[Android Head-Units] rigattoni:
whow... calm down... I´m just telling you that it is not even planned. Feel free to ask them yourself. I did it...

No, i´m just one who is playing around with these units since a couple of years now, and I´m in good personal contact with some of these supplier and some developer on their side. If you would know anything about the Chinese culture you would be able to understand that this has nothing to do with European or US culture in business. I know about these problems, because I daily have contact to our offices in China, corresponding with them and I have daily phone calls with these colleagues.

...and NO it´s not a matter of software, it´s a matter of hardware changes to get a unit powered.

I don´t know who told you that it would be a SW issue? Are you hardware expert, or developer for these things?

A function for getting the unit powered even if clamp 15 is off is not planned and has always been declined.

May be you don´t know that the OFF button does not even switch off the unit?

It just switches the screen, the buttons and the amplifier to OFF... nothing else. The unit itself is still completely working in the background. There is not even a plan to get it switched off completely.

On the other side, all these units are from version to version more closed.

To get root access is even more difficult and only some good guys in here doing tests in their free time to get it working, in danger to brick their own devices , payed with their own money.

Launcher?

Sorry, but there are tons of launcher in the wild which are able to get buttons and own created widgets working on the desktop. All launcher from Chinese units are completely useless and this is since the first android devices I know of. You have to change that yourself if you want more than they deliver. Android gives you the chance and the possibility to do it. You just need to do it.

You really need examples?

Nova, Fcc Car Launcher, AGAMA... and a lot more.

At least, the top bar could be removed or hidden... For removing you just need to get rooted and invest some time and the right apps. For getting it hidden you just need to use ADB.

You will loose some features of the unit, but you will win some additional ones with the right launcher.

If you want to change anything, do it yourself or use any other unit which is not developed in China. Ah wait, I just forgot, that you even won´t be able to change anything on aftermarket high end units from Pioneer, Kenwood.... They are completely closed and you won´t even be able to install another launcher.

Android head units need some own spent time, a learning curve, and own ideas. XDA is one of those places where you can find ideas, solutions, and help, you just need to search and to do it yourself... Otherwise use the delivered software and keep it as it is.

That´s the current situation and on the horizon no change is visible for now. You need to live with it, or don´t... always your personal decision.

Just one thing to be added:

Even if Torque tells you that it can run all the time:

Let me tell you from my professional perspective, that it is not a good idea to have a dongle all the time connected to the OBD port. Whether the OBD nor the dongles are developed for continuous operation. It´s only for reading error messages on demand, not for satisfying your human drive to play.

Having an OBD dongle continuously connected is not recommended and can damage the gateways on dongle damage. Would not be the first time that the CAN gateway get´s damaged by those cheap Chinese dongles.... but it´s your car and your money. I just can point on it.
