After two full months of operating this unit I can safely say that it is very impressive. First of all the screen is phenomenal. It is extremely clear and bright under the most sunny conditions. Even the fact that the resolution is quite high, you can read any small characters fine.
I have spoken to other people that are using units like this, and speed of running apps seems to be a problem with them. Not here. Apps always run fast and smooth, and i have never felt that anything is slowing down.
Although I have tried their Apple Car Play, which works as expected, it is totally unnecessary because all the apps are running directly in the unit and have a much better display and functionality. Car Play is blocking a lot of features for driving safety reasons, but it is too restrictive. This unit works like a tablet that is focused on driving.
I enjoyed how easy it was to upgrade over the air. I did one upgrade recently, and it was ready to go with the new feature I needed (switching from internal to external mic) plus a ton of fixes. T'eyes are really putting a lot of effort in updating and maintaining the software and it shows.
I have found a few bugs here and there, but there are solutions for everything on the internet forums so I am not stuck anywhere yet.
Overall I really recomment this and would definitely buy again
