[Android Head-Units] BiliTheAxe:
I just purchased an Eonon G2150F Double Din 6.2" Android 5.1 Car Stereo and so far it is working well.

One thing that I have noticed that is different from the earlier models I have owned from various vendors is that using the rear USB ports it can run an external hard drive. I currently am using a 1 TB drive and it is working perfectly without having to use a 12 volt USB hub to supply the power for it. The advertisement on the Eonon ebay page for it clearly says it will not work, but it does, and very well.

The GUI is not the flashiest I have seen, but it runs fast and gives no issues as yet.

Another nice feature is that I no longer have to wait 30 seconds to do anything with the head unit like I did with my 4.4.4 android quad core that proceeded this one.

It utilizes that instant on feature where the unit does not shut down, but instead goes into a low power consumption state.

Torque works well, but only blue tooth obd2 adapters that don't use a pin are accepted or USB ones. Mine has a button on it that when pressed allows the head unit to find it and pair with it the first time.

it does not come preloaded with tons of useless apps like so many other android devices do. The apps are all useful and easy to find.

I have not as yet been able to root it, so if anyone knows of a way to root it, please let me know.

Here are the specs for it.
