That could be another thread all together. I did a lot of research into the native android head units, and on the xda developers forums, the ATOTO A6 pro got the best reviews and recommendations. I’ve only used this in several installs now. And I’ll keep with the recommendation on it. There are front, rear, and subwoofer amplifier outputs, so if you need it loud, it’s very easy to get carried away. The internal amp is 30 watts RMS, so it’s more than enough to add volume and clarity to a factory speaker system. Sound quality specifically is absolutely improved over factory sound. The dual Bluetooth, WiFi, and GPS antennas make it seriously capable. Typically, I turn on my phones WiFi hotspot, and run pandora, Waze, google maps, etc... right on my dash. But having access to the google play store, I run an app called Torque pro ($5) that talks to a $12 Bluetooth OBDII adapter, and allows me to generate custom gauges on things the vehicles computer sees. Also scan, and clear check engine lights. I’ve got a dash cam, and a backup camera connected directly to it, and still have 3 available USB ports. I’m a little tempted to try a SWR app and usb dongle on it. But it has given my 1999 Chevrolet more modernization than anything else I could have done. Sent from my iPad using Tapatalk
