Roadmaster screen Android 9.0 system 4 GB RAM, 32 GB storage It has very light scratches that do not affect it at all. It has never been opened or sent for maintenance. It is very excellent, no lag or slowness. I had Shahid and Thamanya apps installed on it and it was wonderful. I never complained about it. It fits Yukon and Tahoe from 2007 to 2014. However, the problem I faced with it, which is not continuous, is a buzzing or ringing sound from the amplifier because my car is fully loaded and the screen is not compatible with the Bose Denali speakers. For those whose car is not fully loaded, it will work perfectly with them. Starting the bid at 300. Whoever offers more is welcome.
