[Android Head-Units] cavemancan:
This thread is really to help me choose which Android 8.X head unit to install in my Nissan 370z but I am running into some unanswered questions that I really want answered in order to make the right decision. I already did some research and I am cutting and pasting that down below from another forum. Hopefully in the process this could help others decide on a double din Andriod 8.X HU.

With that said my questions:

1) Has anyone been able to figure out what the preamp voltage is for these units? In my research literally only 2 companies have posted there voltage and not for all of there units. For example Joying...I only saw the voltage for one of the units which was 2 volts but ATOTO on the other hand states most of the late/New units have 4 volts. All other brands don't mention a thing.

2) Do these built in DSP's actually make a difference or is it marketing?

3) Would I need an adapter for the 370 z to keep steering wheel controls?

4) Is there a way to modify an ATOTO A6 with gesture for example to use a 15 band EQ as apposed to the stock 10 band?

5) Can you use any USB DVD/CD player with these units to play music? Or does it have to be a specific one? I ask cause I have a USB DVD player laying around.

6) Does anyone know what the audio frequency response is for the units mentioned below?

Research:

I decided to share my research with the community to save others time that I clearly invested way to much of looking into the right setup. Here is some data I accumulated while comparing all the Android OS based head units. Note I was only looking for head units with Android 8 or above & I leaned towards the units with no buttons when available due to ascetics so this is not an end all be all list.

Note: the following head units have the following in common unless otherwise pointed out...Android 8, DVR & Reverse Camera options, OBD scan tool option, iPhone Mirror, 4 GB of Ram, WiFi Hot spot, Resolution of 1024x600, and RGB Buttons.

What you see above is a combination of whats on various websites and even some emails to the vendors. It may not be 100% accurate but it's the only place you will see all this info in one spot as far as I am aware. If any of the info is incorrect please let me know and I will correct it on this page but make sure to post a link to the info for reference.

Thanks!
