don't update lost RCA outputs.
An even newer System Firmware ATOTO OS AICE OS 9.4 is in development and is estimated available 3 weeks later. If you never found any noticeable issues or improvements of current firmware update are not your most concerning, you can wait for the to be released new firmware.

Went back to the firmware before and everything is working fine

ATOTO has released a few firmware update since ATOTO A6 is available, and the latest ATOTO AICE OS 9.4 has the most
changes and now it is available for download & update manually. At the bottom of the document, there is a link for
downloading the new firmware.
Here are some of the changes in this firmware update:
1. Includes support of ATOTO Hands Gesture Control feature, which is the beta feature available on ATOTO A6 Pro.
Current A6 Premium/Standard products do not have hands gesture sensor inside, so will not be available for
2. Includes support of latest Qualcomm Bluetooth 5.0 with aptX feature, and though it is available on A6 Pro version,
the optimized firmware allows current A6 Premium/Standard users to see phone phone signal strength/battery power
on A6 notification bar(see images below)! ATOTO A6 is the first Android car stereo brand to synchronize phone signal
and battery power on car stereo screen!
3. We also included a screen lock option in system settings for users to lock the screen when the car (car stereo) is not in
their control (Valet Parking, vehicle taken by others), in order to protect privacy. Local media apps (Radio, BT Music,
Video, AUX) can still run next time when car is ignited, but there is a password input window to block non-authorized
users to access sensitive personal data; The downside of enabling this option is users need to input password
every time when system finishes booting;
4. This issue that A6’s Wi-Fi MAC address changes randomly every time when system finishes booting has been fixed.
A few ATOTO users who want to let A6 connect to specified router hotspot found that once they enable the
MAC filter option from Wi-Fi router hotspot, ATOTO will not be able to connect to the router next time, until
changed/new MAC address from A6 has been added to router. Now this issue has been fixed, and it even
allows user to revise & input the MAC address they want to display from A6!
