Is AIO compatible with my FW version?
AIO IS COMPATIBLE WITH ALL FW V55, V56, V58, AD V59 up to V59.00.500
AIO is also compatible with version 59.00.502 - 59.00.550 ONLY IF YOU HAVE DONE THE NECESSARY STEPS TO ENABLE TWEAKS INSTALLATION (Read This Thread For More Info)
This can be done by installing autorun & recovery scripts before updating
If you never had an earlier FW then the only way to gain access right now is to via serial connection
All Compatible Firmware Versions Are Listed Here. AIO will read out your FW version at beginning of installation, if it’s not compatible the installation will abort.
Is there anything to note, if I use a MAC?
If you are using a Mac or Mac formatted thumb drive make sure there are no hidden files on the drive.
The drive should be formatted Fat 32 on a PC if possible.
How long does it take till the installation starts?
This can take from 30 seconds to 20 minutes. Certain factors can delay the start so be patient.
How long does the installation/uninstalling take?
Up to 20 minutes if every tweak has been selected (especially custom colors and jci backup).
If the ‘zip jci backup’ option is chosen it can take up to an 45 minutes.
Do I have to uninstall a tweak before installing it again?
No, you can install over old versions because during installation the tweak will be deleted and then reinstalled.
You can install every tweak over an older version of the same tweak, you never have to uninstall before.
Do I have to use same AIO version for uninstalling the tweaks?
No. You can use latest AIO version for that.
Will all previously installed tweaks be automatically uninstalled, if I do not choose them with a new installer?
No. Only tweaks you have chosen to uninstall will be removed.
What is “autorun & recovery?”
Autorun & recovery are a set of scripts that will automatically regain SSH access and allow for tweaks to be installed when updating to firmware v59.00.502+ or after gaining serial access. The recovery script lies dormant until it detects it is needed then runs automatically in the background without you even noticing that it is fixing the issue.
Is it one time installation or needs do be done every time before firmware upgrade? Does it need to be installed separately or can be done with other tweaks at the same time?
They only need to be installed once separately from tweaks then you can forget about it and it will do its magic when the time comes. You don’t even need to reinstall the scripts after updating, they will persist through firmware updates and will automatically run and repair your system after the update is complete.
What are the other options under autorun? Do I need them?
There are a few extras you can install with the autorun script Auto WiFi AP, Auto ADB, and Dryrun. You don’t need any of these for the recovery scripts to work these are just additional ways to test/access your system.
- Dryrun: is only for testing the installation is successful, you only need it the first time you install then you can delete it.
- Auto WiFi AP: Starts a WiFi AP (Access Point) coming from your CMU. You have to set the SSID and Password used to connect just like you would a router. If you dont set them it will not work.
- Auto ADB: This one is my favorite, on boot it starts an adb reverse port from 2222 to port 22 that can be used by any android device (with developer mode activated) to connect directly to the CMU via
SSH --host=localhost --port=2222
Can tweaks be installed after running the recovery script?
You can do everything normally after installing the autorun & recovery scripts. You will not even notice them, you can just forget about them and rest easy, they will be ready when you need them.
If something goes wrong, how can I help you to help me?
During installation/uninstalling, a log file is created (AIO_log.txt) and some additional files will be copied on the USB drive.
Please make a ZIP file of them (complete root of USB drive) and send that to me or upload somewhere (e.g. Google drive or so) and send me the link.
You can download this tweak to make a copy of your jci folder, zip and upload if we need to take a deeper look into your files to find the issue.
Why does AIO reboot automatically at the end?
Because some tweaks are applied on the next boot or during the system boot process. Also, it puts the system back into read-only mode.
If I want to go back to original state but I forgot the tweaks I’ve installed, what can I do?
