Renault Megane Radio?

Hello I have a Renault Megane I have a problem with the radio most times the radio digital doesn't show the radio some sometimes it does but when it doesn't you can still here the taking and music on it. I'm going for a new Radio. Have to wait for 2 weeks for a part from Halfords I have the new radio picked out Can't wait to try it you can connect 2 phones to it at once ipad I just hope there's no running into trouble after reading most of what is going on with radios in Renault..
