Appreciate it! On the Axxess website, the install info for the GX says to connect to pins 6,7,8.... I considered the phoenix/Tesla style head units but I just don’t trust Android and they’re made in China. I was just concerned with long term quality and functionality. Also, the expansion is limited; If you want to add amp(s), siriusXM, cameras, processors, etc. perhaps some of that can be done (SiriusXM app) but I wanted something I know, and Alpine, like Apple products just work and they work well! The Tesla style is very cool, clean look! I got my Alpine for about the same price... I guess it’s what you want!
