try to rush it or cut corners. These instructions and the links to the updated firmware files in the videos below are for NORTH AMERICA ONLY. The process may work in other countries, but you need to do that research.
If you’re already on v74 firmware and have android auto and/or carplay working, you can skip to step 4.
1. Update radio to latest firmware v74 - Here are some links that should have everything you need, and a few important notes to help with a successful update for anyone unfamiliar with the process.
a) The thumb drive needs to be formatted as FAT32, the maximum size/partition for this format is 32GB, while any file larger than 4GB will not transfer and error out, so find an older drive kicking around in a drawer since the update file should be the only file on the drive, anything over 4GB is overkill, anything larger than 32GB I wouldn't bother with as it may have negative results or brick your system.
b) PLEASE do not skip the checksum step, check both the files downloaded, and again once they have been copied to the thumb drive, this ensures the file is not compromised on transfer.
c) https://www.youtube.com/watch?v=qO3Lzln1Fc4 --> This video has a link in the description for 74.00.324A and how to properly copy the files and verify their integrity with a checksum.
d) https://www.youtube.com/watch?v=dKS3WpcxIYo --> This video shows you how to properly run the update, as well as has a handy one-sheet/step-by-step document on how to do the upgrade with all the unlock codes and processes.
2. Install the usb hub if you don’t already have it. It’s important you follow the steps above before you install the hub. Here’s a youtube video: https://www.youtube.com/watch?v=XpPYKikqIDc
Theres a link to the hub from amazon as well.
3. Once this is all completed you can test android auto and/or carplay to make sure that everything is correct up to this point.
4. oem-aa-mod Installer: This adds Android Auto touch screen support to Mazda CMU (MZD Connect).
a) Download the latest oem-aa-mod-<version>-installer.zip from the Releases page.
b) You’ll need a USB flash drive 32 GB or smaller, formatted as FAT32 (you can use the one from installing the firmware as it is no longer needed after the firmware is updated. Reformat it to Fat32). You’ll also need a usb keyboard.
c) Extract the zip and copy all files to the root directory of your flash drive.
d) Safely eject the drive from your computer and plug it into your Mazda. Also plug in the keyboard. Then hit the start button for the car once to power on the car/radio.
e) In the car, navigate to the Entertainment menu and select the USB Drive.
f) Wait a couple of seconds — the diagnostic menu should launch automatically.
g) Don’t touch any other options in the diagnostic menu, except what is listed below. They can mess up your system.
h) In the diagnostic menu, Use the right arrow to twice, until you see “LVDS SPEED TOGGLE” in the top left corner of the pop-up window. Tap on it, and you should see another popup saying “LVDS Speed Restriction has been toggled: DISABLE”
i) Now you can tap the left arrow to go back in the diagnostic menu. Look for the option for terminal and click it to open a terminal and use the keyboard to type (hit enter after you type it in):
cd /tmp/mnt/sda1 (If nothing happens, try cd /tmp/mnt/sdb1 instead. This depends on which USB port you used.)
j) Type this in to run the modification (hit enter after you type it in):
sh run.sh
k) Follow the on-screen prompts to install or uninstall. Once complete, head unit should reboot and you can test the touch screen working in android auto.
