Remove the fascia sorrounding the radio, and then loosen the torx screws holding the radio itself. After this you have to ask someone with a really small hand to reach the radio from behind, coming from the air inlet area in the engine bay. He may have to fight against the blower motor and the pollen filter, but after around a 1m journey he'll reach the very end of the radio and will be able to push it out for you! 
Thank you, wow that's fast Sir, so if i remove the fascia and torx screws, do you mean that i still can't pull the radio cassette?
Sir, i'm just a little bit confused can i pull direct the radio when i open the screws? air inlet area in the engine bay? i don't understand Sir.
