construction of display is sturdy, much better than i expected. radio has RDS, color of buttons is nonstop changing, but its possible to turn this off in factory menu and choose individual color. didnt test power drain so far, but i expect it not to be little, this can be overcomed with cutting yellow wire (constant power) and twist it together with red wire (ACC power), so the radio will perform cold start after ignition is switched on. cold start is quite quick (less than 20 seconds), so i dont see this as issue. big advantage is that there will be no power consumption at all while engine is off.
already installed in car which was a bit difficult as there was too little space (VW T4) and radio is too long and has too many non detachable cables and wires. but i was successful in the end and everything works.
I am satisfied with the purchase, the package is well packaged, the package arrived very quickly.
