Renault Radio Problems

Hi all. One of my work colleagues is having problems with her radio in her clio intermittently refusing to turn on, regardless of whether the ignition is on or not. Sometimes will turn back on but most times need to take it out and disconnect then reconnect the leads for it to reboot then lasts about a week before doing it all over again. Any one got any ideas? or does it sound like it knackered. Oh btw its a 56 plate so out off warranty. Thanks for any replies in advance. :thumbup:
 
renault know about this problem - shame it isnt under warranty - i would still head to the dealers and see what they have to say - its happened to quite a few people, myself included!
