I'm really happy with this stereofor my Ford Mustang. The software is fast and stable. The screen is of good quality and the possibility of expanding the capabilities are endless as it is a system Android. Personally, I have connected a USB hub to which I connected: n.1 pendrive 32GB, n.1 Microsoft wireless keyboard with touch pad, n.1 receiver wireless for xbox 360 joypad. I installed Teamviewer to connect and work on the PC I have in office, I plugged in the pendrive music videos in 1080P, I installed arcade emulators such as MAME, the video surveillance software of my house and much more. The DVD player is very fast initialization, the Navigattion GPS Software works well and is upgradeable. DTV also runs quietly. So I'm really happy with my purchase and the technical support provided in post-sale.
