Yesterday I upgraded my 5.7 screen to Android system HD (1080 resolution) with capacitive touch-screen 7" (the vendor told me it was 9"..)
It have Bluetooth, WIFI, GPS, TV, SDcard, 2 USB an wireless rear camera which I have not yet installed at this time.
You can operate the menú from the original buttons console, and change to the original screens.

I bought it with other colleagues on aliexpress, The price including android system+screen, camera wireless, shipping, customs was only 415 euros!
