Looking at trying to fit a reversing camera into my 2016 Fabia. This is the camera I wanted to fit, been doing research and looking at post on this forum and elsewhere, from what I can find only some head units can use the camera, i tried to figure out if mine can or not, from what I've seen I think mine would be compatible, but wanted to check before I order anything. Photo of my head unit attached

The bit I don't like is the white border around each individual icon. Its like the icon dose not fit inside the square, if that makes sense?

I recently got my skoda, I downloaded the dab radio icons to add the missing ones to the radio. However, they are small and have a white border. Dose anyone know how to make the logo take up the whole box?