It doesn’t matter if you choose tweaks for uninstalling that you haven’t installed. AIO is designed to discover and revert only the changes that have been made by AIO with a few necessary exceptions. Uninstalling all tweaks (and choosing default color scheme and background) will revert your system back to the default state. Any changes made outside of AIO are your own responsibility. There is also a “Full Restore” tweak that can be accessed through the dropdown nest to the Start Compilation button or the side menu. You can use the to safely revert your system to “stock.” A third option is in the AIO Tweaks App. Choose the “System Restore” option and your system will be restored EXCEPT for the default Red color theme file, that you mush revert with AIO by selecting the “Custom Infotainment Colors” Tweak and Red (Default) Option.
How do I reboot the system?
Press NAV+MUTE+BACK for 20 seconds.
Can I install AIO even from an SD card?
No. SD card slot in the car is ONLY for satnav maps. You need to use USB port in the car, so either USB stick or USB-SD card reader with your card in it.
This has changed but requires a little bit of DIY => Autorun Script
How can I enable Hotspot on MZD system:
Try the following: (*Before v58 only)
- Open diagnostics menu (buttons Music + Favorites + Pwr / Mute and hold until menu appears)
- Hold down “DEL” until “JCI Test Mode Active” appear at right black box (15-20 sec.).
- Press “11” and then press “Enter.”
- Select script WiFi AP Toggle
All FW Can Activate Via SSH run the commands:
/jci/scripts/start_wifi.sh /jci/scripts/jci-fw.sh stop /jci/scripts/jci-wifiap.sh start
Then the access point of the car is running, you should see a WLAN “cmu …”. Simply log in and then access via IP 192.168.53.1 on the system. The AIO Tweaks App also had a Start Wifi AP button, this is the easiest way to start it. —
Why did my compass stop working?
Enable touchscreen while driving actually does 2 things. 1. enables use of touchscreen while driving and 2. enables list items (such as text messaging and enter address for navigation) that are normally disabled while driving. The latter of these has a side effect, it disables the compass (and cluster compass if available). To enable the compass and use of the touchscreen (with disabled list items while driving) choose the ‘Fix Cluster Compass’ under the enable touchscreen while driving tweak.
I don’t get GPS data after installing speedometer
This happens with some newer FW versions (56.00.51x). Try this to get GPS data for these FW versions:
- After opening the doors (or trunk) at least wait 35 seconds, then start the engines
- Before starting the speedometer app, shortly start the NAVI app before (works too, if NAVI app was open if engine was stopped)
- Unplug and re-plug the NAV SD card (should be avoided)
When do I need the to use the SwapFile Tweak?
If you use a navigation SD card and/or use the Video Player app or Android Auto often, you want to be using the swapfile. The Mazda Navigation System occupies a HUGE portion of your active memory. Those 2 apps require a pretty substantial chunk of memory for themselves to run smoothly, swap memory is the solution designed to solve this very issue.
When the system runs out of active memory and requires more in order to complete the current process, memory will swap (for empty memory space) an unused (or cached) part of itself with the swap memory to use as active memory until it is no longer needed or the swapped process is called, then it swaps back.
TIP: Swap memory is mounted during the CMU’s boot process and is also mounted when using the VideoPlayer app. Some have found better performance by connecting the USB drive after boot is complete so the swapfile can be mounted by the videoplayer app.
NOTE: Memory swap management is not perfect and performance issues can emerge in certain situations such as switching rapidly between many processes.
I have a question/problem with speedometer.
What are the video specs for playing videos?
Video: MP4, AVI, FLV, WMV; Audio: Stereo MPA
A good format to use H264 video codec and MPEG-4 AAC audio codec in video files
360p quality works best (and still looks great)
I can’t play videos. What can I do?
Check out the VideoPlayer Page Try the following:
- REMOVE NAV_SD CARD
- Put all videos in “movies” folder at the USB drive root.
- Unplug all other USB drives, especially one, with many MP3s on it.
- Close the player and start again
- Turn the car on without the USB drive plugged in
- Copy only one mp3 on your video USB drive
- Copy only a few videos on your stick (you don’t have to delete, rename to ._mp4 is OK too, so that they will not found anymore)
- Try the SwapFile Tweak
- Reboot your system and try to play a video right after that
When I play a video with the VideoPlayer app I hear the radio??
