Hi,
I've bought a new Head Unit, and I wired everything on the car.
It's working like a charm, but, there a big but.
The Head Unit which should go to sleep / deep sleep or whatever when I remove my car key after 30 seconds, stays on.
For the time being I've unpluger the ACC cable (the red wire) so that the Head Unit only receives power when the car key is plugged in.
Do you know why am I facing this Issue and how to resolve it ? I had hope to enjoy a fast boot and not a full boot everytime I use my car.. it would be nice
I have another question also, if you know about it, I'm trying to get the light buttons always on, because they're not very visible to me. Si I went to the special menu (with the 126 code) and tried changing the parameter "Power LED control" to "By Power" instead of "By head light" but they still won't turn on unless head light is on. Am I missing something ?
I'm not sure what head unit you have but a) what is your amp wire from the head unit connected to? B) there's is usually an illumination wire, what is that connected to?

Also do not know what head unit you have but it sounds like it is not wired up correctly.
If you dont get much help on these forums maybe go visit an auto electrician as they should be able to advise further.
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 ?
Hello everyone,
I have the following chinese head unit. When I switch the ignition off, it only closes the screen but the head unit itself keeps operating.
It keeps paired with my bluetooth and hotspot. Doesn't shutdown.
I tried to install an application for shutdown and when I use it is shuts the unit down and then reboot it..
I tried to enter the factory settings and switch it to direct shutdown but no use. I also tried to enter from the factory settings (Engineering debugging menu) and switch it to user settings but still no use.
Can anyone help how to shutdown this head unit?? It keeps draining my battery as it when I tried to measure the parasite load when it is running but screen shutdown and it was 0.6 Amps. which is a lot...
My last resort is to make an external power switch to it.. which I really don't like but what can I do...
Waiting for your feedback as you might help me with it!
Thanks in advance.
Mine has a connector for demo mode that I had to unplug so the head unit will turn off when the switch is off
So you have to physically pull out a connector for it to power off...
But in this case it won't shut down... you will just cut the power off it. Isn't that harmful to the unit hardware and software?
There are two reasons why unit is not to shuting down...
First - in "settings" or "infotainment" area find UNIT TIMEOUT / SHUTDOWN SETTING , must be at value "0 min" instead of max min.
Second - Red wire (ACC+ KEY) from cable harness is connected to 12V battery constant (usually it is yellow wire), switch those and see if helps. Key for ignition must turn unit off when shuts down engine.

I already connected the Acc wire to the Acc, that's why when I switch the engine off and remove my key the unit only closes the screen but it doesn't shutdown.
For the Unit timeout option, or shutdown option, I can't find it on my unit OS... tried the search function and tried going through each and every bailable list and choice but didn't find it!!!!!!!!!
Connect both ACC and +12V wires from HU to car ACC. This way, when ignition is off HU power is off.

Don't think that's a good idea. Because this will interrupt power supply completely when you turn off ignition. This way the head unit has no chance to shutdown or switch into sleep mode. It's like removing the battery from your laptop.

I don't know your head unit but there may be an ACC delay option.
Some head units allows to set up a waiting time up to 60 minutes before shutdown/sleep.

Exactly, that's my point of view.

There is an option for that just need to find it, if not in settings or in infotainment area try in factory settings
Okay as an update for the situation,
I couldn't find an option for it, however, I installed an APK file for shutdown and restart.
In addition I rewired it so that the main +12V wire to an (on/off) switch, when I want to shut it down, I just use the APK I installed, wait until it shuts down, when it tries to restart again I use the On/Off switch to permanently power it off....

Ok , but there is no need for application, on factory settings when you type in PIN codes just enter PIN 1414 and device will shut down, that is code for my device.

Really?? didn't know that.. I will try it and let you know the result.
Thanks a lot
Did you find a solution for this issue? My head unit stays in sleep mode forever and does not turn off, although I have set the sleep delay in factory settings correctly.

What is wrong with sleep? Answer: Nothing!

Sleep delay? Are you talking about ACC delay?
Nothing is forever but how long is your forever? Usually the head units stay in sleep mode for around three days before shutdown.

Yes ACC delay. The delay is configurable. I have set it to 10 - there is no unit, but the unit does not turn off after 10 (seconds|minutes|hours). As maximum is 3600, I presume the unit is not days.

ACC delay means: how long to wait before entering sleep mode after ignition is off. This has nothing to do with the sleep duration. I don't know any head unit which allows to configure sleep duration.
[ign off] --> [ACC delay] --> [start to sleep]
