I love the big beautiful screen Pumpkin head unit! I hated having a small screen for my back up camera because I felt it was a hassle to use and now this makes it perfect! I can see everything when I'm backing up. The screen is very responsive and doesn't lag at all.my phone paired up with the stereo really fast and easy just had to put in the pin. All the apps work just as on my phone I even was able to set up nova launcher. Calls seem to work great haven't had a issue where no one couldn't hear me.
