Who makes the one you got?
List of issues I had with the unit I got that looked identical (Made by Kirinavi):
Wifi turns off whenever you turn the car off. No matter what I did I couldn't get it to stay on.
Google maps was unusably slow. (20 second screen render times)
Outside Temperature always reads 30deg C
If you turned the car off with the heat on, the next time you turned the car on the blower would turn on cold until you tapped the temperature adjustment, then it would jump back to hot.
Adjusting the fan speed was slow and unresponsive compared to the OEM knob. You had to wait like 1-2 seconds between tapping, and each tap would only change it one step. You could not jump to the level you wanted.
Hazard light switch just had two blunt cut wires with no explanation of where to connect them. The unit came with no instructions whatsoever.
The output of the CANBUS box that had the reverse output was opposite polarity of the reverse camera trigger input making the OEM backup camera on all the time EXCEPT in reverse.
Could not use any other music player other than their crappy one that didnt even have a proper shuffle. I tried VLC and it would not play more than 30 seconds if you switched screens.
Volume would reset to 10 every time you started the car (though I found a very buried setting in a hidden app that fixed this)
There was no way to change the temp display on the HVAC to F. If you changed the C/F setting, it would change the label, but not the actual temperature. I see you don't have this issue.
Brightness control was very limited. At night it was still really bright even at the minimum setting. Had to install an app called Lux to get it lower.
Even with all these issues I probably would have kept it if it wasn't for the fact that the screen was black when wearing polarized sunglasses. Because it's turned into portrait mode, the LCD polarizer is 90 deg out of phase with sunglasses and you can't see the screen at all. Living in the "Valley of the Sun", I always wear polarized sunglasses so not being able to see the screen is really annoying.
Despite them telling me "don't worry we'll fix the issues, but if not we'll give you a refund" (how will they fix the polarization?), I was getting no where with them and I forced them to take it back, and then they stopped replying when they got the package. I had to file a claim with my credit card for $750 and it cost me over $100 to send it back.
I have a video half edited about it.. just been super busy. I'd never make it as a full time youtuber.. lol.
