Regarding how long it too to receive the unit from auto tech, about 2 weeks. It was over the Xmas holidays so that could have played a roll in the speed. I also Ordered a VIKINAV unit from Ali and it came faster. The VIKINAV is supposed to be Android 12 but the package was identical to Autotech’s stating Android 11. I asked the seller what was going on, he said Android 11 is the newest, I tried to call him out and just get the canned response that it’s a good unit and try it. I have it, maybe I’ll take some time when I actually have time to compare - they look identical down to the sticker part number, so not sure if the screen res is different. Hope you get yours soon. Chinese New Year is another’s and that will slow things down.
