QUESTION: thank you for your advice but i have tried this already and it doesn't helps, then i tried to clean cd and bought special celaner for it but nothing... on central console works only one button... Have u any other idea? thanks beforehand

Answer
hello sorry for the delay but i was taken into hospital unexpectedly but did you get you problem sorted out if not i have had a look at a similar model and found that the small wires that connect the various modules together can break and if this is the problem then it may be more simple to replace the head unit with a second hand one form a breakers yard they are quite easy to remove and only took my mechanic around an hour to remove and replace just to see if this is a possible repair done by a diy mechanic and it should go well after
