Hello!
I recently got a Android Headunit and so far its been working perfectly.
However I have an issue, everytime the headunit starts (no matter if cold or warm boot) it resets the volume to 50%.
So I change it to 80% and after a new boot it reverts to 50%.
Any way to keep it at 80%?
Or set a new default volume of 80%?
Thanks!

Hello everyone,
I just installed a eunavi head unit.
First of all it doesn't have acc delay off function. There are no options in the menu and the seller told me that it's not possible. I tried to connect the acc line with an external battery but the unit still turns off while cranking the engine. (I have verified that all the connections are correct). I suspect that it has to do with the voltage drop of the car battery while cranking the engine. My next project will be to install an auxilary battery (a small one, 12V 2Ah). While the engine is running, the unit will be using the main battery. The small one will be there to supply current while the engine is cranking and it will be charged from the car while the alternator is working. It will also power the acc line using a delay off circuit.
My question has to do with the shutdown process. When I put the key on the off position, the unit turns off almost immediately. There is no any message on the screen telling me that it's turning of. I put an ammeter on the power line to see what's happening while it's turning off. After cutting the acc line, in less than 1", the current dropped from ~900mA to 50mA, after 1" to 33mA and then to 16mA. After 3-4" it dropped to 3mA and it stays there. Is this normal? Could this behaviour harm the unit? Should I be concerned? How could I check it's shutting down correctly?
The power button doesnt turn off completely the unit. It turns off the lcd but the unit still gets 700mA. There is a secret menu that could change the button function from "false shutdown" to "true shutdown". If I select the "true shutdown" and press the button the unit turns off like when I cut the acc line. Is this a good sign?
Thank you
anyone?
I've noticed that if I shutdown the unit (by turning off ACC power) while some apps are open (like the music is playing), the next time I turn it on, the apps are opening automatically. It this a good sign that the unit is shutting down properly or the same thing would happen if it shuts down violently (by cutting the power line).
Could anyone explain us how the MCU shuts down the unit properly? Does is trigger a pin on android to perform shutdown or it sends a command using a communication protocol (like UART).
I don't know what happens on mine but I suspect that the MCU cuts the power on the Android if it doesn't get power on the ACC line. I was thinking if that would be possible to send a shutdown signal on Android (using hardware or software mod) when the ACC power is off.
Hi Everyone!
I've recently installed a Chinese (Funrover) Android HU into my 7th gen Honda Accord. For the first few weeks everything worked fine. Then I tried to install the rearview camera that came with the HU. On the first try before putting the camera to it's final place I tested it and it worked fine. After I put it in it's actual place and tried again, it didn't work. The camera lights up, so power is fine but the HU doesn't switch to the camera's feed.
Next day I had some issues with the HU - the sound just went away. This still happens randomly.
And now recently the HU started turning off randomly, sometimes it doesn't even start up when I start the car. It does work sometimes though. Also it sometimes tries to power on en-route, but usually fails and goes blank again in a few seconds. I noticed that this usually happens when I'm braking and also at the same time the car's original built-in bluetooth unit (which I've never used so I'm not sure how it works) would flash it's leds as if it's getting power from the same source.
Does anyone have any ideas what to check / how to fix this?
Thanks in advance
(let me know if you need any more details)
Hi I have an android head unit for my car that I have managed to mess up by putting Spotify into the auto start slot (was navi) as I thought it would be good to come on at the start. The problem I now have is that is has the volume of the sat nav which goes down to 3 and then off. I've tried pressing the reset button on the front of the unit (nothing changed) and also uninstalling Spotify/Navi/maps and it's still the same ???
Is there a way to factory reset these head units?
Thanx for any help I receive ?
anyone ever used this unit or one similar from the manufacturer? the problem I have is if i change android settings unless i make the unit to a reboot from the notification bar if won't hold the setting when the key is turned off and back on it doesn't even resume playing music automatically.
I have an Xtrons PX5 that was already installed in my vehicle when I bought it. Something strange is happening with the volume...
The volume slider in Android keeps resetting to 12 every time the unit is powered off and back on. I like to keep this higher (around 20 to 30) as it gives a higher level to my OEM head unit aux input.
It's kinda annoying that I have to increase the volume slider every time the vehicle is switched on. Any ideas on why this is happening?
Have also tried setting the volume in Settings -> volume but still it resets back to 12 every time.
I have the same issue, it's really annoying!
What does reseller suggest when contacted for support

Garry after having a good poke about I have fixed it. You need to set your default boot volume to 30, this is done by accessing the factory settings menu within the unit, then the setting is under the "Other" tab at the top right. you can also change the boot logo there also. see attached. PM me if you get stuck, I used the passcode of 126 to access this menu.
