what size is optimal to fill ~full area?

from downloaded ger_radios_logo.zip i have read size 160x120 pixels

and tried make my own icons -

none of size(160x120; 200x150; 280x210; 280x250) fills same amount of area as preinstalled icons

 

first(black shows real size of pic), second and fourth are self made, others original pre-loaded

I just used any image and it filled the small I believe - however if you switch to radio text view (with the large icon) it doesn't display

downloaded exactly same icons from
http://webspecial.volkswagen.de/infotainment/de/de/manuals/stationlogos.html?d1=discoverpro-2
and uploaded to Columbus just one to compare -
second station logo uploaded trough USB vs third pre-installed from the factory