You have to manually switch the audio channel to USB (or Bluetooth) and play a silent audio track or pause the audio to play the audio from the video by itself. The VideoPlayer app uses a separate audio channel but shares the volume so the active Mazda audio channel needs to be paused or silent.
TIP: If audio is playing on the USB channel already When opening the Video Player from the app menu, press the Entertainment (Audio) button to pause the music player. This will only work once before playing the first video then the button will function normally.
In entertainment window, pause-on-mute works perfectly. But if you leave from the entertainment window, “mute” mutes sound but does not pause the song.
This behavior is correct and as expected. The pause command will not reach the player if you are in any other app/menu.
I applied the Remove Message Reply tweak but I still get the message on my texts?
In order to apply this tweak you have to do a factory reset of ALL settings. Unfortunately this is the only way to apply that tweak but here is a tip when applying.
TIP: Edit the values of the PresetMessages nodes under your language in file
config/message_replies/jci/settings/configurations/blm_msg-system.xmlto start with your own custom preset messages after the factory reset. —
I want to change the order of the audio sources. How can I do that?
You have to edit
around lines 624 - 637
Be careful, the last line must NOT end with a comma or you run in to boot loop!
Why there is a tweak for backup the /jci folder, but no script to restore these files?
This is just for anyone who would like to learn about the files within their CMU. It is not necessarily for recovery because only about 1% of the files in the jci folder are modified so replacing the entire jci folder is overkill to say the least.
It is also for finding issues, if any exist they can usually be found in those files.
CastScreen-Receiver Is Not Working?
- Make sure you have enabled USB debugging in developer options and that when prompted you gave the CMU debugging authorization.
- Make sure you have given the App permissions on your phone to allow castscreen app to use usb storage if the app never prompted for that reinstall it.
- Try disconnecting for at least 5 seconds and then reconnecting your phone.
- Try connecting the phone in different modes such as MTP or PTP.
- Using CastScreen together with AA installed can be tricky, a trick is to put your phone in PTP mode to disconnect from AA. Then do not disconnect your phone until you are finished screen casting or AA will launch and steal focus.
- Try connecting to SSH through USB through localhost:2222, if you cannot connect then something is wrong with the CastScreen installation. If you get an error like: connection closed by foregn host or something like that try toggling wifi.
- CastScreen-Receiver uses the same module as the video player to display and therefor can suffer similar performance issues if the nav_sd card is being used. If you are experiencing issues, removing the nav card will improve screen casting performance.
Whats Up With Android Auto Headunit App?
Android Auto Headunit App for MZD is an ongoing development by many developers all around the world. The project was forked from a fully reverse engineered AA headunit app by the late great Mike Reid and ported to the MZD infotainment system where it underwent development by some extremely talented developers. The Mazda community waited for an official version to come out but was met with empty promises, driving a few determined hackers to create a fully working version first. As of now Android Auto Headunit App ver.1.08 is free of major bugs and works as it should well before an official version was released… if that ever even happens.
How Can I contribute to Android Auto development?
What about Apple Car Play
As far as I know there are no community projects involving Car Play and the MZD system and I wouldn’t hold my breath waiting for Mazda to release an official version any time soon (or ever). Personally I will never own an iPhone because Androids are far superior although I don’t hate apple or anything, I do have a Mac as one weapon in my computer arsenal. Having said that, even if this project existed I probably could not contribute due to my lack of iPhone… Sorry.
Can you write this or that tweak for us?
By now I have studied the inner workings of the Infotainment System so well I could probably go work for Johnson Controls or Visteon. There are still things that are very tricky, dangerous and/or impossible to pull off but if you have an idea Shoot me an email and I will give it a shot (Except Car Play, PLEASE DO NOT REQUEST CAR PLAY!!)
