First of all, the delivery was super fast! I haven't installed it yet, but I paired the C6 to my phone and it seems to work fine. I opened Google Maps, but I don't see the speedometer, not even on Waze. I'll try downloading the new firmware and hope the speedometer appears on the display. The touch screen isn't as responsive as other devices from other brands, and that's a serious issue. What will happen with winter gloves? I have a CarPlay device I bought on Aliexpress for €35, and the touchscreen is better than the AOOCCI C6. I also connected the cameras to test the quality and I'm quite satisfied, but they're too large compared to my current video system installed on my motorcycle, which I bought on Aliexpress for €25. Furthermore, you can't rotate the camera because the cameras only have one mounting direction, and you have to waste time finding the optimal configuration. If anyone asks me for advice on whether or not to buy the C6, my answer is NO, because in my opinion it's not a good value. I will try to install the C6 on my bike to test it well and I hope for new better updates soon and so I will update my review.
