Can I have some help please . 
 

See the attached pictures . 
 

Radio powers up but has no sound and is overheating. 
 

I have no idea how to fix it . 

Was going to fit one to my folks old fabia but I'm like you and got into problems. Did read that on some there is a diagnostic wire which shouldn't be connected to aftermarket radio. Think it was pin 3 in the yellow block. The blue block I think is for CD although mine was purple. Another thing was switching lives around. Think red and yellow to stop radio losing stored data. I'm not an expert so I wouldn't go switching wires until someone else confirms it but you could try removing pin 3 wire and see.

You could also check if theres an adapter?
