What changed from version to version, newest first. Download and instructions: ADC. Listed are the versions that were available for download; in-between versions that only ran on our test head unit are included in the next one. Ran says where a version actually ran — everything else is untested.

• Echo on calls: when you phone through the car, the other person hears an echo. Still open.
• CarPlay over a cable we have never tested: with ADC the manufacturer's cable CarPlay is switched off, and ours has never run. It may not work.
• Bluetooth music while CarPlay runs stays silent until you pick Bluetooth as the source in the car's media app — otherwise the speakers belong to CarPlay.
• App build 104: our menu rows are hard to read in day mode (white on light grey); at night they're fine.
• Going back to the stock firmware: the Connect app's check only covers its own Revert button. If the head unit restarts while a stock-firmware stick is plugged in, it flashes it without any check — for example after a factory reset, and on cars without the USB hub already when you switch on.
• Storage: our backups under /sdcard/OpenAiways/ stay there, even after going back to the stock firmware. If the storage is full, the next installation stops without changing anything (it needs about 50 MB).

Connect app 1.9.22 · includes the internal version 0.14.8

• New: two-finger zoom in Android Auto — maps zoom with two fingers. Rotating doesn't work; Android Auto apparently doesn't allow it on the car screen.
• Fixed: 0.14.7 read the MCU version wrongly (e.g. “702” instead of “060”). So when reverting it refused every stock-firmware stick with a different app build, even fitting ones — such as the 060 stick in a car with 052. It only ever refused too much; it never let an unsuitable stick through.
• Changed: the message for an unsuitable stock-firmware stick is now short and writes the versions the way Settings › About does: “Stock version _104 denied. Incompatible with MCU _060.”
• Ran: on our test head unit (app build 060): installation, the stick check (104 stick correctly refused) and two-finger zoom (with the same program files). CarPlay not re-tested.

Connect app 1.9.19

• New: a safeguard when reverting to the stock firmware: the Connect app refuses a stock-firmware stick whose apps do not fit your car's MCU (Head unit versions), and then changes nothing.
• Bug (fixed in 0.14.9): the MCU version was read wrongly, so fitting sticks with a different app build were refused too.
• Ran: only after it was published, on our test head unit (060): installation without warnings, Android Auto ran. The stick check correctly refused the 104 stick, but named a wrong MCU number.

Connect app 1.9.18 · includes the internal versions 0.14.3 to 0.14.5

• New for app builds 060 and 104: the same menus as on 052 — Android Auto with switch, page and tile, a WLAN switch of its own, switching phones with one tap in the Bluetooth menu. Up to 0.14.2 these builds got only the core without our menus.
• Fixed: in 0.14.2 the Connect app copied an old version of the SSH server back every 5 minutes; it no longer does.
• Ran: on our test head unit (060): installation in one pass (45 seconds), Android Auto (also after a restart), switching phones; CarPlay ran there with the in-between version 0.14.5. On 104 the in-between version 0.14.4 ran with CarPlay; the 104 menus of 0.14.6 have not run on any device yet.

Connect app 1.9.17 · includes the internal versions 0.13.5, 0.14.0 and 0.14.1

• New: wireless Android Auto (experimental) — off after installation, switch it on under Settings › Connect › Android Auto. Only one runs at a time: Android Auto or CarPlay.
• New: switching phones — tap a paired phone in the Bluetooth menu: it connects and starts CarPlay or Android Auto, and the previous one is disconnected.
• New in CarPlay: two-finger zoom; the car icon takes you back to the car's home screen.
• Smoother CarPlay: the head unit sends its second picture (over HDMI to the instrument cluster) at 45 instead of 22.4 Hz. That had held CarPlay back to about 22 frames per second; now it's about 27–30 (measured in one car, with 0.14.0 and this setting made by hand). The cap is now 30 frames per second.
• New: an up-to-date SSH server (dropbear 2026.94) with scp and sftp; the keys survive restarts.
• Changed: WLAN (the car as a Wi-Fi client) is off after installation. An update keeps what you have set. If the installer can't put something in place, it ends with “UPDATE INCOMPLETE” instead of “OK”.
• Fixed: the installer did not always recognise our own menus from an earlier version and then skipped them without saying so. 0.13.4 also set the CarPlay frame rate to a fixed 50 (in one car about 2 seconds of lag when swiping).
• App builds 060 and 104 got only the core in this version, without our menus; the “UPDATE INCOMPLETE” ending is expected there.
• Ran: on our test head unit (052): installation, SSH with scp, CarPlay. In a community member's car (060): installed twice (with the expected “UPDATE INCOMPLETE”) and removed twice with the rollback stick — both rollbacks completed. The in-between version 0.14.0 ran in a car with 052.

Connect app 1.9.12 · the first version available for download

• Bluetooth, CarPlay and the connection menus run on our own code instead of the manufacturer's: wireless CarPlay over the car's 5 GHz hotspot, Bluetooth with pairing, music with track info, hands-free calls with call audio and phone book.
• Settings › Connect with pages for CarPlay, SSH, Ethernet (USB network adapter) and ADB; the home screen shows the connected phone and the network status.
• USB sticks: the Connect app shows what's on a stick — an ADC update, the stock firmware or the 3D parts catalogue — with the matching action.
• A self-test after every start (/sdcard/OpenAiways/selftest.txt), an installation log (/cache/oa-install.log), a rollback stick for removal.
• Ran: in a car (052) on 9 October. The core ran, but our menus from an earlier version were skipped and the frame rate was too high — both corrected by hand, fixed in the installer with 0.14.2.

Older test versions (0.9 to 0.13.3, from 25 September 2026) only ran on our own devices and were never available for download.
