Hi I had already sent what was requested on another post of mine.
anyway here is the screenshot.
unfortunately the android version no longer supports some apps.
I am also having a problem with the time when you start an app that uses the gps, map or waze the time changes and goes back by an incorrect time and date. this does not allow to take advantage of the internet connection.
therefore I need to update the car radio

Hello
Thanks for your message
Could you please confirm the SKU number of your car radio?
If it is RQ0368E, please download this firmware to refresh the system, it is still the android 5.1 version
Refresh system risk of the damaging car radio and can not recover, if your car radio can work, it is better to keep current firmware.
