My experience with their support is different than yours. Their engineer is in china but they would respond by email in 24hrs. They have sent me replacement unit of rear camera, front cable, rear cable, new software update, and the last bit that solved all issues was the new mirror cpu module...
My original AT tires had to be replaced at 22k as the vibration started after the inner glue detached. Changed to plat Michelin and I’m driving a new truck again. Smooth and vibration free! Discount tire usually has $100 off a set with their rotating discount.
The version 2 is really good. I have been using it the last few weeks. I only installed the rear not the front camera. Shipping was little slow as it shipped from china. I had some freezing issue but once I replaced a new sd card, plus they sent me a new software update, it’s been working...
It only came on after a supercharger session and never again. I just took a screenshot of the turtle, made an appointment just to wait and see. They diagnosed it and replaced the inverter. Only left the car there for 1 day.
