510 is double DIN, whereas 210 is single DIN.

But i think Polo, has a bigger casing frame with a pocket to keep things at the bottom right? Maybe a picture would help.

If it is so, you can change to double DIN. But why 510? Dont like after market HU?

As voscar indicated, also always check your average speed for the mileage you are observing (calculating).
If there is aloy of stop/go and idling, obviously the fuel consumption will be higher. And dont use fuel tank balance for any calculation. Go by tank size (Liter). Half a tank indicator may not be accurate

Im just guessing here, you fuel tank is about 40+L, so it would have taken about 400+km to finish the tank, hence its about 10km/L, thats pretty good for a city driving.
